Trim video (cut the start and end)
Your screen recording has ten seconds of waffle at the start, or you forgot to stop it at the end — just cut it. ConvertMeow lets you set a start and end point and keep only the middle. It uses stream copy (no re-encode): it slices by time without recompressing the picture, so it's near-instant and loses no quality. The file is processed locally in your browser and never uploaded.

Stream copy doesn't re-encode — near-instant, no quality loss; the start snaps to the nearest keyframe.

Why use ConvertMeow's Trim video?
- No re-encode, no quality loss: it stream-copies at keyframes, slicing time without recompressing, so the cut clip is as sharp as the original.
- Practically instant: skipping the heaviest step (encoding) means even a few-hundred-MB video trims in seconds.
- The video stays local: trim a screen recording or private clip and send it without it ever hitting a server.
Frequently asked questions
Trimming uses stream copy — it doesn't re-encode the picture, it just copies the data for the chosen time range as-is, so it's near-instant. Compression has to re-encode every frame to a lower bitrate, which is far more work and therefore slower.
Stream copy cuts at the nearest keyframe, so the start can snap to a nearby keyframe and be off by a fraction of a second (the inherent trade-off for no re-encode — you get speed and zero quality loss). For frame-exact editing you need editing software that re-encodes.
