Frequently Asked Questions
What file formats can I convert to MP3?
You can convert MP3, WAV, FLAC, M4A, AAC, OGG, Opus, WebM, MP4, MOV, and 3GP. Video files are supported too — only the audio track is extracted and converted. If your browser can play the file, this converter can turn it into an MP3.
Is the MP3 converter free?
Yes. Completely free. No sign-up, no watermark, no ads, no limits on how many files you can convert. Max file size is 200MB.
What bitrate is the output MP3?
Every converted MP3 is encoded at 192 kbps — a safe balance of quality and file size that plays cleanly on phones, car stereos, and every MP3 player made in the last 20 years.
Is my file uploaded to a server?
No. The converter runs entirely in your browser using the Web Audio API. Your file never leaves your device — nothing is uploaded or stored anywhere.
Does it convert MP4 or MOV video to MP3?
Yes. Drop an MP4, MOV, WebM, or 3GP file and the converter extracts the audio track and encodes it as MP3. Perfect for ripping audio out of screen recordings, interviews, lectures, and music videos.
Can it handle large files?
Files up to 200MB are supported. That covers most podcasts, full albums, and hour-long video recordings.
Will I lose quality when converting?
Converting from a lossless source like WAV or FLAC to MP3 involves expected lossy compression — at 192 kbps it is transparent for most listeners. Converting one lossy format to MP3 (M4A, OGG, or MP3 re-encoding) introduces a small additional loss, which is normal for any MP3 converter.
Does the converter work on mobile?
Yes. The converter works on Chrome, Firefox, Safari, and Edge on desktop and mobile. Drop a file from your phone and the MP3 downloads right there.
