Frequently Asked Questions

What is the best aspect ratio for Instagram?

Instagram supports multiple ratios: 1:1 for square posts (1080x1080px), 4:5 for portrait posts (1080x1350px), and 9:16 for Stories and Reels. Use our Social Media Image Resizer for exact dimensions.

Can I crop an image to exact pixel dimensions?

Yes. Use the FreeForm option to manually select your crop area, then resize the result to exact dimensions using our Image Resizer tool.

Does cropping reduce image quality?

Cropping removes pixels from the edges, so the resulting image has fewer total pixels. However, the remaining pixels retain their original quality — no blurring or compression is applied.

Is cropping the same as resizing?

No. Cropping removes parts of an image to change its composition. Resizing changes the dimensions of the entire image. You can use both tools together for perfect results.
