Convert to FLAC
Files never leave your device.
About FLAC
FLAC is lossless compression: it sounds identical to WAV at roughly half the size. Convert to FLAC to keep audio lossless at about half the size of WAV. Drop in any audio or video file — the audio is converted in your browser, and nothing is uploaded.
Questions
Are my files uploaded?
No. The conversion runs in your browser, on your device. Your files are never sent to a server, and closing the tab discards everything.
Will FLAC sound better than the original?
No — FLAC is lossless, so it keeps exactly what the source contains, but it can’t restore detail a lossy source (like MP3) already lost.
Is there a file size limit?
There’s no set limit. Files are converted on your device, so very large ones depend on its free memory and storage — an hour-long recording converts fine on a recent phone.
Can I convert several files at once?
Yes. Add as many files as you like; they convert one after another to FLAC, and you can download each one or all of them together.
Which browsers does it work in?
Current Chrome, Edge, Firefox and Safari on desktop, and Chrome and Safari on phones. Firefox on Android can only convert WAV files. If a file can’t be converted in your browser, its row says so.
