AudioTools Audio Trimmer lets you cut any audio file directly in your browser. Drop your MP3, WAV, FLAC, or OGG file, see the waveform, drag the trim handles to select the portion you want, and download the result. No upload to any server — all processing uses the Web Audio API.

How to Trim an Audio File

Drop or select your audio file. A visual waveform appears with green (start) and red (end) trim handles. Drag the handles or type exact timestamps to define your trim region. Click "Preview" to hear the selection, then "Cut & Download" to save as WAV.

Supported Formats

Input: MP3, WAV, FLAC, OGG, AAC, M4A, WebM — any format your browser can decode. Output is always WAV (uncompressed, lossless). Need a different format? Use our Audio Converter to convert the result.

Privacy

Your audio file never leaves your device. Trimming uses the Web Audio API's OfflineAudioContext to process audio entirely in your browser. There are no servers, no uploads, no data collection.
