The Resize tool cropping a mountain clip to 9:16 at 720p, beside a phone with the ClipSizer editor

Free in your browser

Quick fixes, no install

ClipSizer's free browser tools, made by Metal Devs, resize a clip for any app, shrink it to fit a size limit or turn it into a GIF. Your video stays on your device, and each tool gets its own page.

A person by the mountains, reframed from a 16:9 clip into a 9:16 phone video at 720p

Make it the right shape

Turn any clip into 9:16, 1:1, 4:5 or 16:9. Choose Fit, Fill or Blur for the edges, depending on what you want to keep. Export at 720p with no watermark, and nothing is uploaded. Not sure of the size? See the platform specs.

Shrink it to a target size

Pick the size you need and ClipSizer squeezes the video to match, such as 20 MB for Discord or 25 MB for email. You get a file of up to 720p with no watermark, and your video stays on your device. Check the Discord limits first.

Compress a video
A skater clip turned into a looping strip of GIF frames at 15 fps

Turn a moment into a GIF

Trim up to 15 seconds of any video and save it as a GIF at 10 or 15 frames per second. There is no watermark, no sign-up, and nothing is uploaded, so a private clip stays private.
