Is it safe to cut audio online?
Absolutely. Unlike traditional online tools that upload your private recordings or music to their servers, our Audio Trimmer uses the Web Audio API. Your files never leave your computer. All decoding and encoding happen entirely in your browser's memory, ensuring 100% privacy.
