YouTube sizes in 2026
1280 x 720 pixels (16:9), JPG or PNG, under 2 MB. The time stamp covers the bottom right corner, so keep text away from it.
See it before you post
The preview shows your photo inside a mock of YouTube for home feed, up next, including the areas that get covered or cropped, so you can fix the framing before you upload.
Tip
Whole photo with AI fill is on by default, so a vertical or square photo becomes a full 16:9 thumbnail without cropping. Switch to Crop to fill if your photo is already wide.
Resize a whole batch
Drop many photos at once. Each one keeps its own crop position, and you can download them all as a ZIP. Everything runs in your browser, so nothing is uploaded.
