Turn Blurry and Low-Resolution Photos into Perfect 4K Quality with InVideo AI

Have you ever found an old photo that means a lot to you, but the quality is just… painful to look at? The image is blurry, details are missing, and when you zoom in, everything breaks apart. It’s frustrating, especially when that photo captures an important moment you can’t recreate.

The good news is, you don’t need to be a professional editor or own expensive software anymore. With the help of InVideo AI, you can transform blurry and low-resolution photos into clean, sharp, true-to-life 4K images in just a few minutes. No complicated settings, no technical headaches.

What makes this even better is how natural the results look. The face stays the same. The expression doesn’t change. There’s no weird AI “plastic skin” effect. It simply looks like your original photo, but clearer, sharper, and higher resolution.

In this article, I’ll walk you through the exact steps to upgrade your photo quality to 4K using InVideo AI, using a powerful prompt that keeps every detail faithful to the original image. Let’s get straight into it.

How to Enhance Blurry and Low-Resolution Photos to 4K Using InVideo AI

Before we start, you need to know one thing. InVideo AI is not just a video tool. It also comes with advanced generative image models that are incredibly good at photo enhancement, especially when paired with the right prompt.

Here’s how you can do it step by step.

Step 1: Open InVideo AI and Log In

First, open your browser and access the official InVideo AI website. You can use this direct link to simply access it:
https://invideo.io/i/MakeItSimple

Once the page loads, log in using your account. If you don’t have one yet, just sign up. The process is quick and straightforward.

Step 2: Go to “Agents and Models”

After logging in, look for the Agents and models menu. This section is where InVideo AI keeps all its AI-powered tools and models, including the image generation and enhancement features.

Tap on Agents and models to continue.

Step 3: Tap “See All” on Generative Models

Inside the menu, you’ll see several categories. Find Generative models, then tap See all. This will show you the full list of available AI models you can use.

This step is important because the quality of the final result depends heavily on the model you choose.

Step 4: Open Image Generation Models

Next, look for the Image generation category and open it. This is where InVideo AI’s image-focused models live, including those designed for enhancement and upscaling.

Step 5: Choose the Nano Banana Pro Model

From the available options, select Nano Banana Pro.
This model is excellent for high-resolution enhancement while maintaining facial accuracy and realistic textures. It’s the key to getting a clean 4K result without altering the original identity.

Step 6: Create a New Project

Once the model is selected, create a new project. This gives you a fresh workspace where you can upload your photo and apply the enhancement.

Step 7: Upload Your Blurry or Low-Resolution Photo

Now, upload the photo you want to improve. It can be blurry, pixelated, or low resolution. The AI will use this image as a strict reference, so choose the best original version you have.

Step 8: Paste and Use This Enhancement Prompt

This is the most important part. Copy and paste the following prompt exactly as it is:

Ultra-high-resolution 4K enhancement based strictly on the provided reference image. Absolute fidelity to original facial anatomy, proportions, and identity. Preserve expression, gaze, pose, camera angle, framing, and perspective with zero deviation. Clothing, hair, skin, and background elements must remain unchanged in structure, placement, and design.

Recover fine-grain detail with natural realism. Enhance pores, fine lines, hair strands, eyelashes, fabric weave, seams, and material edges without introducing stylization. Maintain original color science, white balance, and tonal relationships exactly as captured. Lighting direction, intensity, contrast, and shadow behavior must match the source image precisely, with only improved clarity and expanded dynamic range. No relighting, no reshaping. Remove any grain.

Apply controlled sharpening and high-frequency detail reconstruction. Remove compression artifacts and noise while retaining authentic texture. No smoothing, no plastic skin, no artificial gloss. Facial features must remain consistent across the entire image with coherent anatomy and clean, stable edges.

Negative constraints: no warping, no facial drift, no added or missing anatomy, no altered hands, no distortions, no perspective shift, no text or graphics, no hallucinated detail, no stylized rendering. Output must read as a true-to-life, photorealistic upscale that matches the reference exactly, only clearer, sharper, and higher resolution.

This prompt tells the AI to enhance only the clarity and resolution, without changing any facial features, lighting, or composition.

Step 9: Adjust Aspect Ratio Settings

Go to Settings and choose Keep Original Aspect Ratio.
This ensures the photo doesn’t get cropped or stretched. If you want to experiment with other aspect ratios, you can, but keeping the original is the safest choice.

Step 10: Set Resolution to 4K

Still in the settings menu, select the output resolution and choose 4K.
This is what gives you that ultra-sharp final image.

Step 11: Click Generate and Wait

Click Generate, then wait a few seconds. The processing time is usually fast, depending on image size and server load.

Step 12: Download Your Enhanced 4K Photo

And that’s it. Your once-blurry photo is now clean, sharp, and detailed, with no broken pixels and no changes to the face or identity. Simply download it to your gallery and enjoy the result.

Conclusion

Enhancing blurry and low-resolution photos no longer requires complex software or advanced editing skills. With InVideo AI, you can upgrade your images to true 4K quality while keeping every detail faithful to the original photo.

The combination of the Nano Banana Pro model and a precise enhancement prompt ensures that your face, expression, lighting, and composition remain untouched. The result looks natural, realistic, and clean, not artificial or overprocessed.

If you have old memories, important portraits, or photos that deserve a second life in higher quality, this method is absolutely worth trying. It’s fast, effective, and surprisingly easy, even for beginners.

Give it a shot, and see how much better your photos can look with just a few clicks.
