Frequently asked questions
What is the best Instagram Square Post size?
Square 1080 × 1080 pixel images display consistently in the feed and in profile grids.
What aspect ratio is it?
1:1, which is 1080 × 1080 pixels.
Is my image uploaded?
No. Resizing and cropping happen in your browser, so your image stays on your device.
Which file type should I use?
JPG is best for photos and keeps files small. PNG keeps text, logos and screenshots sharp.
Will the image be cropped?
By default the tool crops to fill the exact shape. Choose the whole-image option to keep everything and pad the sides with white.
Can I make the file smaller?
Yes. Use the compress-to-KB tools afterwards if a platform limits file size.
Do platforms change these sizes?
Sometimes. Recommended sizes are updated from time to time, so check the platform's help page if your image looks soft or cropped.
