Terms FAQ
What am I responsible for?
You are responsible for the files you convert and for how you use the output. Justvert is provided as-is for media you have the right to process.
Is there a file size limit?
There is no fixed Justvert upload cap because files stay on your device. Very large files are limited by the memory available to the browser. If a conversion runs out of memory, try a shorter clip or a smaller output size such as 720p or 480p.
Does hardware encode always work?
No. Hardware encode depends on the device and the browser. When it is unavailable, Justvert falls back to FFmpeg WASM.
