Pagira opens your HTML sites and pages, your comics in CBZ, CBR, CB7 and CBT, your EPUB books and your PDFs, on iPhone and iPad, even offline. A complete web folder (HTML, CSS, JavaScript, images, subfolders) displays just like in a browser, locally, with no connection. HTML SITES AND PAGES - Full rendering: CSS, JavaScript, images and subfolders genuinely work. fetch/XHR, ES modules and even WebAssembly are supported, because the content is served through a real local web origin, not a simple file preview. - A site in a .zip is uncompressed and opened in one tap. .webarchive files open as they are. - Ideal for courses exported as HTML (medicine, law and other fields) and e-learning modules, technical documentation shipped as a website (electronics, mechanics, manuals, datasheets), generated documentation (Doxygen, Sphinx, MkDocs, Docusaurus, Storybook, Javadoc), Jupyter notebooks, R Markdown and reports saved as HTML, or web pages to keep for later. COMICS AND MANGA - CBZ, CBR, CB7 and CBT, as well as .zip, .rar, .7z or folders that hold only pictures. - Two-page spreads on iPad, manga reading direction, vertical scrolling. - Panel by Panel reading: each panel grows and the balloons read without zooming, even on iPhone. BOOKS AND PDFS - EPUB books with light, sepia and dark themes. - PDFs: continuous scrolling, go to page, contents and thumbnails. - Word, Markdown, RTF and text too. - Highlights, notes and bookmarks in your books and PDFs. SEARCH - Search a whole folder, even scanned PDFs (text recognized on the device), and by file name. - Ask: ask a question, Pagira opens the page that answers it. Nothing made up. OFFLINE AND ICLOUD - 100% offline: once the content is on your device, everything opens without a connection. Perfect on a plane or where there is no network. - Open from the Files app (local storage, iCloud Drive, network server) or via "Open in Pagira" from other apps. - iCloud on demand: files are read as you go, without downloading everything, or downloaded in one tap for a permanent offline copy. Automatic resume after an interruption. - iCloud sync: page, highlights, notes and favorites follow you between iPhone and iPad. HOME AND HISTORY - Home: Currently Reading, Favorites, Recent and Offline, with their covers. - History: every page you have viewed, including within a site, grouped by day, and reopened right where you left off. - Your last reading reopens at launch (can be turned off). Universal (iPhone and iPad, in both orientations) and available in English, French, German, Spanish, Italian, Dutch, Polish and Portuguese. PRIVACY Pagira collects nothing, tracks no one and requires no account. Your files stay on your device and in your iCloud: nothing is sent to a server. No ads, no tracking. TRIAL AND PURCHASE Try Pagira for free with all its features (up to 20 document openings, opening a folder doesn't count). After that, a single purchase, with no subscription, unlocks the app for good: Pagira Pro, or Pagira Pro Supporter, shared with your whole family.

Verdict

The call
