Frequently Asked Questions
What is the ideal YouTube thumbnail size?
The ideal YouTube thumbnail size is 1280×720 pixels (16:9 ratio). YouTube also accepts 1920×1080 (full HD) thumbnails. The minimum width is 640px. YouTube requires thumbnails under 2MB and accepts JPG, GIF, BMP, or PNG formats.
What makes a YouTube thumbnail perform well?
High-performing YouTube thumbnails typically have: a close-up face showing a strong emotion, bold and easy-to-read text (3–5 words max), high contrast so they stand out against white backgrounds, a cohesive visual brand identity, and they accurately represent the video content to minimize bounce-back.
Can I use this to make thumbnails from screenshots?
Absolutely — screenshot a key moment from your video, upload it here, and it'll be resized to the exact 1280×720 dimensions YouTube requires. You can use Cover mode to fill the full frame or Contain to preserve the full screenshot with background padding.
