Getting thumbnails under 2MB
Use these before you upload or share the page.
Start at 1280x720px (YouTube's display resolution) — anything larger gets downscaled by YouTube anyway, wasting your file size budget.
JPEG at 75-80% quality usually lands a detailed thumbnail under 500KB, well within the 2MB limit with room for text overlays.
If your thumbnail has large solid-color areas, try PNG — it can be smaller than JPEG for flat graphics and text-heavy designs.
