Shorts Resize & Safe Zoneについて
Reframe a YouTube video for Shorts, TikTok or Reels without guessing what will be cut off. Choose 9:16, 1:1 or 4:5, fill the sides with a blurred background or drag a crop, and preview generic safe-zone guides (no brand logos). Export 1080×1920 or 720×1280 at 30 fps, H.264 when your browser supports it, with a warning if the clip is over 60 seconds. Optional smaller-file compressor. Everything stays on your device.
