Instagram Post Cropper

Crop single posts or an entire carousel to 3:4, 4:5, square or landscape. See exactly how much of the source survives, preview the 3:4 profile grid, harmonize up to 20 images, and export a posting-order ZIP locally.

3:4 grid survivalPreviews the current 3:4 profile-grid presentation so edge text and faces do not surprise you later.

Crop-loss meterCalculates how much source area survives the selected crop instead of hiding the cost of a ratio change.

Carousel harmonizerLoad multiple photos, crop each independently to one ratio, and export numbered files in posting order.
