Output files are limited to 256MB. Use a lower bitrate for longer files. Processing support and speed depend on your browser and device.

Compression time limits: 1 minute for a 5-second sample, 5 minutes for full audio and 10 minutes for full video. Operations stop when the limit is exceeded.

Selected bitrates are ceilings and are reduced automatically to fit the original size. Full results can be saved only when smaller than the original. Check playback before saving. Only primary video/audio tracks are saved; subtitles and descriptive metadata are excluded.
