READY-TO-USE IMAGE TOOL

No upload. The image never leaves your device; nothing is saved by this site.
Put this frame to work
A 1200 × 627 wide image is about 1.91:1. Cropping a 1200 × 1200 square to it removes 573 pixels of height, so a headline at the bottom of the square may be lost.
Resizing preserves a source image's shape; cropping removes edges to fit a different one. Download the crop as PNG or JPEG above.
