Frequently asked questions
Is my video uploaded to a server?
No. Analysis, preview and processing use the video in your browser. A report and optional sample are sent only after you explicitly choose and authorize them.
Which videos are supported?
MP4, MOV or WebM, up to 40 MB and 4 million pixels per frame. One video track. Support depends on the file’s codecs and your browser. Protected files are rejected. Check the result before use.
Which audio will be extracted?
We use the primary mono or stereo track at 8–48 kHz. Output is at 44.1 kHz: 16-bit PCM WAV or lossy MP3. Gaps in the audio may become silence. Videos without an audio track are rejected.
Does extraction restore audio quality?
No. WAV may be larger, and MP3 adds lossy compression and a little padding. Conversion does not restore lost information.
Is there a duration limit?
There is no fixed limit in minutes. We accept videos up to 40 MB within the listed format and resolution limits. Processing has a 90-second time limit and can be cancelled; long or complex videos may exceed your device’s resources.
What is the extracted audio size limit?
Extracted audio can be up to 40 MB. WAV files may be larger; choose MP3 or a smaller video if you reach the limit.
