About Audio Trimmer

Need to cut a section from an audio file? Whether you are creating a custom ringtone, extracting a sound effect, clipping a favorite part of a song, isolating a quote from an interview, or trimming silence from the beginning and end of a recording, this tool handles it with precision. Upload your MP3, WAV, OGG, M4A, or FLAC file and use the waveform display to visually set the start and end times for your clip. Fine-tune the selection by typing exact timestamps for frame-accurate trimming. Choose to export the trimmed clip as MP3 (smaller file size, great for sharing) or WAV (lossless quality, ideal for further editing). The tool decodes your audio using the Web Audio API, slices the AudioBuffer to the specified time range, and re-encodes it cleanly without any glitches or artifacts at the cut points. Everything runs in your browser — no files are uploaded to any server, keeping your audio completely private. This makes it safe for trimming confidential interviews, personal recordings, and licensed audio content.
