About PDF Reader
A Free PDF Reader That Runs in Your Browser
No download. No install. No account. Open a PDF and start reading. OxygenPDF’s free pdf reader loads your document in the browser with a clean reading interface, page thumbnails, zoom controls, and keyboard navigation.
This isn’t a stripped-down preview. It’s a real pdf reader online with fit-to-width, fit-to-page, custom zoom levels from 50% to 200%, fullscreen mode, and a thumbnail sidebar for jumping between pages.
When You Just Need to Read a PDF
Sometimes you don’t need to edit, merge, or convert. You just need to open the thing and read it.
No Software Required
Works in any modern browser. No Adobe Reader, no Preview, no app to install. Just open and read.
Navigate Easily
Thumbnail sidebar for visual navigation, page numbers for direct jumping, keyboard arrows for flipping. Get around fast.
Fullscreen Reading
Expand to fullscreen for distraction-free reading. Toolbar stays accessible at the top, thumbnails in the sidebar.
Works on Any Device
Desktop, tablet, phone. Same reader, same features. No app download required.
How It Compares
There are plenty of free pdf viewers. The difference is whether you need to install something and whether your files stay private.

Read, Then Do Something With It
After reading, you might want to extract pages, rotate something, or add a watermark. The continuation system lets you send your file directly to any other OxygenPDF tool without re-uploading.
Read first, decide what it needs, then act. All in one session, all in your browser.
100% Local Processing
Some PDFs are private. Tax returns, medical results, legal drafts, love letters. The reader runs entirely in your browser. Your file never touches a server.
Close the tab and the data is gone. No cookies, no local storage, no trace.
