Instagram Post size: 1080×1080
Instagram displays feed posts as a 1:1 square, so a 1080×1080 image avoids awkward auto-cropping.
How to resize for Instagram Post
- Open the resizer below and drop in your image.
- Enter a width of 1080 and height of 1080 pixels.
- Preview, then download — your image is now ready for Instagram Post.
Tips
- If your source has a different aspect ratio, crop it to 1080×1080's shape first to avoid stretching.
- Start from the highest-resolution original you have; you can shrink without quality loss, but enlarging adds blur.
- All processing is local — your photo is never uploaded.
