PDF Reader

A fast, distraction-free viewer for when the built-in one will not do: full-text search, thumbnails, an outline sidebar, night mode and continuous or single-page scrolling.

Runs in your browser — files never leave your device.

About PDF Reader

Some environments — locked-down work laptops, kiosk browsers, old tablets — have no working PDF viewer, or one that cannot search or show bookmarks. This page renders the file with a complete PDF engine inside the browser.

Because the file is read locally and never uploaded, it is also a safe way to open a PDF you do not fully trust: no scripts run, no external links are fetched automatically.

How it works

  1. Drop PDF file onto the box above, click it to browse, or paste from the clipboard.
  2. Check the file list; remove anything you added by mistake.
  3. Press Convert. The work happens on your device, so speed depends on your computer or phone.
  4. Download the result.

About the format

PDF · Portable Document Format · .pdf

The fixed-layout document standard: looks the same on every device and printer, which is why forms, invoices, contracts and reports are shared as PDF.

  • A PDF can contain vector text, embedded fonts, images, form fields, annotations and digital signatures.
  • Scanned PDFs are just pictures of pages; they need OCR before the text can be searched or copied.
  • PDF is an open ISO standard (ISO 32000) since 2008.
