Frequently asked questions
What size is a YouTube thumbnail?
YouTube recommends 1280×720 pixels (16:9). The preset is built in — just select it and your image is cropped and resized automatically.
Will resizing make my image blurry?
Downscaling stays sharp. Upscaling a small image to a large canvas can soften it, so start with the highest-resolution original you have.
