Contact
A real person reads these. Replies usually take a couple of days.
There is no contact form here, and that is deliberate: a form would need a server to receive it, and this site does not run one. Email keeps the promise on the rest of the site intact.
What to write about
Something is broken
Tell us which tool, which browser, and what the file was — format, rough size, and roughly how long if it's a video. That is usually enough to reproduce it.
A tool you wish existed
Especially if you keep hitting a sign-up wall somewhere else. Those requests go to the front of the queue, because they are the reason this site exists.
An ad in the way
Ads should never obstruct a tool. If one does, that is a bug — tell us where you saw it and on what device.
Privacy questions
Happy to explain exactly what does and does not happen to your files. See the privacy policy for the current answer.
Please don't send us your files
If a tool fails on a particular file, describe it rather than attaching it. We do not want a copy of your document, and the whole point of this site is that we never receive one — it would be strange to break that in a support email.
The format, the approximate size, the browser you used and any message the tool showed are almost always enough to find the problem.
