FAQ
What size does the tool export?
The output is 1280 x 720 pixels, the standard YouTube thumbnail size.
Why do I see a 16:9 warning?
The warning appears when your source image is noticeably different from 16:9, which usually means cropping will produce a better thumbnail.
Can I export as JPG, PNG, or WebP?
Yes. All three formats are available and processed locally in your browser.
