Frequently Asked Questions
Does the tool only accept MP4 files?
This page is optimised for MP4 input, but most common video formats (WebM, MKV, MOV, AVI) also work if you upload them.
How long does converting MP4 to MP3 take?
Most MP4 files convert in under 30 seconds. Processing time depends on video duration and server load.
Will the MP3 audio quality be good?
FFmpeg extracts the audio stream from the MP4 at high quality. If the source audio is already AAC, conversion to MP3 involves one re-encode, which is transparent at high bitrates.
Is my MP4 file kept private?
Yes. Files are processed privately and deleted automatically within 60 minutes. We never store, sell, or analyse your content.
Is this tool free to use?
Completely free — no watermarks, no subscription, no account required.
