Privacy
Audio Trimmer runs entirely in your browser on FileToolsHub. Your audio is processed in this tab and is never uploaded to our servers.
That means passwords, tokens, personal notes, and documents you paste or load stay on your device. Clear the page or close the tab when you are finished on a shared computer.
You still need a network connection to load the page the first time. After that, the core processing for Audio Trimmer does not require sending your content to FileToolsHub.
