Professional Aspect Ratio Cropping

When preparing assets for a website layout or a specific social media feed, you cannot free-hand your crops. If an image is off by just a few pixels, it will break your CSS grid or get awkwardly stretched by Facebook's compression algorithm. Our Advanced Image Cropper allows you to lock strict aspect ratios before you cut.

Standard Aspect Ratios You Must Know

Locking your crop tool to these specific ratios ensures your images fit perfectly into their intended containers:

Frequently Asked Questions

What is the difference between Cropping and Resizing?

Cropping physically cuts away the outer edges of the image (discarding pixels). Resizing takes the entire original image and scales it down (or up) to a new dimension, changing the file size but keeping the entire composition intact.

Why does Instagram sometimes cut off the top of my photo?

If you upload a 9:16 (very tall) photo to the standard Instagram feed, they will force-crop it to a 4:5 ratio (slightly shorter). You must crop it to 4:5 yourself before uploading to control exactly what gets cut off.

Does cropping reduce the file size (megabytes)?

Yes. By removing thousands of pixels from the edges of the image, the total amount of data the file must store is reduced, resulting in a smaller file size.
