CAJ to PDF

A CAJ paper arrives on your phone or iPad, and your computer is nowhere near. "I'll convert it when I'm back at my desk" usually means it never gets converted. This app puts that step in your hands: pick the file, and it takes care of the rest. 【What it does】 · Converts CAJ / KDH / NH files to PDF · Select several files at once — they convert one by one in the background, with visible progress · Export or share the results, or save them to Files 【Why convert on your phone】 · Everything happens on your device — files are never uploaded and never pass through any server, so unpublished manuscripts and confidential material are safe to handle · No internet required; it works on a plane, or in a lab with no connection · Universal across iPhone and iPad; the two-column layout gives you more room in iPad landscape · Supports common CAJ files; results depend on the structure and quality of the source file itself · For pages that are pure scanned images, the app performs no text recognition (OCR) — those pages stay as images · Some files with unusual encodings contain no finished page layout, so the positions of text and images are inferred by the app and may differ from the original. When it encounters such a file, the app tells you so honestly before converting 【Pricing】 · Converts 5 files per day for free · Need more? A subscription unlocks unlimited conversions — weekly, monthly, or yearly · Subscriptions are billed through your Apple ID and can be cancelled anytime in your App Store account settings 【Before you use it】 Please only process files you have lawfully obtained and have the right to convert, and use them for lawful purposes such as personal study, research, or backup. This app performs only public, reversible format conversion; it does not remove protection from any password- or permission-protected file.
