How these PDF tools work

Pick a tool, drop in your PDF and download the result. Each tool page explains its options and limits, and after one tool finishes you can send the file straight to the next one, for example compress a PDF and then sign it.

Frequently asked questions

Are these PDF tools really free?

Yes. Every PDF tool on this page is free to use with no sign-up and no watermark. Avalon Pro raises the limits for bigger batches. AI PDF is the one exception: it needs an account and Pro+ credits.

Are my PDF files uploaded?

Most PDF tools run in your browser, so the file never leaves your device. Word, Excel and PowerPoint to PDF can convert on our server for the closest layout, and the file is deleted right after.

Do the PDF tools work on a phone?

Yes. They work in any modern browser on phones, tablets and computers. There is nothing to install.
