CBZ is the ZIP-based counterpart to CBR, used for comic books. It contains a series of image files compressed in a ZIP archive. CBZ files are easy to create and widely supported by comic book reading apps.
AZW3, also known as Kindle Format 8, is a newer eBook format from Amazon. It supports HTML5 and CSS styling, offering enhanced layout and formatting options for Kindle books. AZW3 files can contain both older MOBI content and newer EPUB-like structures for broader compatibility.
Convert your .cbz files to .azw3 right in your browser — no downloads, no installs. Everything happens securely in the cloud.
We never store your files permanently. Only you can access them, and they’re automatically deleted from our servers within 2 hours.
Turn your CBZ files into AZW3 in just a couple of clicks. No registration, no limits — and it’s 100% free.
