Click to upload a video file
Cropping a video changes its frame to a specific width and height — useful for converting landscape footage into vertical format for Shorts and Reels, or removing unwanted edges. This runs entirely in your browser using ffmpeg.wasm.
Step 1 — Upload your video.
Step 2 — Set the crop width, height and offset (offset is measured from the top-left corner of the original frame).
Step 3 — Crop and download the result.
Setting a crop area larger than the source video. Make sure width + offset X and height + offset Y stay within the original video's dimensions.
Using odd pixel dimensions. Most video codecs require even width and height — stick to even numbers to avoid encoding errors.
Check the file properties on your device, or use the Video Resolution Calculator once you know the pixel dimensions.
Yes — pick width and height values that match the ratio, for example 720x1280 or 1080x1920 for 9:16.
