What is AudioCutter Online?

AudioCutter Online is a free, browser-based audio editor for cutting, trimming, splitting, merging, and converting audio files. All processing happens locally in the browser, so audio files are never uploaded to a server — your data stays on your device.

It supports importing and exporting MP3, WAV, FLAC, OGG, AAC, M4A, AIFF, and MP4, and can extract audio from video files. Beyond basic cutting, it includes fade-in/fade-out, volume adjustment, normalization, dynamic-range compression, frequency filters (high-pass, low-pass, band-pass, notch), silence detection, and sample-level editing on a multi-fragment timeline with undo/redo, snap, zoom, and hotkeys.

Editing sessions can be saved as a project file (a ZIP archive that bundles the original audio with all cuts, fades, volume, and effects) and reopened later to continue work.

There are no sign-ups, no watermarks, no premium tier, and no hidden file-size limit — the practical limit is your device's available memory. It also exposes an integration API: the editor can be embedded as a popup from another site.
