YouTube Image Resize
For most YouTube content workflows, 1280×720px (16:9 HD) is the universal size for everything except channel art (2560×1440), end screens (1920×1080), and profile (800×800). It covers custom thumbnails, Community tab posts, in-video overlays, Shorts covers, and Premiere standby screens with the same crop. Compared to 1920×1080 (Full HD), it is ~56% of the pixels but at typical mobile viewing size the visual difference is barely perceptible — and the smaller weight is better for the 2MB thumbnail cap and faster Community-image loading. This tool exports a single 1280×720px JPG, with the bigger payoff being one unified master that powers thumbnails, community posts, and in-video overlays at once.
How to use
Check sidebar 246×138 readability
Account for the same crop appearing as small as ~246×138px in the suggested-video sidebar — center subjects and key text so they survive that scale.
Stay under 2MB JPG
Export as 1280×720px JPG under 2MB (custom thumbnails are rejected above 2MB).
When to use this tool
Reusing the same 1280×720px master across thumbnails, Community posts, and in-video overlays keeps your visual tone consistent — viewers spot a series faster, and series-level watch time tends to climb.
