Audio Tools
Record, cut, merge, boost and convert audio tracks. 8 tools
Audio work is mostly small, repetitive editing: trimming dead air from the start of a recording, joining an intro to a main take, boosting a voice recorded too far from the microphone, or converting a format some device refuses to play.
The recordings involved are usually private — interviews, meetings, voice notes, unreleased music — and voice is treated as biometric data under several privacy frameworks. Every audio tool here decodes and re-encodes through the Web Audio API and WebAssembly codecs in your browser, so nothing is transmitted and there is no duration limit. You can also record directly in the page, with the audio written straight to your downloads when you stop.
All 8 audio tools, free and without an account
Every tool listed above runs entirely inside your browser. Nothing you open is uploaded, there is no sign-up, no file-size limit, and no watermark on anything you export. Pick a tool to get started, or use the search box at the top of the page to jump straight to one.
Each tool page includes a written guide explaining what the tool does, why it works the way it does, and the mistakes that most often catch people out. Longer walkthroughs live on the blog, and you can read more about who builds these and exactly what data we handle in the privacy policy.
