Resize a video online: change its size and resolution
Resizing a video means changing its dimensions: taking a 4K video down to 1080p, lowering the resolution to lighten the file, or fitting the picture to a specific platform. Klipa resizes your videos online, for free.
Why resize a video?
A video shot in 4K is heavy and adds nothing on a phone screen. Resizing it to 1080p or 720p cuts its weight with no visible loss. Conversely, some platforms demand a precise size: resizing the video keeps them from cropping or stretching it for you.
Resize without stretching the picture
Resizing is not stretching: the aspect ratio is preserved, the picture is neither squashed nor pulled. You pick the target resolution and the video is resized cleanly.
Resize or reframe: what is the difference?
Resizing changes the size of the whole picture. Reframing changes the frame — that is what you need to go from a horizontal video to a vertical one, with our AI reframing tool.
