Information about MOBI and PDB file formats

Full name MOBI - Mobipocket PalmDOC eBook File
File extension .mobi, .prc .pdb
MIME type application/x-mobipocket-ebook application/vnd.palm
Developed by Mobipocket SA Palm, Inc.
Type of format Ebook file format eBook File
Description The MOBI file extension was created in 2000 by Mobipocket. This company produced Mobipocket Reader applications for computers and smartphones. In 2005, Amazon bought Mobipocket. As a result, MOBI files are identical to Amazon's AZW format for Kindle devices. The .pdb file extension is a database format used for the Palm OS platform. The PalmDOC eBook file type is a version of the PDB format. Unfortunately, the proliferation of eBooks has left this format behind due to the lack of support for DRM protection, meaning only royalty-free text is typically available.
Technical details The Mobipocket ebook format is based on the Open eBook standard using XHTML and can include JavaScript and frames. It also supports native SQL queries to be used with embedded databases. The Amazon Kindle's AZW format is just the Mobipocket format with a slightly different serial number scheme, and .prc publications can be read directly on the Kindle. The Kindle AZW format also lacks some Mobipocket features such as JavaScript. The format supports reflowable content; however, the format lacks some of the features found in more modern eBook formats, for example, only providing an entire contents table. In addition, the format features RLE compression, which was crucial because the format was designed for the low storage capacity Palm devices of the 1990s.
