Resize Video Online Free — FAQ
Will resizing distort my video?
The tool scales the video to fit your target size and pads with black bars if the aspect ratio does not match, so the original footage is never stretched or cropped unexpectedly.
Are my videos uploaded to a server?
No. Resizing runs locally in your browser using FFmpeg WebAssembly.
What size range is supported?
Width and height can be set anywhere from 64px up to 3840px (4K) on each side.
