Image resizer FAQ
How does an image resizer work?

Does resizing images affect image quality?
Yes, resizing an image affects its overall quality. However, using a high-resolution image that’s an appropriate size for the specific channel you’ll share it on (e.g., Facebook) should result in sufficient quality. When resizing web images, it’s best to stick with the standard resolution, i.e., 72 pixels per inch.
