What is a .CB7 file?
CB7 is a 7-Zip archive of comic page images.
- Did you know
- CB7 uses 7-Zip compression to pack a digital comic.
- The comic-archive naming convention encodes the underlying archive in its last letter, so CB7 is simply a 7-Zip archive of page images.
- CB7 is rare in practice, with most digital-comic collections settling on the ZIP-based CBZ instead.
- What Analyser reads
- Open documents, ebooks and publishing files beyond Office: comic books (CBZ/CBT with ComicInfo + first-page preview; CBR/CB7 identified), Microsoft XPS, FictionBook FB3, iBooks, Scrivener, Visio VSDX, R Markdown/Quarto, RTFD, WARC/MAFF web archives, TeX DVI, legacy Hangul HWP, and WordPerfect/QuarkXPress/PageMaker identification.
- Depth of analysis
- .CB7 is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .CB7 file
- Drag a .CB7 file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
