JPG, PNG, WEBP · multiple files at once
Your files stay in your browser. Nothing is uploaded.
1280×720 is the size YouTube asks for, and the reason is arithmetic rather than taste: it is exactly 16:9, so it drops into every player, sidebar and recommendation strip without letterboxing. Upload something in a different shape and YouTube crops it for you, usually across the part you cared about.
Design for the smallest version
Your thumbnail is judged at about 210 pixels wide in the sidebar and smaller still on a phone. Whatever you put in it has to survive being shrunk to a sixth of its size, which in practice means very few words, very large, with strong contrast against the background. Text that reads comfortably at full size often turns to mush in the feed.
Two things that get clipped
The duration badge sits in the bottom-right corner, and the progress bar covers the bottom edge once a viewer has started watching. Keep faces and text away from both. YouTube also caps thumbnail uploads at 2 MB, so compress the result if it comes out heavy — at this resolution that is rarely a problem.

Frequently asked questions
- Can I upload a thumbnail larger than 1280×720?
- Yes, as long as it stays 16:9. YouTube scales it down, and 1280×720 is the smallest size that still counts as HD.
- Why does my thumbnail look blurry in the feed?
- Usually detail, not resolution — small text and busy backgrounds fall apart once the image is displayed at around 210 pixels wide.
- What file size does YouTube allow?
- Up to 2 MB per thumbnail. If yours is over, compress it before uploading.
