privacy
Your files never leave your browser.
Other PDF services upload your document to their servers. mousePDF doesn't: all the editing happens locally on your device – no upload, no storage, no third-party access to your files. The site itself is ad-funded; with your consent, that means cookies are used – your documents aren't affected. 100% free and with no limits.

faq
Frequently asked questions
Is mousePDF really free? +
Yes. Every feature is free to use, with no trial period, no limits and no watermarks. If the tool helps you, we'd be glad of a small voluntary donation when you save.
Are my files uploaded anywhere? +
No. Editing runs entirely in your browser. Your PDFs are never sent to or stored on a server.
Do I need an account or to sign up? +
No. You can start right away: no email, no registration, no login.
What features does the editor offer? +
Add text and images, draw and highlight, sign, reorder, rotate and delete pages, merge PDFs, split a PDF, add a watermark, shrink a PDF, set and remove passwords, convert PDF ⇄ Word and images ⇄ PDF, and export without watermarks. Plenty of features that normally cost money elsewhere.
How do I merge multiple PDF files for free? +
Open a PDF in the editor, choose "Merge PDFs" from the menu, and attach more files, or insert one at a specific page. Runs entirely in your browser, no upload, no limit on the number of files.
How do I compress a PDF file? +
Use the "Compress PDF" feature in the editor. It's especially worthwhile for image-heavy PDFs, though the pages become images in the process.
How do I sign a PDF online? +
With the sign feature, right in your browser: draw a signature with your mouse or finger, type it as text, or use a photo of your own signature, then place it anywhere in the document. No account, no upload.
Does this work on mobile too? +
Yes, mousePDF runs in any modern browser on desktop, tablet, and smartphone.
What languages is mousePDF available in? +
The interface is available in 41 languages, pre-selected based on your browser language, including German, English, Spanish, French, Arabic, Chinese, Japanese, Korean, Hindi, Punjabi, Thai, and many more.
