Audio Tools That Don't Upload Your Files
Your audio is private. These tools process everything in your browser — nothing is sent to any server.
The Problem with Online Audio Tools
Most online audio editors upload your file to a server, process it remotely, and send the result back. This means: • Your audio passes through third-party servers • You have no control over what happens to your data • Processing is slow (upload + process + download) • Large files take forever or fail • Your audio could be stored, analyzed, or leaked
How cut.audio Is Different
cut.audio processes everything locally in your browser using WebAssembly. Your audio file is: • Loaded into browser memory on YOUR device • Processed by a C++ engine compiled to WebAssembly • Encoded and decoded entirely client-side • Never sent to any server, ever There is no upload endpoint. There is no server-side processing. The tools literally cannot access your files because there's no mechanism to do so.
Why This Matters
Use cut.audio with confidence for: • Confidential recordings — meetings, interviews, legal depositions • Proprietary content — unreleased music, voice-overs, ad recordings • Personal audio — voice memos, private conversations, journal entries • Sensitive material — medical dictation, therapy recordings, HR content If your audio is too sensitive to upload, it's not too sensitive for cut.audio — because there's no upload.

Open your browser's developer tools (F12) and go to the Network tab. You'll see that no audio data is sent to any server. Only the initial page load involves network requests.
Once the page is loaded, the core tools work without an internet connection. The WebAssembly engine runs locally and doesn't need the network for processing.
