Frequently Asked Questions

What is the recommended size and aspect ratio for YouTube thumbnails?
YouTube officially recommends a resolution of 1280 pixels wide by 720 pixels tall (16:9 aspect ratio), with a minimum width of 640 pixels, formatted as JPG, PNG, or WebP.
What is the maximum file size allowed for YouTube thumbnails?
YouTube enforces a strict 2MB file size ceiling for custom thumbnails on standard videos. Our tool automatically compresses graphics to meet this requirement without visible quality loss.
Where is the timestamp overlay positioned on YouTube thumbnails?
YouTube places the video duration timestamp in the bottom-right corner of the thumbnail. Keep text, logos, and critical subject elements clear of that corner.
Will this thumbnail size work on mobile and smart TVs as well?
Yes. The 1280x720 (16:9) standard scales down cleanly for mobile search results and scales up sharply for 4K smart TV displays.

No. OmegaTools never adds watermarks or branding to your images. All downloads are 100% free and ready for publishing.
