Resize any image to 1280×720 pixels — the exact size a YouTube video thumbnail expects. Uploading a picture at the wrong dimensions gets it cropped or squashed by the platform; sizing it correctly first keeps your image looking exactly as you intended.
The correct YouTube thumbnail size
A YouTube thumbnail is 1280×720 pixels. Post an image at the wrong dimensions and the platform crops or squashes it, so part of your picture is lost or distorted. Sizing to 1280×720 pixels first means it fills the frame and displays exactly as you intended, every time.
Preview before you post
You see a preview before downloading, so you can confirm the important part of the image is kept within the 1280×720 pixels frame. Your image is uploaded to build the pack and deleted automatically an hour later, and platform dimensions are kept up to date.
