Convert WEBP files to CBZ free in your browser — no signup, no install, and the file is never uploaded to a server. CBZ keeps full quality with no further loss.
Add your WEBP file
Drag the WEBP file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
Confirm CBZ as the output
CBZ is already selected as the output format on this page. Only the options this format actually supports show up, such as a page range or sheet selection.
Run the conversion
Press the convert button. Processing happens on your own device, so the time depends on your computer rather than a server queue.
Download the CBZ file
When it finishes, download the CBZ file. Converting multiple files gives you the option to download them together as a ZIP.
Google's image format, typically 25-35% smaller than JPEG at equal quality. It supports lossy, lossless, transparency, and animation, though some older software cannot open it.
A comics format that is simply a ZIP of image files with a renamed extension. Dedicated viewers display the images in page order.
Yes. WEBP to CBZ conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
No. The conversion runs entirely inside your browser using WebAssembly, so the WEBP file never leaves your device. That is also why it works without an internet connection once the page has loaded.
No — CBZ has no alpha channel, so transparent pixels are replaced with a solid background. If transparency matters, convert to PNG or WebP instead.
CBZ stores a single frame, so only the first frame is kept. To preserve motion, convert to an animated format such as WebP or MP4.
It can go either way. Both formats are lossless, so nothing is thrown away — the size difference comes from how each one packs the same data.
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
