MOBI is the name given to the format developed for the MobiPocket Reader. It is currently used by Amazon with a slightly different DRM scheme and called . Amazon uses this extension for files created by
even though they actually have both a MOBI format and a
format inside the same file.
MOBI is the format used by the
Readers. It may have a .mobi extension or it may have a
extension. The extension can be changed by the user to either of the accepted forms. In either case it may be
protected or non-DRM. The .prc extension is used because the
doesn't support any
or . Note that
prohibits their
format to be used on dedicated eBook readers that support other DRM formats. Mobi source files are based on the , Open eBook standard.
MOBI format was originally an extension of the
format by adding certain
like tags to the data. Many MOBI formatted documents still use this form. However there is also a high compression version of this file format that compresses data to a larger degree in a proprietary manner. There are some third party programs that can read the eBooks in the original MOBI format but there are only a few third party programs that can read the eBooks in the new compressed form. The higher compression mode is using a huffman coding scheme that has been called the Huff/cdic algorithm. For a description in Python check
available as part of the
From time to time features have been added to the format so new files may have problems if you try to read them with a down level reader. Currently the source files follow the guidelines in the
is the same format as MOBI except that it uses a different
scheme. Amazon owns Mobipocket. The format description below applies to both file types.
Like PalmDOC, the Mobipocket file format
is that of a standard
file. The header of that format includes the name of the database (usually the book title and sometimes a portion of the authors name) which is up to 31 bytes of data. The files are identified as Creator ID of MOBI and a Type of BOOK.
Mobipocket have some minimal file format info, mainly about the html encoding they use in the text of the book, at
The first record in the
gives more information about the Mobipocket file. The first 16 bytes are almost identical to the first sixteen bytes of a PalmDOC format file.
Compression
1 == no compression, 2 = PalmDOC compression, 17480 = HUFF/CDIC compression
Always zero
text length
Uncompressed length of the entire text of the book
record count
Number of PDB records used for the text of the book.
record size
Maximum size of each record containing text, always 4096
Current Position
Current reading position, as an offset into the uncompressed text
There are two differences from a Palm DOC file. There's an additional compression type (17480), and the Current Position bytes are used for a different purpose:
Encryption Type
0 == no encryption, 1 = Old Mobipocket Encryption, 2 = Mobipocket Encryption
Usually zero
The old Mobipocket Encryption scheme only allows the file to be registered with one PID, unlike the current encryption scheme that allows multiple PIDs to be used in a single file. Unless specifically mentioned, all the encryption information on this page refers to the current scheme.
Most Mobipocket file also have a MOBI header in record 0 that follows these 16 bytes, and newer formats also have an EXTH header following the MOBI header, again all in record 0 of the PDB file format.
The MOBI header is of variable length and is not documented. Some fields have been tentatively identified as follows:
identifier

0xFFFFFFFF In new MOBI file, the MOBI header length is 256, skip this to EXTH header.
0xFFFFFFFF In new MOBI file, the MOBI header length is 256, skip this to EXTH header.
0xFFFFFFFF In new MOBI file, the MOBI header length is 256, skip this to EXTH header.
0 In new MOBI file, the MOBI header length is 256, skip this to EXTH header, MOBI Header length 256, and add 12 bytes from PalmDOC Header so this index is 268.
If the MOBI header indicates that there's an EXTH header, it follows immediately after the MOBI header. Since the MOBI header is of variable length, this isn't at any fixed offset in record 0. Note that some readers will ignore any EXTH header info if the mobipocket version number specified in the MOBI header is 2 or less (perhaps 3 or less).
The EXTH header is also undocumented, so some of this is guesswork.

At the end of Record 0 of the PDB file format, we usually get the full file name, the offset of which is given in the MOBI header.
There might be data of unknown use between the end of the EXTH records and the name.
The name is followed by two null bytes, and then padded with null bytes to a four-byte boundary. For example, if the name is 16 bytes long, with two null bytes, that makes 18 bytes, and it then gets another two null bytes added to make it up to 20 bytes in total. However, the length stored in the header is only 16. If the name was 19 bytes, it would be followed by two null bytes to make it up to 21 bytes, and then padded with three more null bytes to make it up to 24 bytes.
The name and padding is followed by more data of unknown use, usually null bytes, to the end of section 0.
The first record of an index contains the meta data of the index.

