What is the recommended YouTube thumbnail size?

YouTube recommends 1280x720 pixels (16:9 aspect ratio) with a file size under 2MB. This tool matches those specs exactly.

Can I use images that aren't 16:9?

Yes. For a single image, you can adjust the 16:9 crop area manually. For multiple images, center-crop is applied automatically.

What happens if my image is larger than 2MB?

After cropping and resizing, the tool auto-compresses while preserving as much quality as possible to stay under 2MB.

Will the quality drop noticeably?

At 1280x720, quality loss is typically imperceptible. Only very large originals may show a slight difference.

Should I choose JPG or WebP?

JPG has the widest compatibility. WebP offers smaller file sizes at the same quality. YouTube accepts both.

Are my files sent to a server?

No. Everything is processed in your browser. Files are never uploaded to any server and are released when you close the tab.

How many images can I process at once?

Up to 20 images on desktop and 5 on mobile devices.

What about images with a transparent background (PNG)?

If you choose JPG, transparent areas become white. Choose WebP to keep transparency.

Can I make Shorts thumbnails here?

This tool is for standard YouTube thumbnails (16:9). For Shorts (9:16), use the Shorts Cover Resize tool.
