Questions, answered

Can I read an EPUB file online?

Yes. Select a DRM-free EPUB file and Readlyst opens it directly in your browser without requiring an account or software installation.

Is my EPUB uploaded to a server?

No. The file is processed locally by your browser and is not sent to Readlyst or stored online.

Does this reader support DRM-protected ebooks?

No. DRM-protected files from some ebook stores cannot be opened. Use a DRM-free EPUB that you own or have permission to read.
