Open and read it in your browser, chapter by chapter.
Return later and continue from your saved progress.
Reading experience
- Reflowable text that adapts to your screen and chosen text size.
- Light, sepia and dark themes.
- Your reading progress is saved, so you can resume later.
- Select a passage and use Explain for a plain-language AI explanation of it.
- The reader is text-focused: complex images and layouts may be simplified.
Privacy & AI
The EPUB is opened and processed in your browser, and the file is stored locally. It isn't sent to ReadPro to be read.
If you use Explain, only the passage you select is sent to ReadPro's AI for processing — never the whole file.
Good to know
- Maximum file size is 25 MiB.
- DRM-protected EPUB files are not supported.
- The reader is text-focused, so complex images and layouts may be simplified.
- Your EPUB stays in this browser on this device.
- ReadPro also has an online PDF reader, with the same reader for TXT files.
Questions
Is ReadPro's EPUB reader free?
Yes. Opening and reading your own EPUB is free and needs no account.
Do I need an account?
No. You can open an EPUB and start reading without signing up.
Is my EPUB uploaded to a server?
No. The file is opened and stored only in your browser and is never uploaded. Only a passage you pick for Explain is sent for AI processing.
Does it support DRM-protected EPUB files?
No. EPUB files locked with DRM can't be opened. A DRM-free EPUB works normally.
What happens to images and complex formatting?
The reader focuses on text and reflows it to your screen. Rich images, fixed layouts and complex styling may be simplified or left out.
Can I continue reading later?
Yes. Your progress is saved in this browser. Open the same EPUB again and it resumes from where you stopped.
Can I explain a passage with AI?
Yes. Select text in the reader and choose Explain. A few AI uses are free; after that, ReadPro Pro keeps Explain available.
How do I remove the EPUB?
Open your library and delete it — the document, its bytes and its progress are removed from your browser.