The remaining INDX header values are unknown.
The TAGX section follows the INDX header and is essential for decoding the index values, as it defines which how many control bytes an entry contains, which bits correspond to which tag and how many values a tag requires (most tag need one value, but some have two, maybe more).
Identifier
the characters T A G X
header length
the length of the TAGX header, including the previous 4 bytes
control byte count
the number of control bytes
the tag table entries (n = header length - 12, must be multiple of 4 bytes)
The tag table entries are multiple of 4 bytes. The first byte is the tag, the second byte the number of values, the third byte the bit mask and the fourth byte indicates the end of the control byte. If the fourth byte is 0x01, all other bytes of the entry are zero.
Some parts of the Mobipocket format encode data as variable-width integers.
These integers are represented big-endian with 7 bits per byte in bits 1-7.
They may be either forward-encoded, in which case only the LSB has bit 8 set, or backward-encoded, in which case only the MSB has bit 8 set.
For example, the number 0x11111 would be represented forward-encoded as:
0x04 0x22 0x91
And backward-encoded as:
0x84 0x22 0x11
The Extra Data Flags field of the MOBI header indicates which, if any, trailing entries are appended to the end of each text record.
Each set bit in the field indicates a trailing entry.
The entries appear to occur in bit- e.g., trailing entry 1 immediately follows the text content and entry 16 occurs at the very end of the record.
The effect and exact details of most of these entries is unknown.
The trailing entries indicated by bits 2-16 appear to follow a common format.
That format is:
&data&&size&
Where &size& is the size of the entire trailing entry (including the size of &size&) as a backward-encoded Mobipocket variable-width integer.
Only a few bits have been identified
Data at end of records
Multi-byte character overlaps
Some data to help with indexing
Some data about uncrossable breaks
When bit 1 of the Extra Data Flags field is set, each record is followed by a trailing entry containing any extra bytes necessary to complete a multibyte character which crosses the record boundary.
The bytes do not participate in compression regardless which compression scheme is used for the file.
However, unlike the trailing data bytes, the multibytes (including the count byte) do get included in any encryption. The overlapping bytes then re-appear as normal content at the beginning of the following record.
The trailing entry ends with a byte containing a count of the overlapping bytes plus additional flags.
N terminal bytes of a multibyte character
Size & flags
bits 1-2 encode N, use of bits 3-8 is unknown
PalmDOC uses LZ77 compression techniques, an implementation for PalmDOC can be found at
. DOC files can contain only compressed text. The format does not allow for any text formatting. This keeps files small, in keeping with the Palm philosophy. However, extensions to the format can use tags, such as
or , to include formatting within text. These extensions to PalmDoc are not interchangeable and are the basis for most eBook Reader formats on Palm devices.
LZ77 algorithms achieve compression by replacing portions of the data with references to matching data that has already passed through both encoder and decoder. A match is encoded by a pair of numbers called a length-distance pair, which is equivalent to the statement "each of the next length characters is equal to the character exactly distance characters behind it in the uncompressed stream." (The "distance" is sometimes called the "offset" instead.)
In the PalmDoc format, a length-distance pair is always encoded by a two-byte sequence. Of the 16 bits that make up these two bytes, 11 bits go to encoding the distance, 3 go to encoding the length, and the remaining two are used to make sure the decoder can identify the first byte as the beginning of such a two-byte sequence. The exact algorithm needed to decode the compressed text can be found on the
PalmDOC data is always divided into 4096 byte blocks (uncompressed size) and the blocks are acte no information from previous or later blocks is needed when a block is being compressed or decompressed.
PalmDOC does have support for bookmarks. These pointers are named and refer to an offset location in a file. If the file is edited these locations may no longer refer to the correct locations. Some reading programs allow the user to enter or edit these bookmarks while others treat them as a TOC. Some reading programs may ignore them entirely. They are stored at the end of the file itself so the full file needs to be scanned when loaded to find them.
If the file contains images, they follow the text blocks, with each image using a single block.
The 4096-byte record size in the PalmDoc header applies
image records may be larger.
In some cases,
adds a 2-zero-byte record after the text records in a file.
This record is not included in the "record count" of text records in the PalmDoc header, and is also not used as the "first non-book index" in the MOBI header.
(If the 2-zero-byte record is present, the index of the following block is used as the "first non-book index".)
also ends files with three records: 'FLIS', 'FCIS', and 'end-of-file', in that order.
The 'FLIS' and 'FCIS' records do not seem to be necessary for
to read the file.
The 'end-of-file' record might be necessary.
The FLIS record appears to have a fixed value.
The meaning of the values is not known.

MOBI files created with Mobipocket creator, Amazon's Personal Document Service, or Kindle Direct Publishing (former Amazon DTP) don't include SRCS record.
In a past, kindlegen had an undocumented option to suppress this record, but the option was removed in 2010.
A SRCS record is a record whose content is a zip archive of all source files (i.e., .opf, .ncx, .htm, .jpg, ...) given to the command and puts it in the generated MOBI file.
The record begins with the "SRCS" signature and looks as follows:

