Crop and pad a video to the exact aspect ratio each platform wants — 9:16 Reels/Shorts, 1:1 feed, or 4:5 portrait.. Social Media Video Cropper is a free online tool from the ToolsRift Video Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Load your video, choose the target platform ratio, decide between crop-to-fill or pad-to-fit, and export the correctly framed clip.
All three platforms are built around 9:16 vertical video, so that preset covers Instagram Reels, YouTube Shorts and TikTok in one export.
You can either crop in to fill the vertical frame (losing the edges) or pad with blurred or solid bars to keep the whole frame visible — both options are offered.
Yes, 4:5 is the taller-than-square portrait ratio Instagram and Facebook use for feed posts, while 9:16 is the full-height ratio used for Stories and Reels.
