Quick Tool Overview

Crop Image to Aspect Ratio locks the crop frame to the exact shape you are publishing to, so what you see is what ships. Presets cover 1:1, 4:5, 16:9, 9:16, 3:2 and 2:3, and any other ratio can be typed in. The frame opens at the largest crop the ratio allows, centred, which is usually most of the way to the answer.

About the Crop Image to Aspect Ratio

Every platform wants a different shape, and getting it wrong is what produces the awkward automatic crop that cuts someone's head off. Pick the ratio you are publishing to and the frame is constrained to it, so the crop you see is exactly the crop that ships.

The presets cover the ratios that actually come up — 1:1 for a square post, 4:5 for the tallest shape a feed will accept, 16:9 for video thumbnails and slides, 9:16 for stories and reels, 3:2 and 2:3 for photographic prints. Any other ratio can be typed in directly. The frame defaults to the largest crop the ratio allows, centred, which is usually most of the way there before you have touched anything.

Key features of the Crop Image to Aspect Ratio

Presets for the ratios that matter

Square, 4:5 feed, 16:9 thumbnail, 9:16 story, 3:2 and 2:3 print — one click each, no arithmetic.

Custom ratios

Type any two numbers, such as 21:9 or 1.85:1, and the frame locks to that shape immediately.

Starts from the best fit

The frame opens as the largest crop the ratio allows, centred, so a lot of images need no adjustment at all.

No resampling

Cropping only discards pixels outside the frame. The kept area stays at its original resolution and sharpness.

Current ratio shown

The image's existing ratio is displayed on load, so you can see how much reshaping the target actually needs.
