⚠️ This is a long file — decoded audio scales with length rather than file size, so very long files (over ~30 minutes) may be slow or use a lot of memory on this device.

Trimming isn't the same operation as compressing

Cutting out an unwanted section of audio is fundamentally different from shrinking a file's size — trimming just discards the samples outside your selected range and keeps everything else exactly as it was, sample for sample. There's no re-encoding of the audio you keep, no quality tradeoff to weigh, and nothing lossy about the process itself. This is part of why the result exports as WAV: since nothing about the kept audio changed, there's no reason to run it through a lossy encoder that would introduce the very quality loss trimming itself never causes.

Frequently asked questions

Is this audio trimmer really free?

Yes, completely free with no sign-up and no limit on how many files you trim.

What format do trimmed files download as?

WAV — an uncompressed, lossless format supported everywhere. Files are larger than MP3, but there's no quality loss from re-encoding.

Does my audio get uploaded anywhere?

No. Trimming happens entirely in your browser — your file is never sent to a server.

Is there a file size or length limit?

No hard limit, but very long files (over ~20 minutes) may be slow to process depending on your device.

Can I trim from the middle of a file, not just the ends?

This tool keeps one continuous selected range and trims everything outside it. To remove a section from the middle while keeping both sides, you'd need to trim and export twice, then join the two pieces back together.
