YouTube Thumbnail Downloader
Preview a video's thumbnail at every available size, confirm its true resolution, and save the original file — no compression, no watermark, no account.
Download a thumbnail
Works with watch links, Shorts, live streams, embeds, and youtu.be links.
Direct programmatic downloads are blocked by YouTube's image servers (no CORS headers). The reliable way is Open in new tab → Save image as, which keeps the original file untouched.
How it works
How the thumbnail downloader works
Pick a size
Five sizes are checked: maxresdefault (1280×720, when it exists), sddefault (640×480), hqdefault (480×360), mqdefault (320×180), and default (120×90).
See the real resolution
Each file is loaded and its actual pixel dimensions are read. If a size is missing — common for maxres and sd — it's flagged instead of shown as a grey box.
Save it
Open the size in a new tab and use your browser's Save image as. What you save is the exact original file — never re-encoded by this tool.
Questions
Thumbnail downloader FAQ
How do I download a YouTube thumbnail in HD?
Paste the video link, pick a size tab (maxresdefault is the highest at 1280×720 when it exists), then click Open in new tab and choose Save image as. The tool always shows the real resolution the file is served at.
Why does my download come out grey or tiny?
maxresdefault and sddefault are not generated for every video. When a size is missing YouTube serves a 120×90 grey placeholder instead of an error, so the downloader checks each file's real dimensions and flags missing sizes.
Why is there no direct download button?
YouTube's image servers do not send CORS headers, so browsers block scripts from reading the image pixels and forcing a download. Opening the image in a new tab and using Save image as always works and keeps the original quality untouched.
Is the thumbnail downloader free?
Yes. Every tool on AntigleForge is free and runs entirely in your browser. Nothing is uploaded, stored, or processed on a server.
