Frequently asked questions

Are my files uploaded to a server?
No. Your files are read directly in your browser and never leave your device — the book itself is never uploaded or stored. If you are signed in on Pro, Sync saves your reading position, highlights and notes to your account so they follow you between browsers; see the privacy policy for exactly what that covers.
What are the file size limits?
The reader runs entirely in your browser, so there is no upload and no tier limit — free and Pro read the same files. Above 30 MB we warn you first, because the whole book is held in your browser's memory; you can open it anyway, or compress or split it first.
Does the reader support table of contents?
Yes. For EPUB files, the table of contents is automatically extracted and displayed in a sidebar. Click any chapter to jump to it.
Can I change the reading theme?
Yes. The reader supports three themes: Light, Dark, and Sepia. Click the theme button in the toolbar to cycle through them.

On Android, the Epublys app reads EPUB and PDF offline and runs the EPUB and PDF tools on the phone, with nothing uploaded. Free on Google Play.
