What's the recommended size for a YouTube thumbnail?

YouTube recommends a resolution of 1280×720 px (HD) with a 16:9 aspect ratio. The maximum file size is 2 MB. Accepted formats are JPG, GIF, BMP and PNG.

What's the difference between Cover and Contain mode?

Cover mode entirely fills the 1280×720 px frame — the image is scaled up to cover the whole surface, and the parts overflowing the edges are cropped. Contain mode keeps the entire image inside the frame, without cropping — empty areas are filled with a background (color or blur).

Are my images sent to a server?

No. All processing happens directly in your browser via JavaScript's Canvas API. No file is sent to our servers.

What's the difference between JPG and PNG for a YouTube thumbnail?

JPG is compressed (92% quality) — smaller file size, perfect for the web and for YouTube, which recompresses anyway. PNG is lossless — maximum quality, heavier file. For a YouTube thumbnail, JPG is generally sufficient.
