Resize Image for Instagram Online
Runs 100% in your browser — your files never leave your device.
Instagram crops unpredictably when the aspect ratio is off — heads get cut, compositions break. Pick the format you need (4:5 post, 1:1 square, 9:16 story), and your image is center-cropped to the exact shape, then scaled to Instagram's pixel size. No squashing, no surprises, and the file never leaves your device.
