Technical Guide
How Audio Trimming Works
Our audio trimmer uses browser-based processing with FFmpeg WebAssembly, allowing you to cut audio files without uploading them to any server.
Precision Trimming
The visual waveform display shows the amplitude of your audio over time. By dragging the start and end handles, you can select exactly which portion of the audio to keep.

When you trim audio, we preserve the original quality. The trimmed portion is extracted without re-encoding when possible, maintaining bit-perfect quality.

Frequently Asked Questions
Common questions about trimming audio.
Our trimmer allows millisecond-level precision. You can drag the handles on the waveform to select exact start and end points, and fine-tune using the time display.
Trimming itself does not reduce quality. When exporting, quality depends on your chosen format. For lossless quality, export as WAV or FLAC.
Currently, you can trim one continuous section at a time. For multiple sections, trim each section separately and use our Merge tool to combine them.
You can trim MP3, WAV, FLAC, OGG, M4A, and AAC files. Export to any of these formats after trimming.
There is no strict limit, but very long files (over 2 hours) may take longer to load and process. For best performance, we recommend files under 200MB.
