Frequently Asked Questions

Everything you need to know about optimizing images for Google Discover.

What is the best image size for Google Discover?

The best image size for Google Discover is 1280×720 pixels (16:9 aspect ratio). Google requires a minimum width of 1200 pixels and at least 300,000 total pixels. For best results, use 1600×900 pixels in WebP format.

How do I add max-image-preview:large meta tag to my blog?

Add <meta name="robots" content="max-image-preview:large"> to the <head> of every page. This tells Google to display large image previews in Discover feed. Without this tag, your images may not appear in Google Discover at all.

Is DiscoverImg free to use?

Yes, DiscoverImg is 100% free for individual bloggers. You can check Discover scores, resize images, convert to WebP, preview Discover cards, and generate meta tags without any signup. All processing happens in your browser — your images never leave your device.

Why are my blog images not showing in Google Discover?

The most common reasons are: (1) Images are smaller than 1200px width, (2) Missing max-image-preview:large meta tag, (3) Images are in heavy JPEG/PNG format instead of WebP, (4) Low image quality or stock photos. Use DiscoverImg to check and fix all these issues instantly.

What image format is best for Google Discover in 2026?

WebP is the best image format for Google Discover in 2026. It offers 25-35% smaller file sizes than JPEG with the same visual quality, leading to faster page loads and better Core Web Vitals scores. AVIF is even better but has limited browser support.
