Crop MP4 files

Upload an MP4 file, drag the rectangle over the area you want to keep, and crop. Cropping re-encodes the video, so longer files take a while.

Pixel-accurate MP4 cropping

Draw the region to keep on your MP4 and export it as a new file. The crop is re-encoded at high quality with the output sized exactly to your selection, and the work never leaves your machine.

Frequently asked questions

Can I crop a horizontal video to vertical?

Yes, select a tall region and the output becomes a vertical video, ready for stories and shorts.

Why is there re-encoding involved?

Changing the frame geometry requires producing new frames; codecs cannot crop in place. The encoder targets high quality to keep the cost invisible.

Are files uploaded?

No, the crop happens locally.
