Why convert to MP3?
MP3 is the one audio format every device understands: phones, laptops, car stereos, smart speakers, old MP3 players and every app. If a song, voice memo or recording will not play somewhere, MP3 almost always fixes it.
Already have an MP3?
Drop an MP3 and the converter suggests WAV, M4A and other formats. To shrink or re-encode an MP3 instead, use Change MP3 Bitrate or the MP3 Compressor.
Good to know
Video is encoded with H.264 (x264) and AAC unless the format needs something else, and audio uses each format's standard encoder (LAME for MP3, native AAC, Vorbis, Opus, FLAC). When the codecs already match, streams are copied instead of re-encoded.
Supported files
Any common audio or video file: MP4, MOV, MKV, WEBM, AVI and other video formats, and MP3, WAV, M4A, FLAC, OGG, OPUS, WMA and other audio formats. Files up to 1 GB each.
Frequently asked questions
What bitrate should I choose?
320 kbps for music you care about, 192 kbps for everyday music, 128 kbps for podcasts and 64–96 kbps for voice recordings.
Can I convert a YouTube link?
No. This site only converts files that are already on your device. Downloading videos from YouTube is against its terms of service.
Do I have to pay or sign up to use the MP3 Converter?
No. There is no account, no payment and no watermark. The only limit is 1 GB per file, set by what browsers can handle.
Do you keep a copy of my files?
We never receive them. All processing happens on your device, so there is nothing for us to store or delete.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
