How to resize a photo for Instagram

   Pick where it goes

   Portrait post, 4:5 post, square, landscape, Story / Reels, Reels cover or profile picture. The frame changes shape right away.

3. 3

   Move the frame

   Move and resize the frame with your mouse or finger until everything important is inside. The aspect ratio stays locked.

4. 4

   Download the JPG

   Click Crop for Instagram, download the JPG and post it from the Instagram app. summer.heic becomes summer-cropped.jpg.

Want the whole photo with no crop?

This page always crops, it cannot add borders. If your photo is already between 1.91:1 and 3:4, Instagram keeps it whole, and Resize image shrinks it to 1080 px wide without cutting anything off. A taller or wider photo only fits whole as a post with white or colored bars added in another app.

Instagram post size in 2026

Instagram stores photos up to 1080 px wide and keeps the full photo when the aspect ratio is between 1.91:1 and 3:4. That means 1080 × 1440 px for a 3:4 portrait post, 1080 × 1350 px for 4:5, 1080 × 1080 px for a square and 1080 × 566 px for a 1.91:1 landscape post. With a large enough crop, this page saves exactly those sizes.

3:4 is now the tallest post format, taller than the 4:5 that many older guides still recommend. Instagram enlarges photos narrower than 320 px and scales down anything wider than 1080 px, so a sharp post starts with a crop at least 1080 px wide.

How to post a whole photo on Instagram without cropping

First check the shape. A photo between 1.91:1 and 3:4, such as a 4:5 shot or a square, goes up whole. Shrink it to 1080 px wide with the Width setting on Resize image, and nothing is cut off.

A taller photo, such as a 9:16 phone shot or a 2:3 portrait from a camera, does not fit whole as a post. Post it as a Story, crop it to 3:4 here and choose what stays, or add white bars in an editing app. None of the tools on this site add borders.

Instagram Story, Reels cover and profile picture size

Story / Reels saves a 9:16 photo at up to 1080 × 1920 px, the full height of a phone screen. Reels cover saves up to 420 × 654 px, and Profile picture makes a square of up to 1080 × 1080 px. A smaller crop stays smaller.

Instagram shows the profile picture in a circle, so keep the face in the middle with some room around it. You do not need to upload a round PNG.
