How PDF Tool works

  1. Choose a tool

    Pick one of the 41 tools above, for example to merge, compress, convert or sign a PDF.

  2. Add your file

    Drop the file into the page. Your browser reads it into memory on your own device – nothing is sent to a server.

  3. Download the result

    Your device creates the new file and your browser saves it straight to your downloads. Close the tab and the data is gone.

Limits and good to know

  • Files up to 100 MB each, and up to 20 files at once in tools such as Merge PDF.
  • Speed depends on your device: very large or scanned PDFs take longer on older phones and laptops.
  • No account, no watermark and no daily limit. All tools are free to use.
  • PDF Tool runs in current versions of Chrome, Edge, Firefox and Safari and can be installed as an app.

Frequently asked questions

Are my files uploaded?

No. Every tool processes your files with code that runs in your browser. You can check this yourself in the “Network” tab of your browser’s developer tools.

Is PDF Tool really free?

Yes. All tools can be used for free, without sign-up and without a watermark on the result.

Does it work on my phone?

Yes. The tools work in mobile browsers on Android and iOS. Very large files are processed faster on a computer.

What happens to my files after processing?

They only exist in your browser’s memory while the tab is open. PDF Tool has no server that could store them.
