How to resize an image to 1080x1080
- Choose or drop your images above.
- Keep “Crop to fill” for an exact 1080x1080 result, or pick “Fit inside” to avoid cropping.
- Download the resized files individually or as a ZIP.
About 1080x1080 pixels
A 1080x1080 image is square, with an aspect ratio of 1:1, and holds 1.17 megapixels. At 300 DPI it would print at about 3.6 x 3.6 inches (9.1 x 9.1 cm). As a JPEG it usually lands between 128KB and 256KB, depending on the picture and the quality you choose.
Where 1080x1080 is used
The standard square post size on Instagram. It also works well for Facebook, LinkedIn and X posts, where a square picture takes up plenty of space in the feed.
- Export from your editor at exactly this size, so the platform does not recompress and blur the picture.
- Keep key text and faces away from the edges, because apps crop and place buttons near them.
- Check the platform help page before you upload. Recommended sizes change from time to time.
Crop to fill or fit inside?
Crop to fill always gives exactly 1080x1080 by trimming the edges that do not match the shape. Fit inside keeps the whole picture and scales it so neither side exceeds 1080x1080, which can leave one side shorter. For a typical 4:3 phone photo, crop to fill removes about 25% of the picture. A 3:2 camera photo loses about 33%, a 16:9 screenshot about 44%, and a square image about 0%.
Quality and format
Check the result before you upload
Open the finished file and check three things: the picture measures 1080x1080, the subject is not cut off, and the file is small enough for where you upload it. If a platform sets a size limit, run the result through the online compression tool or choose a limit such as 200KB.
A tip for this size
Square crops keep the centre, so put your subject in the middle of the frame. Need another size? Try 1000x1000, 1080x1350, 600x600, the general image resizer, or browse every size preset.
Frequently asked questions
Why is my image not exactly 1080x1080?
You are probably using Fit inside, which never crops. Switch to Crop to fill for exact dimensions.
How big will a 1080x1080 file be?
As a JPEG, usually between 128KB and 256KB. Photos with lots of fine detail come out larger, and simple graphics smaller. Lower the quality for a smaller file.
Is 1080x1080 the right size for Instagram square posts?
It is a widely used size for Instagram square posts, but platforms and agencies change their rules. Check the current guidelines before you upload.
Will a small photo look blurry at 1080x1080?
If the original is smaller than this size, the tool has to enlarge it, and the result can look soft. Start from the largest version you have.
