YouTube thumbnail blurry / pixelated — fix the low-res display
A YouTube thumbnail is showing up blurry / pixelated in your search results or homepage. The high-resolution version exists but YouTube is serving the smaller variant for some reason.
Why this happens
- YouTube's adaptive image serving picked a smaller variant for your viewport.
- Browser cache holds an old low-res version.
- Slow connection triggered low-res fallback.
- Older video that only has hqdefault (480×360) max — no maxres exists.
- The display is high-DPI but the layout doesn't request a higher-DPI variant.
How to fix it
- 1
Hard reload
Cmd+Shift+R. Re-requests images, may pick a higher-resolution variant for your current viewport.

Open the video — check the watch page
On the watch page, the thumbnail in search/results vs the actual high-res file may differ. Use our [/youtube-thumbnail-downloader](/youtube-thumbnail-downloader) to fetch the maxres version directly.

Confirm the video has maxres
Older videos may only have hqdefault (480×360). No matter what you do, that's the maximum stored size. Our thumbnail downloader shows you which sizes exist.
If you just want the video saved
For a guaranteed maxres thumbnail (when one exists), use the [/youtube-thumbnail-downloader](/youtube-thumbnail-downloader) tool. It shows the full size table and lets you save the actual largest available.
