Frequently Asked Questions
What is the correct YouTube thumbnail size?
1280×720 pixels with a 16:9 aspect ratio, a minimum width of 640 px, and a file size under 2MB in JPG, PNG or GIF. This tool produces exactly that.
Why won't YouTube accept my thumbnail?
The most common reason is a file over 2MB. The resizer re-encodes the thumbnail automatically until it fits, while keeping it as sharp as possible.
What size is a YouTube channel banner?
2560×1440 px. Only the central 1546×423 px is visible on every device, so keep logos and text inside that safe area.
Do I need to upload my image anywhere?
No. Everything happens in your browser. Your thumbnail never leaves your device until you upload it to YouTube yourself.
