PDF Reader

View any PDF directly in your browser. Free, private, browser-based PDF viewer with zoom and page navigation — no upload, no signup.

Stays in your browser

Processing runs on your own device. Your files are not uploaded to a server, so private documents stay private.

Open a PDF and read it page by page with zoom controls, right in your browser. It is a read-only viewer, so use PDF Editor if you need to add text and Annotate PDF for notes and comments.

How it works

Upload a PDF and view it directly in your browser — page by page, with zoom controls. The file is rendered entirely on your device using the pdf.js library and is never uploaded anywhere.

Good to know

Works with any standard PDF, including scanned documents.
Use the zoom controls to read small text more comfortably.
Very large files (several hundred MB) may render slowly on phones or older computers.

Troubleshooting

"Could not open this PDF. It may be corrupted or password-protected": If it's password-protected, use Unlock PDF first, then reopen the unlocked file here. If it's corrupted, try Repair PDF instead.
Pages take a long time to render: Very large or image-heavy PDFs are rendered entirely in your browser — a lower zoom level or a faster device will render pages more quickly.
Text looks blurry when zoomed in: This can happen briefly while a page re-renders at the new zoom level — give it a moment, or zoom in smaller increments.
The viewer doesn't remember where I left off: This is a read-only, in-browser viewer without saved sessions — reopening the file starts back at page 1.

Frequently asked questions

No. The PDF is rendered entirely in your browser using pdf.js — it's never sent anywhere.

This is a read-only viewer. For editing, try the PDF Editor tool.

Not directly — unlock it first with Unlock PDF if you know the password.
