About Converting PDB to EPUB
PDB is an old Palm OS database format that was used for e-books on Palm devices. It is largely obsolete and usually converted to EPUB. When you need to move away from PDB, the usual reason is simple: obsolete.
Converting your PDB e-book to EPUB solves that. EPUB is the open, reflowable e-book standard used by most readers except Kindle. Text adapts to any screen size, and the format supports images, styling and navigation. In practice you gain reflowable text for any screen and open standard. PrivConvert runs the whole PDB-to-EPUB conversion in server memory and deletes your file the instant the EPUB is ready — nothing is stored, logged or reused.
When this conversion helps
- You need reflowable text for any screen
- You need open standard
- You need supported by most e-readers and apps
- Escaping a proprietary PDB file for the open EPUB standard
- Sharing a PDB e-book with someone whose software expects EPUB
Tips for best results
- Files up to 250 MB are supported, and you can batch-convert several PDB files at once; each is processed privately and deleted immediately.

What makes this PDB-to-EPUB converter different
Privacy here is not a checkbox. Every PDB-to-EPUB conversion is engineered so your data never lingers, leaks or gets reused.
Convert instantly with no sign-up, no email and no profiling cookies. We never build a profile around you or the files you convert.
Runs in any modern browser on Windows, macOS, Linux, Android and iOS — no install, plugin or desktop software needed.
Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.
We never keep a copy. Once your EPUB is delivered, both the original and the result are gone — there is nothing left to leak or misuse.
