About PDF Viewer
Open a PDF in your browser without Adobe Reader. Pages are drawn sharply at any zoom level, long documents load page by page so they open quickly, and you can go full screen, print or download the file. Password-protected PDFs open after you type the password. The PDF is shown on your device with pdf.js and is never uploaded. Need to change something? Jump straight to our PDF editor, sign the PDF, or convert it to Word, JPG or Excel.
Frequently asked questions
Is it free?
Yes – free with no sign-up, no ads in the viewer, no watermark and no limit on how many files you open.
Is my file uploaded?
No. The file is opened and shown on your device and never leaves it. Only formats a browser can't read (old .doc/.ppt/.xls, Pages, Keynote, DjVu, XPS, MOBI) are converted once on our server over HTTPS and deleted right away – the page tells you when that happens.
Can I open a password-protected PDF?
Yes. Type the password when you are asked – it is used only in your browser. To remove the password for good, use Unlock PDF.
Can I edit or sign the PDF?
Yes. Click Edit to open the PDF in our PDF editor (add text, change existing text, highlight, draw) or use Sign PDF.
Do I need to install anything?
No. It works in any modern browser on Windows, Mac, Linux, Chromebook, iPhone and Android. On Android you can also install the free Kitbly app and pick it in “Open with”.
Does it work on my phone?
Yes. It works in any modern browser on iPhone, Android, Windows and Mac.
