Will cutting MP3 reduce audio quality?

No! The selected audio range is extracted losslessly without degrading sound clarity.

Do I need to install software or sign up to cut MP3 files?

No. The MP3 cutter tool runs entirely in your browser with no download, no plugin, and no account. There is no watermark on the output and no daily usage limit.

Are my MP3 files uploaded to a server?

No. Your file is read into browser memory, processed on your own device, and released when you close the tab. Nothing is transmitted, stored, or logged at any stage.

Is there a file size limit?

There is no server-imposed cap because the work happens locally. The practical ceiling is your device memory, so desktops handle large MP3 files comfortably while older phones may struggle with very big ones.

Which browsers and devices does this MP3 tool support?

Every current version of Chrome, Edge, Firefox, Safari, Brave, and Opera on Windows, macOS, Linux, Android, and iOS. No browser flags or extensions are required.
