Step 1: Select Your Video File

Click Apply. FFmpeg.wasm processes the crop operation entirely within your browser — no server involved.

Step 4: Download the Cropped Video

Download your newly cropped video immediately to your device in the original format.

Instagram Reels and TikTok (9:16)

Crop a landscape video to a 9:16 portrait ratio for vertical short-form content without re-shooting.

Instagram Feed (1:1)

Square crops work best for Instagram grid posts — crop once and it fits perfectly without letterboxing.

Zoom In on a Subject

Crop out a distraction at the edge of the frame or zoom into a specific area to improve the visual composition of a clip.

Your video never leaves your device. No upload, no server, no data collection at any stage.

FFmpeg.wasm runs on your own CPU — no waiting for uploads or server queues.

Once the page loads, cropping works without any internet connection.
