Uses ffmpeg.wasm: about 30 MB is downloaded the first time, then cached. Processing speed depends on your device — a 1-minute 1080p clip takes roughly 1–3 minutes.
● Your video is processed locally in your browser and never uploaded. Large files need a recent computer with enough memory.
How it works
Drag the frame to move it and its corner to resize it; a ratio preset keeps the proportions. The crop is applied with ffmpeg's crop filter in the video's real resolution and re-encoded to H.264 MP4, with the audio kept. Crop dimensions are rounded to even numbers.
