What it does

Trim — scrub a filmstrip timeline, drag in/out handles, step frame by frame, or type exact times. A slim bar under the timeline slides the whole selection without changing its length.

Multi-clip — queue several cuts from one video and export them all at once into a folder you choose.

Crop — draggable box with ratio presets (16:9, 9:16, 1:1, 4:5, 2:3, 21:9, custom…).

Resize & frame rate — percentage presets or exact pixels; any fps.

Compression — one slider, smaller file ↔ bigger file, with a live size estimate.

Pictures — single-frame snapshot, animated GIF, and two kinds of contact sheet:

• Auto storyboard — N×N frames spread evenly across the selection
• Manual storyboard — pick the exact frames yourself, with thumbnails

Outputs

Files are named from the source, timestamp and settings, e.g. holiday_1m37s_1280x720_30fps.mp4.

Good to know

• Export runs in real time — a 30-second clip takes about 30 seconds. Keep the tab on screen; it pauses if you switch away and resumes when you return.
• It re-encodes, so output isn't bit-identical to the source. The compression slider controls that trade-off.
• GIF is 256 colours and grows quickly — smaller width and 10–15 fps work best.
• Manual storyboards hold up to 25 frames; grids go to 10 × 10.

Requirements

Chrome or Edge. Firefox mostly works but falls back to WebM. No server, no dependencies, no build step.
