Where your file goes

Most PDF websites send your file to their computers to work on it. Astha PDF does the work inside this page instead.

  1. 1

    Your device

    You choose a PDF. It is read from your disk into this page.

  2. 2

    This page

    The tool runs in your browser and builds the new PDF.

  3. 3

    Your downloads

    You save the result. Close the tab and both copies are gone.

Our serversNever receive your file. There is nowhere to upload it to.

Check it yourself

Open a tool, turn off your Wi-Fi or mobile data, and use it. It works the same, because nothing needed to be sent. Read the privacy page

Questions

Is it really free?

Yes. Every tool is free, with no limits and no account. The site is paid for by voluntary donations.

Are my files uploaded anywhere?

No. Your browser opens and changes the file on your own device. Once the site has loaded you can turn off your internet and the tools still work.

Does it work on my phone?

Yes, in any up-to-date browser. Very large files are easier on a computer, because phones have less memory.

What if I make a mistake?

Tools that change your pages have Undo and Redo, and you see the finished PDF before you download it.

Free for everyone. Kept alive by donations.

No ads, no paid plan. If Astha PDF saved you time, you can help keep it running.
