What is the correct YouTube thumbnail size?

1280×720 pixels, 16:9 ratio, minimum 640px wide, under 2MB — this tool outputs exactly that.

Why does my thumbnail look blurry on YouTube?

Usually a small source image upscaled, or heavy compression. Start from a sharp 1280×720 image and it stays crisp.

My image is not 16:9 — what happens?

Resize handles the framing so the output is proper 16:9 instead of YouTube cropping it unpredictably.

What if the file is over 2MB?

Run Compress Image on the resized file — 1280×720 compresses well under 2MB at high quality.

The spec that matters

YouTube recommends 1280×720 (16:9). Upload a different shape and YouTube crops or letterboxes it — usually straight through the title text creators put near the edges. Resizing to spec first means what you design is what viewers see.

Sharp beats stretched

Blurry thumbnails come from upscaling small images or from non-16:9 sources being force-fitted. Start from your sharpest frame or design, resize to 1280×720 here, and keep text well inside the edges.

Mind the 2MB cap

YouTube rejects thumbnails over 2MB. If your design is heavy, run Compress Image after resizing — the target is easily met at 1280×720. Files are processed temporarily and deleted automatically — there is no general cloud storage.
