Audio converter

One page for every conversion: drop an audio file or a video, choose MP3, WAV or AIFF, set the sample rate, channels and quality, and download the result. The conversion runs inside your browser, so the file is never uploaded and there is no queue.

This page needs JavaScript for the tool itself. Open it in a browser to use it.

What goes in and what comes out

In: MP3, WAV, AIFF, FLAC, OGG (Vorbis and Opus), M4A and AAC, and the audio track of MP4, MOV and WebM video, which is everything the browser itself can play. Out: MP3 at 64 to 320 kbps, WAV at 16-bit, 24-bit or 32-bit float, or AIFF at 16-bit or 24-bit.

Every setting explained

Sample rate defaults to the source; 44100 Hz is the CD and streaming standard, 48000 Hz is used for video, and WAV or AIFF can go up to 96000 Hz (MP3 stops at 48000 Hz). Channels: keep the source, force stereo, or mix down to mono for speech. Bitrate sets MP3 size and quality: 128 kbps for speech, 192 kbps for everyday music, 320 kbps for the best MP3 can do. Bit depth applies to WAV and AIFF: 16 for CDs and general use, 24 for a session, 32-bit float for editors that work in floating point.

Why it runs in the browser

Your file is read on your device, converted there, and saved from there. Nothing is sent to BeatRootRaga, which is why there is no upload wait, no size limit beyond your device's memory, and no account. Close the tab and nothing remains anywhere.

What it does not do yet

It writes MP3, WAV and AIFF only; FLAC, OGG and AAC output need an encoder the browser does not have built in. Tags, artwork and chapters are not copied to the new file. One file at a time.

Dedicated pages

The common conversions have their own page with advice for that case: MP4 to MP3 for video, MP3 to WAV for editing, WAV to MP3 for sharing, M4A to MP3 for voice memos. All of them use this same converter.

Questions people ask

Is the audio converter free, and is my file uploaded?

Free, no account, no watermark, and nothing is uploaded. Decoding and encoding both happen inside your browser.

Can it output FLAC or OGG?

Not yet. Output is MP3, WAV or AIFF. FLAC and OGG files can be read and converted to any of those three.

Is there a file size limit?

No fixed limit. The whole track is decoded into memory before encoding, so a phone handles a typical song or episode and a laptop handles hours of audio.

Does it keep the tags and artwork?

No. The new file carries the audio only. Add tags in your player or a tag editor afterwards.

Why did a file fail to convert?

The browser could not decode it. Video with no audio track, Apple Lossless in Chrome or Firefox, copy-protected purchases, and a few rare codecs are the usual reasons. Try another browser or export the audio from the source app first.

Which settings should I use for a podcast?

MP3, mono, 96 or 128 kbps at 44100 Hz. That is what most podcast hosts recommend and it keeps the file small.
