Images are typically the largest assets on any webpage. Optimizing them is the single most impactful thing you can do for page load speed. ImgGPT gives you every tool you need.

Favicon Generation

Every website needs a favicon. Upload your logo and ImgGPT generates all six sizes (16px to 256px) at once. Drop them in your public directory and add the link tags to your HTML head.

For Next.js and other React frameworks, the generated PNGs in the public directory are detected automatically.

WebP and AVIF Conversion

If you are still serving JPG and PNG, you are leaving performance on the table.

  • WebP reduces file size by 25-30% compared to JPG at equivalent quality. Supported by every modern browser.
  • AVIF reduces size by 50% compared to JPG. Support is growing rapidly — Chrome, Firefox, and Safari all support it now.

Use ImgGPT's converter to batch-convert your image assets. For maximum compatibility, serve WebP with a JPG fallback using the picture element.

Compression Best Practices

Run every image through the compressor before deploying. Target quality 80 for WebP. The visual difference is imperceptible, but the file size difference is dramatic.

Impact on Core Web Vitals

Google's Largest Contentful Paint (LCP) measures how quickly the main content loads. Images are the most common LCP element. Properly compressed and sized images can improve your LCP by seconds.

A hero image at 200 KB loads in under 1 second on a 3G connection. The same image at 2 MB takes over 10 seconds.

Responsive Image Sizing

Do not serve a 3840px image to a mobile viewport that is 375px wide. Use the Resize tool to generate multiple sizes:

  • 640px for mobile
  • 1024px for tablet
  • 1920px for desktop

Then use srcset in your img tags to serve the right size to each device.

CDN Hosting

On a paid plan, every image saved to a project gets a Cloudflare CDN URL. Use these URLs directly in your HTML. No need to manage image hosting separately.

The CDN handles global distribution, caching, and fast delivery automatically.

ImgGPT is the image pipeline that most web projects need but few set up properly.
