About this Preset
Instagram supports three primary image ratios: Square (1:1, 1080x1080 px), Portrait (4:5, 1080x1350 px), and Fullscreen Story/Reel (9:16, 1080x1920 px). If you upload without adjusting your aspect ratio, Instagram auto-crops critical parts of your photo or applies heavy server compression that blurs details. Our converter lets you fit your photos into all three Instagram formats with smart centering or aesthetic background fills.
