FAQ
Specifics for this converter
What is a CBZ file (comic book archive)?
CBZ is a Comic Book Archive (Comic Book ZIP): it’s basically a ZIP file full of page images with a .cbz extension so comic reader apps open it like a book.
How do I make sure the page order is correct?
Most comic readers sort pages by filename. Use zero‑padded names like 001.jpg, 002.jpg, 010.jpg. When you build a CBZ here, we also prefix pages (001-, 002-, …) to keep your chosen order.
Why do I sometimes see “extra images” like __MACOSX or ._ files?
Those are macOS ZIP metadata files (resource forks). They can look like .jpg files but they are not real pages. Our ZIP to CBZ converter ignores them.
Which image formats are supported?
Common comic page image formats work best: JPG/JPEG, PNG, WEBP, GIF, BMP, and AVIF. Your ZIP must contain at least one real image file.
Does ZIP to CBZ change or re-encode my images?
No. We don’t re-encode images. We rebuild the CBZ archive in your chosen order using the original image bytes.
Is ZIP to CBZ conversion private?
Yes. Everything runs client‑side in your browser — your ZIP is not uploaded to a server.
