Is my .AZW3 file uploaded anywhere?
No. Your .AZW3 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 .AZW3 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.
