More free audio tools
Same quality bar. Still free. Still no upload.
Your files never leave your device
Free to use, with no account, no usage limit and no watermark, because the work runs on your device rather than on our servers.
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 an audio file
WAV, MP3, or M4A stay local.
2. Set in and out
Cut silence or isolate a line.
3. Download the trim
Use it under picture or as a VO bed.
Questions
Is the trim lossless?
No. The browser has already decoded the source, and the export is 16-bit PCM WAV. You are not copying the original compressed packets, so this is a re-encode, not a lossless cut of the bitstream. That is also why a trimmed MP3 becomes a larger WAV.
Why does the waveform look flat on quiet material?
The display downsamples to one min/max pair per pixel across the whole file, so it is an overview, not a zoomed editor. Quiet speech can look like a line even when the samples are there. The export still contains every sample in the selection.
Is there a length limit?
Files up to 80 MB and 20 minutes once decoded, because the whole file is expanded to uncompressed audio in memory. Video files are accepted too, and only their sound is kept. The WAV keeps the source's sample rate and channels.

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.
