Open and read a PDF instantly in your browser. Zoom, scroll through pages, and view without installing anything. Your file is never uploaded.
Sometimes you just need to quickly check what's inside a PDF without downloading a dedicated reader app or waiting for a slow desktop program to open. This viewer renders any PDF instantly in your browser tab.
Built on Mozilla's PDF.js — the same open-source engine used inside Firefox's built-in PDF viewer — pages render directly on an HTML canvas. Nothing is uploaded; the file stays in your browser's memory the entire time, which matters when you're previewing something private before deciding whether to share it.
Choose your PDF file in the tool and it opens instantly in the browser viewer. No Adobe Reader or any other app needed — works on any device with a browser.
