Frequently asked questions
- Is my video uploaded anywhere?
- No — trimming happens entirely in your browser using the WebCodecs API. The video never leaves your device.
- Does trimming re-encode the whole video?
- Where possible, the trimmed portion is copied directly without re-encoding, which is faster and keeps the original quality exactly. Whether that's possible depends on the video and the output format you choose.
- Can I change the output format while trimming?
- Yes — pick MP4, WebM, MOV, or MKV. It defaults to matching your video's original format.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online video trimmers |
|---|---|---|
| Video ever leaves your device | No — 100% client-side | Yes — uploaded to a server to process |
| Account required | Never | Often, past a certain usage level |
