How to Resize to 1080 × 1080
- Upload one or more images
- Instagram Post (1080x1080) is already selected, so by default every image comes out at exactly 1080 × 1080 pixels — an image with a different shape is stretched to fill it
- To keep an image's proportions instead, tick Maintain aspect ratio: it then fits inside 1080 × 1080 without stretching, so one side can come out smaller
- Open Fine-tune to change the output format or quality
- Read the real output size, then download files individually or once as a ZIP
Features

Frequently Asked Questions
What size should Instagram photos be?
Instagram posts are best at 1080x1080 pixels (square) or 1080x1350 (portrait). Stories and Reels should be 1080x1920 pixels (9:16 aspect ratio).
What happens if my photo is the wrong size?
Instagram will crop or letterbox your photo. Resizing here uses the exact 1080x1080 size by default, so a photo of another shape is stretched to fill the square. Tick "Maintain aspect ratio" to keep its proportions instead; it then fits inside 1080x1080 and one side comes out smaller.
What is the best aspect ratio for Instagram?
Square (1:1) for posts, Portrait (4:5) for taller posts, and 9:16 for Stories and Reels.
