Extract audio as mp3 from a video on your phone
한국어Pick the file from your gallery and press extract audio. No app to install, and the file never leaves this screen.
What works well on a phone
Extracting audio does not re-encode video, so it is fast even on a phone. Good for a meeting recording or a lecture where only the sound matters.
Trim and change container also skip re-encoding and run fine on a phone.
Subtitle conversion (smi, srt, vtt) works on text only, with no engine, so it is the lightest task on a phone.
What is risky on a phone
Shrinking and making a GIF re-encode every frame, which uses a lot of memory. A long or large video can stop midway on a phone.
In that case the screen tells you first, and for a genuinely large file, using a PC works better.
Pick the file right here in the browser; there is no separate app to install.
