Resize for Instagram
Scale and centre-crop any photo to Instagram's exact dimensions — 1080×1080, 1080×1350, 1080×566 or 1080×1920 — in your browser.
About this tool
Instagram re-encodes and crops anything that does not match its accepted proportions, which is where the soft, over-compressed look comes from. Feeding it an image that already has the right dimensions avoids most of that.
This is the resize tool with Instagram's formats preset: 1080×1080 square, 1080×1350 portrait — the format that occupies the most screen height in the feed — 1080×566 landscape, and 1080×1920 for Stories and Reels. Pick one and the image is scaled and centre-cropped to fit it exactly.
For any other dimensions, use the general resizer, and see crop if you want to control the framing by hand rather than from the centre.

Frequently asked questions
What size should an Instagram post be?
Upload at 1080 px wide. Square posts are 1080×1080, portrait posts 1080×1350, landscape posts 1080×566, and Stories and Reels 1080×1920. Portrait takes up the most space in the feed, which is why most accounts default to it.
Why does Instagram make my photos look bad?
It re-encodes every upload, and it resizes anything that is not 1080 px wide — resizing an already-compressed image and then compressing it again is what produces the mushy result. Uploading at exactly 1080 px wide removes one of those two steps.
Should I upload larger than 1080 px?
There is little benefit. Instagram scales down to 1080 px wide for the feed regardless, so a 4000 px upload just means their encoder does the downscale instead of yours, with less control over the result.
Does this crop or squash my photo?
It crops from the centre, never squashes: the image is scaled until it covers the target frame and the overflow is trimmed, so proportions stay correct. If the crop cuts something important, use the crop tool to choose the framing yourself first.
