Introduction

A good image prompt does more than ask Gemini to make a picture “HD” or “4K.” It should explain what needs to be improved, how the image should look, which details must remain unchanged, and where the final image will be used.

You can use Gemini quality-enhancement prompts to sharpen portraits, improve lighting, restore old photographs, clean up backgrounds, enhance product images, correct colours, upscale visuals, and prepare images for websites or social media.

Gemini’s image tools may support different output sizes and aspect ratios depending on the model, product, account, and interface. In supported API workflows, image size can be specified separately from the creative prompt.

The prompts in this guide are designed for both image generation and image editing. You can copy and paste them into Gemini, then upload a photo when you want to enhance an existing image.

How to Make Images High Quality in Gemini

Use a high-quality source image

When editing an existing photograph, begin with the clearest original file available. A blurry, heavily compressed, or very small image may limit the quality of the final result.

Describe the exact improvement

Instead of writing only:

Make this image high quality.

Try:

Improve the sharpness, lighting, colour balance, and fine details while preserving the subject’s identity, facial features, clothing, pose, and background.

Mention the intended format

Add the required aspect ratio or use case:

• 1:1 for profile pictures and square posts.
• 4:5 for portrait social media posts.
• 9:16 for stories, reels, and mobile screens.
• 16:9 for YouTube thumbnails, presentations, and website banners.
• 3:2 for landscape photography.
• 2:3 for vertical photography.

Available aspect ratios and resolution controls may vary across Gemini products.

Protect important details

Use instructions such as:

Preserve the original face, identity, body shape, clothing, pose, product design, text, and overall composition.

You can also ask Gemini to make one change at a time. This makes it easier to identify which instruction improved or damaged the result.
