Frequently Asked Questions
What audio formats can I trim with this tool?
The trimmer supports all common audio formats including MP3, WAV, OGG, FLAC, M4A, and AAC. It uses the Web Audio API, so any format your browser can decode will work for trimming.
Why is the trimmed output saved as a WAV file?
WAV is a lossless format that preserves audio quality perfectly without any re-encoding artifacts. If you need a smaller file in MP3 or another compressed format, use our Audio Converter tool on the trimmed WAV file.
How precise is the trimming selection?
You can set start and end points down to the millisecond using the waveform editor handles or by typing exact timestamps. The visual waveform display helps you identify silence, beats, and speech boundaries for accurate cuts.
Is there a maximum file size I can trim?
Since all processing happens in your browser, the limit depends on your device memory. Most modern devices handle files up to 100-200 MB without issues. For very large files, consider splitting them with desktop software first.
Does the audio trimmer upload my files to a server?
No, all trimming is performed entirely in your browser using the Web Audio API. Your audio files never leave your device, making it completely safe for private, confidential, or unreleased audio content.
