Comic Converter — CBZ / CBR ↔ PDF, Offline
Drop a CBZ, CBR or CBT comic archive and convert it to a PDF, repack it as a different archive type, or build a comic from a folder of images. Reorder pages before you save. Runs entirely on your machine — no upload, no file-size limit, no watermark.
How to use it
- Drop a CBZ, CBR or CBT archive (or a folder of page images) onto MiniMax Converter.
- Pick the output format in the format chooser — PDF for a readable document, or CBZ/CBT to repack.
- Reorder the pages if needed so they're in the right reading sequence.
- Choose where to save and the converted comic is written locally.
What you get — and what it can't write
MiniMax Converter reads CBZ (zip), CBT (tar) and CBR (rar) comic archives and turns them into a PDF, or repacks between archive types. It also bundles a folder of loose images into a CBZ or CBT. One honest limitation: it does not write CBR, because RAR creation isn't freely licensed — so a CBR comes out as CBZ or CBT instead. CBR reading needs 7-Zip installed (the app prompts you if it's missing). Page images are copied straight through, so the picture quality inside the archive is never re-compressed.
PDF, repack, or build from a folder
Drop a CBZ/CBR/CBT and choose PDF to get a flat, readable document where every page is one image — handy for tablets, e-readers, or printing. Go the other way and a PDF becomes a comic archive: each page is rendered to a PNG at 2x scale and packed into CBZ or CBT. Building from scratch? Drop a folder of images and they're sorted in natural page order (page2 before page10), renumbered page_0001, page_0002… and zipped into an archive. You can reorder the pages before saving so the sequence matches the read order you want.
Why offline?
Comic archives are big — a single scanned volume runs hundreds of megabytes, and online converters cap uploads (often 100 MB), throttle you, and may add ads or watermarks. Worse, you'd be handing your library to a stranger's server. MiniMax Converter does everything on your machine: no upload, no file-size limit, no watermark, no telemetry. A whole shelf of comics converts at local-disk speed and never leaves your computer.
Questions and answers
Can it create a CBR file?
No. It reads CBR (with 7-Zip installed) but does not write CBR, because RAR creation isn't freely licensed. Output archives are CBZ or CBT instead, both of which any comic reader opens.
Does converting to PDF lose image quality?
When you convert an archive to PDF the original page images are placed into the PDF without re-compression, so quality is preserved. Going from PDF to a comic archive does re-render each page to a PNG image at 2x scale, since a PDF page isn't already a single picture.
Can I reorder the pages or fix the order?
Yes. Pages from a folder or archive are sorted in natural order (so page2 comes before page10, not after), and you can reorder them before saving so the final archive reads in the sequence you want.
Can I turn a folder of scanned images into one comic file?
Yes. Drop a folder of JPG, PNG, WEBP, GIF, BMP or TIFF images and they're packed in page order into a single CBZ or CBT archive, renumbered automatically so readers show them in sequence.
