YouTube thumbnail downloader

Paste a YouTube link or id and get every thumbnail size that exists, plus 16:9, square, and vertical crops, a card mock preview, and batch ZIP downloads.

This tool is in beta

Still being tested. If a result looks wrong, tell us.

Report a problem

Paste one or more videos and press Get thumbnails

Every thumbnail size YouTube serves is checked live. Missing sizes, the grey 120 pixel placeholder, and 404s are listed as missing instead of pretending.

Downloads are re-encoded from the decoded pixels (PNG, or the crop format you picked), because a browser cannot save a cross-origin file under its original bytes. Copy URL hands you the original link instead. sddefault is 4:3 letterboxed on most videos, so the crop tool is the honest way to a clean 1:1 or 9:16 piece. The mock preview approximates where YouTube paints the title, progress bar, and duration badge; it is a planning aid, not the platform spec. Private and deleted videos have no thumbnails, and nothing here pretends otherwise.

What leaves your browser

When you press the button, this page asks YouTube's public image server (i.ytimg.com) directly for each thumbnail size. The video ids never reach any Nutter Tools server. This page leaves your browser only when you press the button; never on load, never in the background. Nothing is sent anywhere else. Google Analytics still measures the visit to this page, and it never receives what you run through this tool.

Runs on this device. Nothing is uploaded.
