About CBR

Comic Book RAR — images in a RAR.

CBR is the RAR-based sibling of CBZ — a comic book whose pages are JPEG/PNG/WebP images bundled inside a RAR archive. We unpack the RAR with libarchive compiled to WebAssembly, sort pages with natural ordering (so page2.jpg comes before page10.jpg), and stream each image to a paginated reader. Keyboard ←/→ flip pages; tap or click the left/right half of the page to do the same on touch.

FAQ
Why is it slower to open than a CBZ?
RAR — especially v5 with solid compression — has to decompress a contiguous block before any single page is available, so the initial extract is heavier than a ZIP. Once unpacked, page flips are instant. If the file is huge, give it a few seconds.
Is my file uploaded?
No. The CBR is unpacked entirely in your browser inside a WebAssembly worker. Nothing is sent to a server.
Password-protected CBRs?
libarchive supports encrypted RARs but we don't expose a password prompt yet. If your archive is encrypted, extract it first with WinRAR / 7-Zip and load the resulting CBZ.
Does it work on mobile?
Yes. The viewer is mobile-first — keyboard shortcuts on desktop, tap-to-turn on touch, and a page slider on screens wide enough to fit one.
