How this audio converter works
Add a file
Drop an audio or video file (up to 500MB) into the audio converter. We validate the extension before loading — MP3, WAV, FLAC, AAC, OGG, M4A, Opus, MP4, MOV, and WebM are supported.
Choose format & options
Pick an output format in the audio converter, open advanced settings if you need sample rate, channels, or bitrate, and for MP4/WebM choose black or a custom cover.
Convert & download
Click Convert and wait for the local progress bar. Then download your converted file or start another audio converter job.
Audio Conversion Features
Nothing leaves your browser
The audio converter processes files in your tab using WebCodecs. We do not receive your audio or video — ideal for unreleased tracks, client dailies, and private voice recordings.
Broad format support
Import MP3, WAV, AAC, FLAC, OGG, M4A, M4R, WMA, Opus, AIFF, AMR, MP4, MOV, or WebM. Export popular audio formats or a still-image MP4 / WebM for social workflows — one audio converter covers both audio-only and audio-to-video exports.
Fine-grained control
Optional sample rate, mono/stereo, and bitrate for lossy codecs — ideal for podcasts, voiceovers, and smaller files when you convert audio with this browser tool.
Audio to video
Export a 1280×720 clip with a black background or your own JPEG/PNG/WebP cover — handy when a platform expects video files instead of plain audio.
