📝 What is the YouTube Shorts Generator?
Do you have long horizontal videos that you want to post on Shorts or TikTok? Editing them manually takes hours. You have to crop, resize, and maybe even stack two clips (like gameplay + facecam).
This tool does it all in your browser. You upload a video, and it lets you Drag & Drop to select the perfect vertical crop.
But the best part? It has a Split Screen Mode. This is perfect for gaming or reaction videos. You can select the “Top” area (the game) and the “Bottom” area (your face), and the tool stacks them perfectly into a 9:16 vertical video.
It works instantly without uploading files to a server, so it is 100% private and fast.
