What audio quality can I expect from the MP3 output?

Quality depends on the audio stream in the original video. Choosing 320 kbps gives you the closest result to the source. For most speech and general content, 192 kbps is more than sufficient.

Do all MP4 files contain audio?

No. Some MP4 files are video-only. If your file has no audio track, the tool will notify you. Files with audio will convert without issues.

Yes, completely free with no registration or payment required.

What devices can play the output MP3?

MP3 plays on smartphones, computers, car stereos, portable players, smart speakers, and virtually every other audio-capable device.

Will the MP3 be the same length as the video?

Yes. Unless you specify a time range, the audio output matches the full duration of the video.

How long does my file stay on the server?

Files are automatically and permanently deleted within one hour of processing.

Can I convert a one-hour video to MP3?

Yes, longer videos are supported within the 500 MB file size limit. Very high-quality long recordings may exceed that limit, in which case trimming the video beforehand is recommended.
