Resize Images for YouTube Thumbnails (1280×720)

Your thumbnail is a billboard in a feed of billboards. YouTube recommends 1280 × 720 pixels, 16:9 aspect ratio, under 2 MB. On a phone screen that's maybe 120 pixels wide, three words and one clear face beat a busy collage every time. The cooking channel with a shocked expression and one ingredient usually outperforms the one with six lines of tiny text.

Social Media Sizes crops to YouTube's preset. Need to nail a custom focal point first? Crop gives you more control over composition.

What actually gets clicks

One obvious subject — a face, a product, a reaction. Huge high-contrast text, three words max. Background that separates from YouTube's dark UI. And please, no misleading bait the video can't deliver; comment sections have long memories.

Place your subject on the left two-thirds. YouTube's timestamp sits bottom-right and will cover anything you put there.

From frame to upload

Start from a high-res still or an exported video frame — not a screenshot of a screenshot. Open Social Media Sizes, pick YouTube thumbnail, position your subject, download. Punch up brightness and contrast in Adjust so it reads on a small screen. Compress Image to stay under that 2 MB cap.

Shorts use vertical 9:16 — totally different crop. See Instagram Story crop for ratio tips on vertical video covers.

FAQ

YouTube says minimum 640px wide — is 1280 overkill?

640 is the floor. 1280 gives you clarity when YouTube scales down on different devices.

PNG or JPG for thumbnails?

JPG usually stays under 2 MB. PNG if you need razor-sharp text edges and file size isn't tight.

Will my text be readable on a TV?

Test at thumbnail size on your phone. Monitor "fit to window" previews are useless for this.

Can I reuse the same file for Shorts?

No — Shorts want 9:16 vertical. Different crop entirely.
