Open Resize Image to 1080×1080Why 1080×1080 is the sweet spot
Instagram stores and displays feed images at up to 1080px on the squarer axis. Publishing larger gains nothing (Instagram downscales) and publishing smaller uploads a blurrier file. 1080×1080 hits the exact ceiling.
Resize in two clicks
- Open the Resize Image tool.
- Drop your photo.
- Enter 1080 as width and 1080 as height (aspect ratio locked).
- Download your JPEG or PNG at 1080×1080.
Keep the aspect ratio lock on so faces and products are never stretched. For a directly-cropping square, use the Crop tool first.
Square without distortion
If your original is not square, lock the aspect-ratio and the tool fits within 1080×1080, or crop to square first with the Crop tool for a guaranteed full-bleed post.

Will 1080×1080 look sharp?
Yes — it exactly matches Instagram's maximum, so there is no upscaling or downscaling on their side.
Does resizing affect image quality?
Downscaling to 1080 rarely shows visible loss. Export as PNG for text-heavy graphics or JPG 85% for photos.
