Create the cut-out style
- Take a still frame or a photo with a clear expression.
- In Change background pick a bold gradient or upload your own background image.
- Set the size to 16:9, add a soft shadow so the subject stands out, and download.
- Add text in your design app if needed, then check that the file is 1280 × 720 — use Resize image → YouTube preset.
What makes a thumbnail work
- One clear focal point: a face with emotion or the key object.
- High contrast between subject and background.
- Few words, large letters — thumbnails are often seen tiny on phones.
- The bottom-right corner shows the video length, so keep important elements away from it.
Frequently asked questions
Why is my thumbnail rejected?
The most common reason is a file over 2 MB. Save as JPG or compress the PNG.
