Frequently asked questions
Why flatten a PDF?
So the filled-in answers, highlights and stamps can’t be changed, and look the same in every viewer and printer.
Are links kept?
Yes, clickable links are kept unless you turn that off under “More options”.
Are my files uploaded to a server?
No. This tool runs entirely in your browser, so your files stay on your device and are never sent anywhere. It even works with the internet switched off.
Is it free, and are there limits?
It is currently free, with no sign-up, no daily limit on files and no watermark added to your results.
