What is a .PRC file?
The open standard for reflowable e-books.
A .prc file is almost always a Mobipocket ebook, structurally the same as a .mobi file but with an older Palm OS extension. Open DRM-free files with Calibre (free, all platforms). Amazon-purchased books need the Kindle app. Amazon stopped accepting MOBI/PRC in Send to Kindle in 2022, so converting to EPUB is the practical option for current readers.

Is my .PRC file uploaded anywhere?
No. Your .PRC file is unpacked and displayed for you. Your reading position is remembered for next time.
Can I read Kindle books bought from Amazon?
Only if they're DRM-free. Most purchased Kindle books are copy-protected, and we don't remove DRM. The reader tells you when a file is protected.
Why does my .PRC file look different from the publisher's layout?
For comfortable reading we apply our own typography and drop the file's scripts and most of its styling. Text, headings, images, tables and links are kept.
Can I read comics and manga?
Yes. CBZ and CBT open directly, CBR and CB7 through our archive engine. Switch between single and double pages, fit to width or height, and turn on right-to-left reading for manga.
What about PDF books?
Use our PDF Viewer. It has thumbnails, zoom and full-text search.
