Frequently asked questions
What video formats are supported?
Common formats including MP4, WebM, MOV, AVI, and MKV are supported. Support may vary slightly by browser due to codec availability.
Will the audio quality be the same as the original video?
The extracted audio quality depends on the original video's audio bitrate. If you select MP3 as output, you can set the bitrate; selecting WAV exports the audio uncompressed at its original sample rate.
Is there a file size limit?
There is no server-side limit because processing is local. Practical limits depend on your device memory and browser — most modern devices handle files up to several gigabytes without issues.
