More free audio tools
Same quality bar. Still free. Still no upload.
Your files never leave your device
This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.
- Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
- Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
- You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
- Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.
A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.
This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.
How it works
1. Drop audio or video
Interview, podcast, or VO. Video is accepted for its audio track.
2. Tune threshold and minimum
Same RMS silence detection as the finder. Red bands are what will be cut.
3. Download the cut WAV
Keep regions are concatenated into 16-bit PCM WAV. CSV cut list is optional.
Questions
How is this different from the Audio Silence Finder?
The finder only builds a CSV cut list of silence and keep timestamps. This cutter uses the same RMS detection, then concatenates the keep regions and downloads a WAV with the silences removed. Use the finder when you will cut in an NLE; use this when you want the trimmed file now.
Will joins click or pop?
Exports are 16-bit PCM WAV spliced at sample boundaries. Most speech cuts are clean. Hard consonants at a join can still click the way any hard edit can. Loosen the threshold or raise the minimum silence if you are cutting mid-breath.
Does this remove silence from video picture too?
No. Video files are decoded for their audio track only. Re-timing picture to match a silence-cut soundtrack needs an editor or a heavier in-browser remux, which this free tool does not do. Export the WAV and cut picture to match, or use the CSV cut list.
Why WAV and not MP3?
Browsers decode many codecs but ship no MP3 or AAC encoder. WAV is uncompressed PCM we can write from the keep samples, same as the free audio trimmer and denoise tools.
Do my files get uploaded anywhere?
No. This free tool runs entirely in your browser using the Canvas and File APIs. The file you choose is read into memory on your own machine, processed there, and offered back as a download. Nothing is sent to a server, which is also why it keeps working with your network off.
Is it actually free, or is there a catch?
Actually free, with no account and no limit, because it costs nothing to run. The work happens on your device rather than on our hardware. That is different from generating with an AI model on Versely, which does cost credits. There is no free tier for generation.

These rearrange files. Versely makes new ones.
Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist (video from a prompt, a voice, a score) runs a model, and that costs credits.
