🧭 How It Works (Step-by-Step Guide)

Step 1: Generate an Image in ChatGPT

Start by asking ChatGPT to generate an image using any prompt — for example:

“Generate a YouTube thumbnail for a Dog Care video.”

You’ll see the generated image appear inside ChatGPT.

Step 2: Click “Resize This Image”

Right below the generated image, you’ll find a purple button that says “Resize this image.”
Click it — and the Image Resizer for ChatGPT popup will open automatically.

Step 3: Customize and Resize

Inside the popup, you can:

• Select a preset (e.g. YouTube Thumbnail 1280×720, Instagram 1080×1080, etc.)
• Choose a background color (useful when aspect ratios don’t match)
• Pick image format (JPG or WebP)
• Adjust quality with a simple slider
• Rename your image with automatic tokens like {name}_{preset}

When ready, click “Resize & Download” — and your perfectly sized image will be instantly ready for use!

💡 Pro Tips

• Use Contain mode for keeping full image visibility.
• Use Cover (crop) when you want edge-to-edge visuals for thumbnails or banners.
• Select WebP format for smaller, faster-loading images on the web.
• Want to reuse your resized images? Check “Bundle into ZIP” to download them together.
