About Video Resizer
Video Resizer re-encodes your video at a new size as an MP4. The 1080p to 360p presets set the short side, keep the shape of the picture and are greyed out when they'd be larger than your original. Square 1:1 and Vertical 9:16 make clips ready for social feeds. Your video is processed in your browser and is never uploaded.
FAQs
Why are some sizes greyed out?
Making a video larger than its original resolution doesn't add detail, so those presets are turned off.
Contain or Cover?
Contain shows the whole picture with black bars. Cover fills the frame and trims the edges.
How long does it take?
Toolsaku uses your device's hardware encoder, so it's usually faster than real time.
