About this tool

PDF Viewer — view and read PDFs online, free and private

Open and read any PDF online without an app or a sign-up. The viewer runs entirely in your browser, so no document contents are sent to PaperFit — it just opens, on your device.

How to view a PDF online

  1. Drop your PDF into the box above, or click to choose a file.
  2. The document opens in the viewer — scroll, or use the thumbnail rail to jump to any page.
  3. Search the whole document, select and copy text, and zoom in or out as you read.
  4. No document contents are sent to PaperFit — it opens right on your device, and any copy PaperFit keeps on hand is temporary and clears itself automatically.

What it does

  • Full-document search that finds and highlights text across every page
  • Selectable, copyable text plus zoom and quick page navigation
  • Thumbnail rail to scan and jump straight to the page you need
  • View-only — no sign-up, no watermark

Common uses

  • Reading a contract or report on a shared or work computer without installing a reader
  • Searching a long manual or research paper for one specific term
  • Quickly checking the contents of a PDF before merging, splitting, or sending it

Is it private?

Yes. Unlike most "view PDF online" services, PaperFit processes your file on your device, and no document contents are sent to PaperFit — the viewer opens it directly on your own device using your browser. That matters because the things people read in a PDF are often the most sensitive: a bank statement, a signed agreement, an offer letter, an ID scan. With PaperFit, reading one doesn't mean handing it to a third party. Open your browser's network tab and watch — no document contents are sent to PaperFit while you read.

Frequently asked questions

Are my files uploaded to a server?

No. The PDF opens in your browser. No document contents are sent to PaperFit.

Can I search the text inside the PDF?

Yes. Full-document search scans every page and highlights matches, so you can jump to a word or phrase anywhere in the file.

Can I select and copy text from the PDF?

Yes, on PDFs with real text you can select and copy it. Scanned or image-only PDFs have no underlying text to select.

Is there a file size limit?

You can open PDFs up to 200 MB. Because everything runs locally, very large files depend on your device's available memory.

Does it work on mobile?

Yes. The viewer runs in mobile browsers too, with pinch-to-zoom and the thumbnail rail for navigating long files.

Can I edit or save changes here?

No — this is a view-only reader. To change a PDF, use PaperFit's editing tools like Organize, Split, or Watermark, which also run in your browser.
