Resize & Crop Video

Resize or crop a video's framing with presets (original, 16:9, 9:16, 1:1, 4:5, 4:3) or custom dimensions, with contain, cover, or crop fitting, and framing position. It never distorts the content or forces width and height while ignoring the original ratio — fitting always scales uniformly.

Frequently asked questions

Does it distort the video when changing the aspect ratio?
No. Fitting always scales uniformly (containing, covering, or cropping the frame); it never stretches the content unevenly.
Can I convert a horizontal video to vertical for social media?
Yes, using the 9:16 preset with whichever fit you prefer (cropping the frame or adding a solid background around it).
