Terms of use
Short and readable, because there is not much to say when we never receive your files.
Using the site
The converters here are free to use, for personal and commercial work alike, with no attribution required. You may not use the site to process material you do not have the right to process.
Your files are yours
We claim no rights over anything you convert. Since files are not uploaded, we never come into possession of them in the first place.
No warranty
The tools are provided as they are, without any guarantee that they will work for your particular file, produce a specific result, or remain available. Video files vary enormously and some will fail to convert.
Keep your original files. Do not rely on this site as your only copy of anything you care about.
Limitation of liability
To the fullest extent permitted by law, we are not liable for any loss arising from use of this site, including lost files, lost time or lost income.
Open source components
Conversion is powered by FFmpeg, compiled to WebAssembly. FFmpeg is licensed under the LGPL and GPL; the build used here is subject to those licences and the corresponding source is available from the FFmpeg project.
