CHM eBook Format

CHM Converter

Microsoft Compiled HTML Help files use the extension .chm. They contain compressed help documentation in an HTML format that can open in web browsers and Microsoft HTML Help Executable. Like other HTML files, CHM files can contain images as well as text and links. Previously, CHM files were quite common as download links on websites; however, they could be vulnerable to hackers. Microsoft has also confirmed that it will not be adding any extra features to Help.

For security and accessibility, most websites now have help sections using search functions or dropdown FAQs rather than needing additional downloads. While you can open CHM files with an internet browser, most companies advise caution unless the source is trusted. However, Microsoft programs still use the format and you can open a CHM file on a Windows computer by double-clicking on the file. The CHM format is also sometimes used now for ebook files, and you can open this type of CHM file with Calibre’s ereader software.

PDB eBook Format

PDB Converter

The PDB format name is short for Palm Desktop Database. Palm was a popular personal desktop assistant (PDA) brand from the mid-1990s up until 2011. PDAs like Palm and BlackBerry were a precursor to smartphones. There were several programs on Palm devices which used the PDB format, including word processors, database or spreadsheet applications, and the Palm ereaders. You can find out what type of program a PDB was created with by opening the file in a text editor.

As smartphones have now replaced PDAs, people tend to use these or a separate ereader for reading ebooks. The PDB format also didn’t have digital rights management (DRM) for authors and publishers to copy-protect their work. While Palm devices are no longer being sold, you can still get the Palm Desktop application for Windows. Other ways of viewing PDB files include with Calibre’s ereader software, or with the XnViewMP graphics application.
