Trim and crop videos in your browser
Cut a clip by start and end time, and optionally crop the frame to a rectangle — for example to remove black bars or make a square video for social media. Processing uses FFmpeg (WebAssembly) locally; nothing is uploaded.
What is fast mode?
Fast mode copies the streams without re-encoding, which is nearly instant and lossless, but the cut snaps to the nearest keyframe. Turn it off for frame-accurate cuts. Cropping always re-encodes.
