Will WAV sound better than the MP3?

No – converting cannot restore what MP3 compression removed. WAV is useful because editing software handles it best and repeated edits do not add further loss.

Limitations

Up to 60 minutes and 500 MB per file.
Which input formats open depends on your browser: Chrome and Edge read the most formats.

Privacy

Files you choose are read into your browser’s memory and processed on your device; they are not uploaded to a server. Temporary download links are released after use, and the offline cache never stores your documents. More about privacy and limits.

Frequently asked questions

Why is the WAV file so much bigger?

WAV stores audio uncompressed – about 10 MB per minute in stereo.

Are my files uploaded?

No. The audio is decoded and processed in your browser, so recordings and videos never leave your device.

Is it free?

Yes – free with no signup, no watermark and no daily limit.

How long can a recording be?

Up to 60 minutes per file (and 500 MB). The whole recording is held in your device’s memory while it is processed, so very long files need a computer rather than an older phone.
