About this tool

PDF Reader opens documents instantly in your browser — no upload, no account. Scroll through pages continuously, jump with thumbnails or the document outline, and zoom from 50% to 400% or fit the page to the window.

Search finds every occurrence of a word and highlights it on the page; step through matches with Enter. Internal links jump to their target page, and external links open safely in a new tab (unsafe link types are blocked).

Print renders pages to images locally and sends them straight to your printer. Keyboard shortcuts: ←/→ or PageUp/PageDown to change pages, +/− to zoom, 0 to fit width, R to rotate, Ctrl+F to search.
