Ask for something
Missing a tool, a format, or found something broken? Say so. This is a one person operation, so the list of what to build next is mostly other people's requests.
The request
This goes in your own mail app, not into a form on this page. Leave it out and the message is still perfectly readable.
Write a sentence or two first, and the buttons wake up.
Where this goes
Nowhere, until you send it. There's no form handler behind this page and no third party collecting anything. The message is assembled in your browser and handed to your own mail app, which is the same arrangement as everything else here: the work happens on your device.
If you would rather not use a mail app, copy the message and send it however you like, to [email protected].
Worth checking first
There are more tools here than the front page shows. The image tools cover crop, resize, compress, blur, redact and a good deal more, PDF tools handle merging and splitting, and video converts between MP4, MOV, MKV, AVI and WebM. Both tool hubs have a search box.
