Frequently Asked Questions
What size should a YouTube thumbnail be?
1280×720 pixels (16:9) is YouTube's recommended size, and it stays under the platform's file-size limit when saved as JPG or PNG.
Why is 16:9 important?
YouTube players and previews use a 16:9 frame. Matching it means no black bars or cropping on your thumbnail.
Should I export as JPG or PNG?
JPG keeps the file small for fast uploads; PNG is better if your thumbnail has sharp text or graphics.
Is my image uploaded?
No. Resizing happens in your browser.
