How I use the Image Resizer

I upload the image, type the width I need, 1280 for a YouTube thumbnail, 1080 for an Instagram square, and download. Aspect lock stays on unless I'm cropping deliberately.

I resize before I upload, not after. Platforms compress again anyway, so starting at the right size keeps things sharp.
