audio converter
Convert MP3, WAV, FLAC, M4A and OGG, or turn video into MP3, free with no upload.
convert audio without uploading it
Turn mp3 into wav, wav into ogg, flac into mp3, or any other direction between mp3, wav, flac, m4a and ogg. It also works as a video to mp3 converter: drop an mp4, mov or webm and the audio track comes out in whatever format you pick. Choose the bit depth, bitrate, sample rate and channels, or use a preset like wav 24-bit for sampling.
Decoding and encoding happen in your browser, so conversion works offline, there is no file size limit and your audio never leaves your device. Single files download directly and batches arrive as one zip.
common questions
does converting mp3 to wav improve quality?
No. Converting to wav stops any further quality loss but cannot restore what the mp3 encoding already removed. Convert to wav when a sampler or editor needs it, not to upgrade the sound.
which format should I pick?
wav 24-bit for sampling and editing, mp3 320 for sharing and phones, ogg when you need small files that still sound good. The presets cover the common cases.
how do multiple files download?
A single file downloads directly. Batches are bundled into one zip, because browsers block a page from firing many downloads at once.
can I turn a video into mp3?
Yes. Drop an mp4, mov or webm in with everything else and the audio track is pulled out and converted like any other file. Handy for sampling from phone videos and screen recordings.
is there a file size limit?
No hard limit, since everything runs on your device. Very long files are bounded only by your browser's memory.
