Online PDF Viewer - Free Online Browser Tool

Read and view PDF documents securely in browser with zoom and page controls.

A document viewer that opens files locally instead of streaming them from a server. Everything happens in the tab — page navigation, zoom, text selection, printing — so nothing about the document or where you found it is disclosed to a third party.

This online pdf viewer utility runs completely inside your web browser. Your document is opened locally and processed on your own device using JavaScript and WebAssembly, so your file is never uploaded to any server. There is no signup, no watermark and no limit on how many documents you can handle.

  • 100% client-side - files never leave your device
  • Instant processing, no upload wait
  • Works on desktop, tablet and mobile
  • Free forever, no account required

How to Use the Online PDF Viewer Tool

Four steps, and the whole thing runs locally on your own device.

  1. Open a PDF

    Drop a file onto the viewer or browse for one. It renders locally in the tab.

  3. Use the viewing controls

    Fit-to-width, fit-to-page, single and continuous page views, plus page jump and search.

  4. Print or close

    Send the document to your browser’s print dialog, or close it without having contacted any server.

Frequently Asked Questions

Does viewing a PDF here expose my IP to the document’s source?

No. Once the page has loaded, the document is read entirely from your device. The origin site never learns that you opened the file.

Will large documents be slow to open?

Page rendering takes a moment per page on a large file, which is normal for any client-side PDF engine. Progress is shown as pages render.

Can I search for text in the document?

Yes, and search works on the text layer, so it finds terms anywhere in the document and jumps to the right page.

Is the document uploaded for viewing?

No. The file is opened directly by the browser from your device, which is the whole reason this viewer exists.

Can I open a document from a phone?

Yes, browsing for a file works on mobile, and touch gestures handle panning and zooming.
