Why audio editing belongs on your device
Private by design
Voice memos, interviews, unreleased tracks — audio is personal. Here it is decoded and edited in your own browser memory. There is no server that could see, store or leak it.
No queue, no waiting
Uploading a 50 MB track, waiting for a server, downloading it back — skipped entirely. Editing starts the moment you drop a file.
Free, really
Local processing costs almost nothing to run, so the tools are free without watermarks, signup walls or export limits.
Frequently asked questions
Is Free Audio Editor really free?
Yes — every tool on this site is free with no signup, no watermark and no daily export cap. Because all processing happens in your own browser, there are no server bills to recover.
How is my audio kept private?
Your files are never uploaded. Decoding, editing and exporting all run locally with the Web Audio API inside your browser tab. You can disconnect from the internet after the page loads and every tool keeps working.
Do I need to install anything?
No. The tools are web apps that run in any modern browser — Chrome, Edge, Firefox or Safari, on desktop and mobile.
Which audio formats are supported?
You can open MP3, WAV, M4A/AAC, OGG, FLAC and WebM audio, and save results as MP3 (128–320 kbps) or lossless WAV.
