the editor

This is what you get

The mousePDF editor with a document open: page thumbnails on the left, the tool rail beside them, and the page rendered in the middle of the workspace.
The actual editor, not a mock-up. The contract in it was made up for the screenshot. Your documents never reach us, so we could not show you one if we wanted to. See how it is built.
The mousePDF editor before a file is opened: an empty workspace with a drop zone in the middle, a keyboard shortcut list below it, and the tool rail down the left edge.
And this is the first screen: no account, no upload dialog, no waiting room. Drop a PDF onto the empty workspace or pick one from your device, and the tools on the left become live.
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.

Use the "Compress PDF" feature in the editor. It's especially worthwhile for image-heavy PDFs, though the pages become images in the process.
