Real File Viewer

Privacy Policy

Last updated: September 5, 2026

The short version

Real File Viewer never receives, stores, or transmits the contents of any file you open. Every viewer on this site — PDF, DOCX, XLSX, PPTX, images, HEIC, CSV, JSON, code, archives, audio, video, and EPUB — runs entirely inside your browser using WebAssembly and JavaScript. There is no upload step, no server-side processing, and no database that ever sees your file.

What we don't collect

We don't collect, log, or have any technical means of accessing:

  • The contents of any file you open, view, or convert
  • Filenames or file metadata
  • Account information — there are no accounts

What limited data is collected

Like most websites, standard, aggregated analytics (such as page views) and advertising (via Google AdSense) may use cookies or similar technology to serve ads and measure site traffic. This data relates to your visit to the site, never to the contents of files you view — those never leave your device to begin with.

GDPR & international users

Because no file data is ever transmitted to us, there is no file-related personal data for us to process, store, or be asked to delete under GDPR, CCPA, or similar regulations. Any advertising cookies are subject to your browser's and, where applicable, our consent banner's controls.

Local storage & offline use

If you install Real File Viewer as an app (PWA), your browser caches the site's own code so it can run offline. This cache contains our application code only — never your files. Files you open are held only in your device's working memory and are cleared when you close or reload the tab.

Third-party links

Pages on this site may link to third-party resources (for example, the open-source libraries that power each viewer). We aren't responsible for the privacy practices of those external sites.

How this is actually private

Not just a badge — here's exactly how, so the claim is verifiable.

100% Private

Files never leave your device. There is no server that ever receives your file's contents.

No Uploads

Every format is decoded and rendered locally via WebAssembly or JavaScript. Open your browser's Network tab and confirm nothing is sent.

No Storage

Nothing is written to a server or database. Memory clears the moment you close or reload the tab.

GDPR-friendly by design

There's no file data collection to comply with in the first place — no account, no tracking of file contents, no analytics on what you view.

Verify it yourself: open DevTools → Network tab before opening a file. No request fires with your file's contents — ever.
