Resize any photo to Instagram's recommended dimensions: 1080x1080 for feed, 1080x1350 for portrait, 1080x1920 for stories. Free and instant.
Instagram crops or compresses photos that don't match its preferred aspect ratios. Your carefully composed landscape shot gets its edges chopped off in the feed. Story images look soft because Instagram re-compressed them. And each placement — feed square, portrait, story, reel cover — wants different pixel dimensions, so you end up guessing or opening Photoshop every time.
Our Image Resizer lets you pick a target size from preset Instagram dimensions or enter custom pixels. It handles the crop and resize in your browser without quality loss. Export as JPG or PNG, then upload straight to Instagram knowing every pixel is accounted for.
