Common uses
- Turn a landscape video into a vertical 9:16 clip for Reels, Shorts or TikTok.
- Make square 1:1 videos for feeds.
- Remove black bars, a watermark area at the edge or an unwanted part of the frame.
Using the crop box
- Drag inside the box to move it; drag the handles to resize.
- Pick a ratio to lock the shape, or “Free” for any size.
- Type an exact width and height in pixels if needed; sizes are rounded to even numbers, as video encoders require.
Result
The video is re-encoded to H.264 MP4 at high quality and the original sound is kept. Cropping removes pixels, so a small cropped area gives a smaller picture.
Frequently asked questions
Is the sound kept?
Yes, the audio is kept unchanged in length.
Are my videos uploaded?
No. The video is cropped on your device.
Can I crop to 9:16 for TikTok?
Yes. Choose 9:16 and move the box over the part you want to keep.
Why does the size change to even numbers?
H.264 video needs even width and height; the box is rounded by one pixel at most.
Which formats work?
