Resize Image to 1080x1080 — Free Online
Resize an image to 1080x1080 — the recommended square for Instagram feed posts. Type 1080 in width and height, unlock aspect ratio, and download.
Why 1080x1080?
Instagram displays feed posts at up to 1080 pixels wide. Square posts cropped at the source look sharper than letterboxed photos because the platform does not need to re-crop or pad.
Keep the subject centered
If your source is portrait or landscape, crop manually before resizing — otherwise the 1:1 stretch distorts proportions. Many phone galleries have a quick square crop.
Frequently asked questions
Does Instagram support sizes bigger than 1080?
Up to 1440 in some cases, but 1080 is the documented recommendation and gives the smallest file with no visible loss.
Is it actually free?
Yes. No signup, no daily cap on normal personal use, no watermark on the output. Display ads keep the site free.
Does it work on a phone?
Yes. The upload box opens the camera roll on mobile browsers directly.
