PDF Viewer
Open and read any PDF in a clean, ad-free viewer.
Open a PDF in your browser without downloading anything or bouncing to a heavy app. Continuous scroll, thumbnail sidebar, keyboard shortcuts, search and dark mode – the basics done right.
How it works
Four calm steps.
- 01
Drop your file
Drag the PDF you want to read onto the upload card, or click to pick it from your device. You can also paste a link to a file hosted online.
- 02
Navigate
Scroll, use the thumbnail sidebar, or jump to a page number. Ctrl+F searches inside the document.
- 03
Adjust for comfort
Toggle dark mode, single-page or two-up view, and rotate temporarily without editing the file.
- 04
Move on
Download the file if you'd like, or drop a different one. Nothing is uploaded permanently.
Why PDF Viewer
Built to be the last pdf viewer tool you try.
No overlays, no upsells, no 'download our extension' banners.
Streams pages on demand so a 500-page book opens in a second.
Uploads travel over TLS, files are encrypted at rest, and every trace is deleted within 60 minutes. We do not read, index, or train on your documents.
The free tier handles most day-to-day work. You only create an account if you want history, larger files, or batch automation.
