How to Use

  1. Upload the image you want to crop (JPG, PNG, WebP, or iPhone HEIC β€” up to 50MB per file)
  2. Pick an aspect ratio for the destination: Instagram square 1:1, Stories and Reels 9:16, portrait 4:5, YouTube/TikTok covers 16:9, or "Free" for custom dimensions
  3. Drag the crop frame to adjust position and size; use zoom and rotation controls to straighten or re-center
  4. Click "Crop image" β€” everything runs locally in your browser and the file never reaches a server
  5. Download as JPG (photos), PNG (transparent logos), or WebP (web-optimized for Core Web Vitals)
  6. For ID photos (Korean passport 35Γ—45 mm, US passport 2Γ—2 inch, EU schengen 35Γ—45 mm) use free crop and set the exact millimeter dimensions

All processing is done in your browser, and files are never sent to a server.
