Frequently Asked Questions
What is the best size for Instagram posts?
For regular Instagram feed posts, 1080 x 1080 pixels (square, 1:1 aspect ratio) is the classic and most versatile size. However, portrait images at 1080 x 1350 pixels (4:5 aspect ratio) take up more screen space on mobile devices and often perform better. For Stories and Reels, always use 1080 x 1920 pixels (9:16 aspect ratio).
Why does Instagram crop my photos?
Instagram crops photos that don't match its supported aspect ratios. If you upload an image that's too wide, too tall, or an unusual shape, Instagram automatically crops it. Using our tool to resize beforehand lets you control exactly how your image is cropped.
Are my images safe when using this tool?
Yes, completely safe! All image processing happens in your browser using JavaScript. Your images are never uploaded to any server or stored anywhere. This ensures complete privacy.
