About GrabYTthumb
Who runs this site, how the tools work, and how we keep the guides accurate.
Who runs GrabYTthumb
GrabYTthumb is run by Rob Falconer through The AI Barn, which builds and maintains a number of small, free websites and web tools. The site is maintained from the UK, and that's where our copyright guidance starts from, though we also explain the US position where it differs.
GrabYTthumb is independent. It isn't affiliated with, endorsed by or sponsored by YouTube or Google. YouTube is a trademark of Google LLC, and we use the name only to describe what our tools work with.
What the site is for
The thumbnail downloader started as a simple utility: paste a link, get the image. Simple versions of that tool share a frustrating flaw. They show a grey placeholder whenever YouTube hasn't made a particular size, and leave you guessing. We rebuilt ours in October 2026 to check what YouTube actually returns and say clearly when a size doesn't exist.
Alongside the tools we publish guides on the questions that come up around thumbnails and uploads: what size to make a thumbnail, why the high-resolution version is sometimes missing, whether you can reuse one, and how to get chapters working.
How the tools work
- They're plain JavaScript that runs on your device. What you paste isn't sent to our server or stored.
- The thumbnail downloader loads images directly from YouTube's public image server. We don't host, copy or change thumbnails.
- There are no accounts, and no tracking beyond what's described in our privacy policy (advertising, with consent where the law requires it).
How we keep the guides accurate
- Facts about YouTube come from YouTube's own help pages, and each guide names its sources and the date we checked them.
- Where we've tested something ourselves, we say what we tested and when.
- We don't invent statistics, studies, quotes or testimonials.
- Every page shows a "Last updated" date. YouTube's rules change often, so if something is out of date, please tell us.
- Our copyright guide is general information, not legal advice, and says so.
How the site is funded
GrabYTthumb is free to use and is supported by Google AdSense advertising. Advertisers don't influence what we write.