This is the extension used on a side file (auxiliary) for MOBI formatted eBooks. It is used to store
used by the library software and also to store user entered data like bookmarks, annotations, last read position. This file is created automatically by the reader program when the eBook is first opened and has a .mbp extension. The Library management software in MobiPocket uses this file to get information displayed in the library window such as title, author, and description so that it won't have to open the larger eBook file.
There is an ongoing effort to describe the binary MBP file format (see ). There is also a
program that will extract notes from a mbp file
There are several ways to create eBooks in the MOBI format. The rules for the format of the source files need to create eBooks in MOBI are spelled out in documents on the . The recommended tool called
is available as a download
from the web site.
EBooks can also be converted from other forms using the Windows version of the . Once converted the file can be used on any device supported by .
In order to better support the features of the
there are some guidelines that need to be followed when creating a book in this format.
Do not specify a default font family, font size or other font attributes such as weight or color. This is a choice the person reading the eBook should be able to make. Fonts Sizes and Attributes can be specified for special headings and other specific items. Use only generic font families.
Do not impose justification for standard text. It may be needed for captions and other special text.
Do not use tables for anything except table data. Nested tables are not supported.
Do not use blank lines to try and force page changes. Use the &mbp:pagebreak/& tag.
Do not use multiple books for different devices. Instead use advanced features such as multi resolution images and platform specific frames.
Note that the following section only applies to the original mobi format and is not used by Amazon
The IMG tag in Mobipocket publications supports up to three source attributes for various resolutions: src, losrc and hisrc. This makes it possible to optimize the same ebook for various devices. The image to be displayed is dynamically selected by the Reader according to the resolution of the screen on the actual device:
screen smallest size
example devices
&= 239 pixels
Low rez 160x160 Palm devices (PalmVx, Treo 600, Zire) Smartphones (Nokia 3650, Sony Ericson P800/900, Microsoft smartphones)
&= 240 pixels (handhelds)
Pocket PC, Hi rez Palm devices (Sony Clie, Tungsten, Zire 71)
&= 480 pixels
any desktop or tablet PC
&img hisrc="cover480x640.gif" src="cover220x300.gif" losrc="cover140x140.gif"/&
Please also notice that there is a 63KB internal limitation for images (this is a restriction of the Mobipocket .PRC format). GIFs have to be smaller than 63KB. You can use GIF optimization programs such as Ulead Smart Saver to get GIFs smaller than 63KB. (If images are bigger than 63KB, they are automatically resized to fit in the limit by MobiGEN but you might not like the result). Jpeg images will use a lower Quality setting to get the image size down without reducing the pixel size.
Kindle and Kindle DX do not handle the soft hyphen HTML entity correctly.
Use the &shy/& tag instead.
Grey text is displayed as white on some devices.
To avoid this problem, add:
amzn-mobi and (monochrome) {
.mygreytextclass {
The kindlegen tool ignores padding-left.
If necessary, you can work around this by adding an element inside that element and setting its left margin.
The kindlegen tool's CSS parser is sometimes buggy.
As a result, if you have:
div.foo p {
the kindlegen tool often incorrectly interprets it as:
div.foo, div.foo p {
In situations where you want to apply the style to only the inner tag, you must add a custom class to the paragraphs inside the outer tag and use that CSS selector by itself.
For additional tips specific to developing content for KF8-capable readers, see the .
There are many limitations in the MOBI format. A few are listed here.
Blocks of text can never have a greater than normal margin on their right side.
Left margins can only be specified in 1em increments. Text can only have a hanging indent if it has no left margin.
More recent kindle renderers have increased the left margin increment to roughly 2em increments.
Text cannot flow around images taller than one line of text.
Image sizes cannot be scaled with font size.
In some -- but not all -- Mobipocket renderers, text with a left margin changes that margin value per line based upon the font-size at which point the preceding line-break occurred.
Many measures, such as the indent of a hanging indent, cannot be specified in ems.
Individual items of text cannot be displayed in a monospace font.
Tables display wildly differently on different Mobipocket renderers, especially tables which cross more than one screen.
Nested tables are not supported at all.
In addition you only get the full range of Mobipocket's formatting capabilities if you have markup written to use Mobipocket's non-standard, extended, and under-documented implementation of HTML 3.2. See:
on the mobipocket web site.
can optionally be applied to this file format. There is the standard scheme supported by Mobipocket and
servers. This is based on an ID derived from the reading device or program. This PID must be known to the server when an eBook is purchased and will be embedded in the file and locked to the device. The licensing scheme does permit multiple devices (usually up to 4) to be supported. In this case the server needs to know device id of all the devices. If you add a device you must tell the server and redownload the eBook to be able to read it on the new device. Normally there is no charge to add a device or for redownloading the eBook. If the dealer goes out of business you may not be able to add a device since there would be no way to redownload the file.
A second, simpler scheme, only requires knowledge of the account login name and password used to purchase the eBook. Once this data is entered the eBook can be read. Entering this data is only required once per device. This is a new scheme and some readers may not have support for this method.
A third method used on some ebooks is to use a generic MOBI key. It has encryption but only using the generic MOBI key (not a PID-specific key). This means that can be read by any MobiPocket Reader software, on any device, but not by any non-MobiPocket software.
The DRM applies only to the eBook itself and not to the . A library routine can read the metadata without having to unlock the eBook. Some programs have been devised to even be able to change this information without touching the DRM portion of the file.
In addition to the
