Reporting a problem

Because every file is processed inside your browser, we never see what went wrong on your side. These details let us reproduce it:

Which toolFor example "Compress PDF with the Under 100 KB target".
Your device and browserFor example "Android 14, Chrome" or "Windows 11, Edge". Older phones and in-app browsers (inside Instagram or WhatsApp) behave differently from a normal browser.
What you expected and what happenedCopy any message the tool showed, word for word.
The kind of filePage count, rough size, and whether it is a scan or a typed document.

Please do not email confidential documents. If you can, recreate the problem with a dummy file, or describe the file instead.

Feature requests

Tell us the job you were trying to get done, not only the feature. "I need to put a 20 KB signature into a form" is more useful than "add resize", because it shows which settings matter.

Business enquiries

For partnerships, advertising or anything else, use the same email address and mention "Business" in the subject line.

Privacy questions
