What is Video Cropper?
Video Cropper allows you to crop the visual frame of your video clips. Re-frame widescreen 16:9 landscape footage into vertical 9:16 mobile formats (for TikTok, Instagram Reels, and YouTube Shorts) or square 1:1 posts with custom pan and zoom controls.
Unlike legacy online utilities that upload sensitive media and documents to remote cloud storage, Shadow Toolkit executes this entire operation directly within your browser's local runtime. Your raw data never crosses the network.
