The short version

What is Online PDF Reader?

Online PDF Reader is a free tool that lets you read PDF documents directly in your web browser without installing any software.

Upload a PDF and browse through pages with smooth navigation, zoom in and out for detail, search for specific text across all pages, and use fullscreen mode for comfortable reading. Keyboard shortcuts (arrow keys, Ctrl+F) make navigation fast. Everything runs client-side — your files stay on your device.
