Tips for Using Aspect Ratios
Social Media
Use 1:1 for Instagram posts, 9:16 for Stories, and 16:9 for YouTube thumbnails.
Website Banners
16:9 is ideal for website headers and banners, while 4:3 works well for product images.

Frequently Asked Questions
Aspect ratio is the proportional relationship between an image's width and height, expressed as two numbers separated by a colon (e.g., 16:9).
Cropping removes parts of the image to fit the new ratio, while letterboxing adds black bars to the top/bottom or sides to maintain the original image content.
Our tool maintains the original image quality. Only cropping removes pixels, while letterboxing and stretching preserve all original pixels.
Our aspect ratio changer supports JPEG, PNG, WebP, GIF, and BMP image formats.
