Are my files uploaded?

No. Conversion runs in your browser. Your files never leave your device.

CBZ is images in a ZIP folder. CBR is the same idea but in a RAR archive. Both are supported; CBR uses WebAssembly (unrar) loaded from your site.

What image formats work?

JPG, PNG, GIF, WebP, BMP, TIFF, AVIF, HEIC/HEIF, and more—anything the browser can decode is turned into PDF pages.

Multiple comics at once?

Yes. You get a ZIP file with one PDF per archive.
