What is a .CBZ file?
The open standard for reflowable e-books.
A CBZ file is a digital comic book: a ZIP archive holding the comic's pages as JPEG or PNG image files named in reading order. Open it with a free comic reader - YACReader on any desktop, CDisplayEx on Windows, MComix on Linux. Because it is a plain ZIP, you can also rename it to .zip and open the pages with any archive tool.

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