Contact
Bugs, format requests, or a file that refuses to convert — all welcome.
Replies usually take a couple of days. There is no support ticket system, no chat widget and no phone number — it is a small project, not a company with a call centre.
Reporting a broken conversion
The most useful report includes:
- The container and codec of the source file (MP4/H.264, MKV/HEVC, and so on)
- Which tool you used and which output you selected
- Your browser and version, and your operating system
- The error text shown in the page, plus anything red in the browser console
Please do not send the media file itself. It is almost never needed, and it is better if it stays on your machine.
Feature requests
Requests that fit the model — something a browser can genuinely do locally — get priority. Anything that needs a server to hold the file, or that would require a paid render farm, probably will not happen.
