Frequently Asked Questions
Everything you need to know about converting your MP4 to MP3.
Is it free, or is there a paid plan? expand_more
Completely free. No account, no signup, no watermark, and no paid tier. Unlike Clideo, which watermarks free exports and caps free uploads at 500MB, VidClean adds nothing and accepts files up to 2GB.
Will the audio quality be affected? expand_more
The output is MP3 at 192kbps. For spoken-word content (podcasts, interviews, voiceover, lectures) the difference from the source audio is inaudible to almost everyone. For music, 192kbps is broadly transparent and matches the bitrate most streaming services use for previews.
What video formats can I convert to MP3? expand_more
MP4, MOV, MKV, and WebM up to 2GB per file. The output is always MP3 at 192kbps regardless of input format.
How large a file can I convert? expand_more
Up to 2GB per file, with no cap on how many files you convert. There is no watermark on the output.
How long does conversion take? expand_more
Most files under 100MB finish in under 30 seconds. Files in the 100 to 500MB range usually take 30 to 60 seconds. Multi-gigabyte files can take a few minutes. There is no silence detection step, so this is significantly faster than tools that also process the audio.
Is my video file kept private? expand_more
Yes. Files are processed on a private server and automatically deleted 15 minutes after the job finishes. We never view, share, train on, or store your content.
