Trim WAV online: sample-precise cutting without installing anything
WAV (Waveform Audio File Format) stores audio in uncompressed PCM — each sample is an exact numeric value. This makes WAV ideal for professional editing: no compression artifacts, no lossy decoding, and sample-level cutting is absolutely precise. A WAV file can be trimmed and exported multiple times without any quality degradation.

Open full toolDifferences between trimming WAV and trimming MP3
- WAV is already in PCM, so there is no decoding step — the tool reads samples directly. MP3 must be decoded first (generating intermediate PCM data) before any trimming operation. The final result of WAV trimming is identical to the original in the selected segment — no risk of artifacts.

Frequently asked questions
Is the original WAV sample rate preserved in the exported file?
Yes. The tool operates on raw samples and exports the WAV with the same sample rate as the original file. If the original was 48 kHz, the export will also be 48 kHz.
Does this page replace official or professional review?
No. It helps explain the scenario and use the tool more safely, but real decisions should consider official sources, full context and qualified guidance when needed.
