What is a .IBOOKS file?
The .ibooks format came from Apple’s iBooks Author for interactive textbooks. Created by Apple.
- Did you know
- iBooks Author let teachers build rich interactive textbooks for the iPad.
- The .ibooks format was built on EPUB but extended with Apple’s interactive widgets such as galleries, quizzes and embedded media.
- Apple retired iBooks Author in 2020 and folded its book-making features into the Pages app.
- 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
- .IBOOKS 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 .IBOOKS file
- Drag a .IBOOKS 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.
