FAQ

Frequently asked questions

Are my files uploaded anywhere?

No. Every tool on this site runs entirely in your browser using the Web Audio API. Your files never leave your device — there are no servers receiving your audio, no accounts, and nothing to delete afterwards.

What is the maximum file size?

100 MB per file. The limit exists because your browser holds the decoded audio in memory; larger files can make tabs sluggish or crash on low-memory devices.

Which audio formats are supported?

You can upload MP3, WAV, FLAC and OGG files. Processed results can be downloaded as WAV (16-bit, 24-bit or 32-bit float — all lossless) or MP3 at 128, 192 or 320 kbps.

Is it really free?

Yes — every tool is free, with no sign-up, no watermarks and no usage caps. Everything happens on your own device, so there is nothing to pay for.

Will processing reduce my audio quality?

Effects are applied to the full decoded audio in your browser. Exporting as WAV 16-bit is lossless; exporting as MP3 re-encodes at the bitrate you choose, so pick 320 kbps for the closest match to the original.

Does it work on mobile?

Yes, in any modern mobile browser (Chrome, Safari, Firefox, Edge). Larger files and long renders are more comfortable on a desktop, but all 45 tools work on phones and tablets.
