Information about PDB and AZW3 file formats

🔸 File format PDB AZW3
🔸 Full name PalmDOC eBook File Amazon KF8 eBook File
🔸 File extension .pdb .azw3
🔸 MIME type application/vnd.palm application/octet-stream
🔸 Developed by Palm, Inc. Amazon
🔸 Type of format eBook File
🔸 Description 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. AZW3 - Kindle Format 8 (KF8) is Amazon's newer version of AZW. It supports HTML5 and CSS3, which were not supported through the standard AZW format. In addition, it has several other formatting options and is used by Amazon for all new Amazon eBooks. It is supported by fourth-generation Kindle devices running firmware version 4.1.0 or later and the Kindle Fire device.
🔸 Technical details 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. KF8 (also called AZW3) is essentially a compiled ePub that has utilizes a Palm database and Amazon's DRM scheme. It targets ePub 3 version support, but existing ePub can also be used. The internal format has been decoded using mobi_unpack. However, the basic format remains as a PDB file similar in structure to a MOBI. Thus, more often than not, a KF8 file will contain both a MOBI file at the beginning and the newer KF8 version of ePub later.
