Convert audio files between MP3, WAV, OGG, FLAC, AAC, M4A, and Opus formats.
About Convert Audio
Convert Audio transcodes a sound file between MP3, WAV, OGG, FLAC, AAC, M4A, and Opus. Reach for it when a tool or device demands a specific format, you need a lossless WAV from an MP3, or you want a smaller Opus file for the web. The conversion happens entirely in your browser, so your recordings never get uploaded to a server.

Frequently asked questions
Which audio formats can it read and write?
It accepts any audio file and converts among MP3, WAV, OGG, FLAC, AAC, M4A, and Opus.
Does converting between lossy formats lose quality?
Going from one lossy format to another (say MP3 to AAC) re-encodes and can lose a little quality. Converting to WAV or FLAC is lossless, but won't recover detail the source already discarded.
Does my audio get uploaded?
No. Decoding and re-encoding run in your browser using local processing, so the file stays on your device.
Is there a file-size limit?
There's no fixed cap, but very large files are limited by your device's available memory since everything is processed in-browser. Long recordings on a low-memory device may be slow.
Will it keep the original sample rate and channels?
It preserves the source audio's characteristics during transcoding unless the target format constrains them. The output matches the format you choose.
