About Converting TXT to EPUB

TXT is unformatted plain text — the simplest, most portable document format. It contains only characters, no styling, and opens instantly everywhere. When you need to move away from TXT, the usual reason is simple: no formatting, images or layout.

Converting your TXT document 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 TXT-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
  • Sharing a TXT document with someone whose software expects EPUB

Tips for best results

  • Files up to 250 MB are supported, and you can batch-convert several TXT files at once; each is processed privately and deleted immediately.

Drag and drop your file into the upload area, click to browse your device, or paste a URL to a file hosted online. You can upload files up to 250 MB and batch convert up to 20 files at once.

2
Automatic conversion

Once uploaded, the conversion from TXT to EPUB starts automatically. The process runs entirely in an isolated environment - your data never leaves the secure pipeline.

3
Download your EPUB file

Your converted file is ready instantly. Click the download button to save it to your device. The file is deleted from memory immediately after download.

A more private way to convert TXT files

Plenty of sites convert TXT files. Very few promise never to keep them — PrivConvert does, and backs it up with how the service is built.

Fast in-memory processing

Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.

Nothing is stored

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.

Isolated sandbox

Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.

No human ever sees it

Your files are handled entirely by automated code. No staff, partner or AI model ever reads, stores or trains on your data.
