What is a .CBT file?
CBT is a TAR archive of comic page images.
- Did you know
- CBT packs comic pages into a TAR archive instead of a ZIP.
- The trailing letter of a comic archive names its format, so CBT stores comic pages in an uncompressed TAR archive.
- TAR keeps no central index, so a CBT reader has to walk through the whole file to list every page.
- 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
- .CBT 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 .CBT file
- Drag a .CBT 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.
