Trim a video without re-encoding (keep original quality)
Most trimmers re-encode the whole file, which takes minutes and softens the picture. If a one-second tolerance is fine, you can cut at keyframes instantly and keep every pixel.
Quick answer. Open Trim Video, drop the file, drag the start and end handles (or type the times), choose "Fast · no re-encode" and press Trim. The cut snaps to the nearest keyframe, usually within one or two seconds, and completes in seconds at full original quality. Choose "Frame-exact" when the cut must land on a precise frame. Everything runs on your device.

Step by step
- Open Trim Video and add the clip.
- Set Start and End with the handles, the time boxes, or the "= playhead" buttons while previewing.
- Pick Fast (instant, keyframe-snapped) or Frame-exact (re-encodes just this clip).
- Press Trim and download. Use "Cut selection out" to remove a middle section instead.
Tips that save a second attempt
- Preview selection plays only the kept part so you can check the cut before exporting.
- Remove audio while trimming if you will add music later.
- Trimming before compressing or resizing saves time in every later step.
Frequently asked questions
Why is my Fast trim a second longer than I set?
Fast mode cuts at keyframes, which cameras place every one or two seconds. Use Frame-exact for a precise cut.
Does Frame-exact lose quality?
It re-encodes at a high setting; for social and brochure use the difference is not visible.
Is the video uploaded?
No. Trimming runs in your browser on your own device.
