Is my audio uploaded?

No. The file is decoded and re-encoded in your browser. Nothing is transmitted and nothing is kept after you close the tab.

Which input formats work?

Anything your browser can decode, which in practice means MP3, WAV, M4A, AAC, OGG, Opus, FLAC and the soundtrack of most MP4, MOV and WebM videos.

Which bitrate should I choose?

192 kbps is a good default for music and 128 kbps is plenty for speech. 320 kbps is the highest MP3 quality; 96 kbps gives the smallest file.

Why is my WAV file so big?

WAV stores every sample uncompressed — roughly 10 MB per minute in stereo. That is expected; choose MP3 when size matters.

Can I convert several files at once?

One at a time for now, which keeps memory use predictable on phones and older laptops.

Does converting reduce quality?

Going to WAV does not. Going to MP3 is lossy, and re-encoding an already compressed file loses a little more — start from the highest-quality source you have.

Audio Converter — Overview

About this tool

What is Audio Converter?

The Audio Converter turns audio files into MP3 or WAV inside your browser, and can also lift the soundtrack straight out of a video. Anything your browser can play — M4A, AAC, OGG, Opus, FLAC, WAV, MP3, or the audio in an MP4 or MOV — can go in.

MP3 is the format that plays literally everywhere, from car stereos to upload forms that reject anything else. WAV is uncompressed, which is what editors, transcription tools and podcast producers usually ask for. Being able to move between the two, with control over bitrate, sample rate and channels, covers almost every practical request.

Conversion is local: the file is decoded by the Web Audio API on your device and re-encoded there too. A confidential interview recording, a voice note or an unreleased track is never uploaded.

Use cases & scenarios

Where it fits

Getting MP3 for a stubborn upload form

Podcast hosts, contest entries and school portals often accept MP3 and nothing else.

Preparing audio for transcription

Mono at 16 kHz is what most speech engines prefer, and it makes the file far smaller.

Pulling the sound from a video

Turn a recorded talk, lecture or interview into an audio file you can listen to on the move.

Handing WAV to an editor

Convert a compressed source to uncompressed WAV when a tool refuses anything else.
