About the Instagram Image Resizer tool
When a photo isn't the right shape, Instagram crops it for you — often cutting off heads, text or products. Resizing it yourself first means you choose exactly what's in the frame. Portrait 1080 × 1350 takes up the most space in people's feeds, which usually means more attention for your post.

Frequently asked questions
What's the best image size for Instagram?
1080 × 1350 pixels (portrait, 4:5) for feed posts, because it takes up the most screen space. Use 1080 × 1080 for square posts and 1080 × 1920 for Stories and Reels.
Why does Instagram make my photos blurry?
Instagram re-compresses large photos. Uploading at exactly 1080 pixels wide helps keep them sharp.
Can I use it for other social networks?
Yes. Square and portrait sizes also work well for Facebook, Threads and LinkedIn posts.
Is it free?
Yes. No watermark, no sign-up, and your photos never leave your device.
