The tool below locks the crop frame to a 1:1 ratio when you pick a square preset like 1080×1080 or 512×512. Drag the image inside the frame, pinch to zoom, and the export is always perfectly square.
For social avatars, 512×512 px is plenty. For Instagram feed posts, use 1080×1080. For high-resolution product thumbnails on Etsy or Amazon, go up to 2000×2000.
When you need a square crop
- Profile photos on every major social platform.
- Most marketplace and e-commerce thumbnails.
- Album covers and podcast cover art (1:1 standard).
- App icons (1024×1024 source).
- Some passport / visa photos (US 2×2, India 50×50 mm).
Composition for a square
Squares feel balanced when the subject is centered or placed on the intersections of an imaginary 3×3 grid (rule of thirds). Avoid putting the subject's face right at the top edge — most circular avatar masks clip the corners, and a face that's too high gets cut off the chin.
The algorithmic part
Squaring a 4:3 phone photo means cutting either the top & bottom (landscape orientation) or the sides (portrait orientation). The editor on this page locks the crop frame to 1:1 and lets you drag and zoom inside it — the result is exactly square pixels, not "almost square" with one row off.
Pick a target size while you're at it
Common square sizes: 400×400 (LinkedIn), 600×600 (US passport), 1080×1080 (Instagram square), 1024×1024 (AI inputs and app icons). See the 1080×1080, 600×600 and 1024×1024 pages for one-click presets.
Privacy
Every step happens inside the browser tab you have open. Your image is decoded, cropped and re-encoded by the same JavaScript engine that runs this page — there is no upload, no temporary file on a server, and no "processed copy" cached by us afterwards. When you close the tab, the blob is gone. We document the full pipeline on our Methodology and How it works pages.
