About

Pagira

Read full description

Pagira displays your standalone HTML sites, individual HTML pages and your PDFs directly on your iPhone and iPad, even without a connection. Where most readers settle for a rough rendering, Pagira opens a real, complete web folder (HTML, CSS, JavaScript, images, subfolders) and renders it like a browser, locally. WHO IS IT FOR? Pagira is for anyone who needs to read standalone HTML sites, individual HTML pages or PDFs directly on their device, especially offline. Typical uses: - Students whose courses are exported as HTML (medicine, law and other fields), or delivered as e-learning modules. - Technical documentation shipped as a website: electronics, mechanics, engineering manuals, datasheets and reference guides. - Developers and writers previewing static sites and generated documentation (Doxygen, Sphinx, MkDocs, Docusaurus, Storybook, Javadoc). - Reports and exports such as Jupyter notebooks, R Markdown or test reports saved as HTML. - Web pages and articles you want to keep and read later, offline. If your content is an HTML folder, a single page or a PDF, Pagira is built to open it cleanly. FEATURES - Full HTML 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. - Built-in PDF reader: continuous scrolling and automatic scaling, for your local or iCloud PDFs. - 100% offline: once the content is on your device, everything opens without a connection. Perfect on a plane, while travelling or in areas with no network. - Local files and iCloud Drive: open from the Files app, your local storage or iCloud Drive, and also via "Open in Pagira" from other apps. - iCloud on demand: iCloud files are streamed as you go (without downloading everything), or downloaded explicitly for a permanent offline copy, visible in Files. - Reading list: save a page or a PDF for later. Each item is captured as a self-contained snapshot (web archive or PDF copy), so it stays available offline, with read/unread marking. - History: find every page you have viewed, including navigation within a site, grouped by day, and reopen it exactly where you left off. - Recent items: quick access to your most recently opened folders and files. - Auto-reopen: pick up your last reading as soon as you launch the app (can be turned off). - Web archives: open a saved .webarchive file, rendered offline as is. - Universal: built for iPhone and iPad, in both orientations. - Multilingual: available in French, English, 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). After that, a single purchase, with no subscription, unlocks the app for good.

The call
