Frequently Asked Questions
What size should Instagram posts be?
Instagram supports three main post ratios: Square (1:1) at 1080×1080px, Portrait (4:5) at 1080×1350px — the recommended format for maximum feed space, and Landscape (1.91:1) at 1080×566px. Instagram will crop anything outside these ratios in the feed grid.
What size are Instagram Stories and Reels?
Instagram Stories and Reels are 1080×1920px (9:16 ratio). Keep important content in the center 1080×1420px zone to avoid UI overlays at top and bottom. Text and faces should be in the safe zone to ensure they're always visible.
Does Instagram compress images?
Yes — Instagram compresses images on upload. To minimize quality loss: upload at exactly 1080px wide (not larger), use sRGB color profile, and save as high-quality JPEG. PNG files may be converted to JPEG by Instagram anyway.
Is this Instagram resizer free?
Yes, fully free with no account required. Your images are processed locally in your browser — never uploaded anywhere.
