Questions about Trim Audio
Why does the output WAV sound identical but bigger?
WAV is uncompressed. Run the exported file through Compress Image's sibling tools, or encode to MP3 with your usual player.
Does it support trimming mid-song precisely?
Resolution is one sample, so type the timestamp or nudge by 0.05 s for a clean edit.
About Trim Audio
Cut and trim audio clips to the exact length with our free online Trim Audio. 100% browser-based, fast, and private—no login or file uploads required.
These audio tools edit sound without a desktop editor: trim and join clips, convert formats, record from microphone, and adjust volume, speed, pitch or equalisation while you listen to the result.
This tool runs in your browser. The file is not uploaded. Work on a copy and preview before downloading: trimming and speed changes are destructive to the loaded clip, and re-encoding a lossy file twice adds audible artefacts.
