About Audio Converter
Audio Converter changes an audio file from one format to another — MP3, WAV, M4A, OGG or FLAC — directly in your browser. Drop in a file, choose the output format, set the MP3 bitrate if you're making an MP3, and download the converted track in seconds. It reads the formats people actually have — MP3, WAV, M4A, AAC, OGG, FLAC and Opus — so it works as a general audio file, format, type or extension converter no matter what you started with.
Because it also accepts video, it doubles as an MP4-to-MP3 converter: hand it an MP4 (or another video file) and it pulls the audio out and saves it as MP3 or any other supported format. That covers the most common job — grabbing the sound from a clip — as well as everyday music conversion, like turning a WAV or M4A song into a smaller MP3, or a FLAC into something a phone or car stereo will play.
Everything happens on your own device using an in-browser build of ffmpeg, so your file is never uploaded to a server and nothing is stored. It's free, with no sign-up, no watermark and no file-size limits.
Frequently asked questions
- How do I convert MP4 to MP3?
- Drop your MP4 file in, set the output format to MP3, pick a bitrate, and click Convert. The tool pulls the audio track out of the video and saves it as an MP3 you can download.
- Can I extract the audio from a video without keeping the video?
- Yes. Feed it any supported video file and it discards the picture, keeping only the sound. You get back an audio file in the format you chose — MP3, WAV, M4A, OGG or FLAC.
- Which formats can I convert between?
- It reads common formats like MP3, WAV, M4A, AAC, OGG, FLAC and Opus, and can output MP3, WAV, M4A, OGG or FLAC. You can also drop in a video file to pull out and convert its audio.
- How do I convert WAV or M4A to MP3?
- Choose your file, set the output to MP3, pick a bitrate, and click Convert — the same steps work for M4A, AAC, OGG, FLAC or any supported source into MP3.
- Can I convert music and songs between formats?
- Yes. It handles music files as easily as any other audio — shrink a lossless WAV or FLAC song down to a portable MP3, or move an M4A track into OGG or WAV, whatever your player needs.
- How do I change an audio file's type or extension?
- Pick the file and select the format you want it saved as; the tool re-encodes it and hands back a new file with the matching extension. It's a proper conversion, not just a renamed extension.
- What's the difference between MP3, WAV, M4A, OGG and FLAC?
- MP3, M4A and OGG are compressed formats that keep files small for everyday listening. WAV and FLAC are lossless — larger files that preserve full quality, with FLAC compressed and WAV uncompressed. Pick MP3 for portability or FLAC/WAV for archiving.
- What MP3 bitrate should I pick?
- 128 kbps is fine for speech and casual listening, 192 kbps is a great all-round choice, and 320 kbps is the highest quality (and the largest file).
- Will converting improve the quality?
- No. Converting to WAV or FLAC is lossless from the source, but it can't recover detail that a compressed file like an MP3 already discarded. Converting one lossy format to another re-compresses and loses a little more.
- Is the audio converter free?
- Yes — completely free with no sign-up, no watermark, and no limits.
- Is my file uploaded to a server?
- No. The conversion happens entirely in your browser, so your audio never leaves your device.
- Does it work on mobile?
- Yes — it works in any modern browser on phones, tablets and computers.
