Answers focused on this tool. The homepage has a broader FAQ for the whole site.

Where do thumbnail images come from?: Standard i.ytimg.com URLs for the resolved video ID. We do not host the files; your browser loads them from YouTube’s CDN.
Why does max resolution return 404 for some videos?: Not every video has a maxresdefault asset generated. Use HQ or SD variants when the highest tier is missing.
How do JPEG resize exports work?: The selected CDN image is drawn to a canvas in your browser and exported at 16:9, 9:16, or 1:1 presets. If the browser blocks canvas reads, open the CDN URL and save manually.
Can I use thumbnails commercially?: You must comply with YouTube’s terms, the creator’s rights, and applicable copyright. This tool only exposes URLs YouTube already publishes for the video.
