Complete Guide: Audio Trimmer
Everything you need to know about using this tool effectively
The Audio Trimmer lets you cut away unwanted sections from your audio files. Set the start and end points to keep only the portion you need. Works with MP3, WAV, OGG, FLAC and other formats. All processing happens in your browser.
This tool uses the Web Audio API to precisely trim audio files. You specify the start time and end time, and the tool extracts only that portion of the audio. The trimming is non-destructive. It creates a new file with only the selected section.

Does trimming reduce audio quality?
No. The trimming process creates a new file with only the selected portion at the original quality. No re-encoding quality loss occurs.
What audio formats are supported?
The tool supports MP3, WAV, OGG, FLAC, AAC, and most common audio formats. The exact support depends on your browser.
Can I trim multiple files at once?
Currently the tool processes one file at a time for precise control over each trim.
How do I find the exact time to trim?
Upload your file and use the preview player to find the exact start and end points. The time is displayed in seconds.
Can I trim from the beginning only or end only?
Yes. Set the start time to 0 to trim just the end, or set the end time to the full duration to trim just the beginning.
What happens to the rest of the audio?
Only the selected portion is saved. The rest is discarded. Make sure you have the correct section before downloading.
