About this tool
Open a PDF and read it without installing Acrobat or handing the file to a website. Drop the PDF in and every page renders on the page, with a zoom control for the fine print. Because it uses your browser’s own PDF engine, the document is opened entirely on your device — nothing is uploaded, which makes it private and quick. It’s the fast way to glance at a PDF someone sent you, or to read one on a computer that doesn’t have a PDF app set up.
What people use it for

- Read a PDF on a locked-down or shared computer
Frequently asked questions
No. It’s opened and rendered entirely in your browser using its built-in PDF engine, so the file never leaves your device.
Yes — there’s no fixed cap; it’s bounded by your device’s memory. Very large or image-heavy PDFs take a moment longer to render.
Yes. Open Advanced options for a zoom slider to enlarge pages for small print.
Yes, it renders the pages as they are — including scans. It displays them rather than extracting text (use the OCR tool to pull text from a scan).
Encrypted PDFs need their password to open and that isn’t handled here; remove the password first with the Unlock PDF tool if you have the rights to.
Yes — a client-side tool, no account, no limits, nothing stored.
