FAQ
What size is a YouTube thumbnail?
YouTube recommends 1280×720 pixels (16:9) with a minimum width of 640 pixels and a maximum file size of 2 MB.
Do my images get uploaded to a server?
No. The resizer runs entirely in your browser using the Canvas API — your files never leave your device.
What formats can I upload and download?
Upload JPG, PNG, or WebP. Downloads keep the original format (JPG stays JPG, WebP stays WebP, everything else exports as PNG).
What size is a YouTube channel banner?
2560×1440 pixels, with the safe area for text and logos at 1546×423 in the center. This tool includes the banner size as a one-click preset.
