About Converting TCR to EPUB
TCR is a simple compressed plain-text e-book format from the Psion era. It is obsolete and normally converted to EPUB or TXT. When you need to move away from TCR, the usual reason is simple: obsolete.
Converting your TCR 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 TCR-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 TCR file for the open EPUB standard
- Sharing a TCR 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 TCR files at once; each is processed privately and deleted immediately.

Why choose PrivConvert?
Converting TCR to EPUB should not mean handing a stranger a permanent copy of your data. PrivConvert processes everything in memory and forgets it instantly.
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.
Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.
Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.
Files are processed in volatile memory (RAM) and purged the instant your download is ready — nothing is ever written to disk, cached or backed up.
