Part 1: What is Image Resolution and Why 4K Resolution Matters

Image resolution refers to the number of pixels contained in an image, typically expressed as width x height. It determines the level of detail and clarity in an image. Higher resolution means more pixels, resulting in a sharper and more detailed image.

4K resolution, also known as Ultra HD (UHD), is a specific image resolution that has gained popularity in recent years. It refers to a display or image resolution that measures approximately 3840 pixels wide by 2160 pixels high. The term "4K" comes from the horizontal pixel count being close to 4,000 pixels. With four times the number of pixels compared to standard HD resolution, 4K resolution offers exceptional image sharpness, clarity, and detail. As 4K displays and devices become increasingly common, ensuring your images are optimized for this resolution becomes crucial for showcasing your work effectively.

Part 2: Can I Convert Images to 4K by Manually Changing Pixels?

Manually changing the pixel dimensions of an image without utilizing advanced algorithms or techniques will not truly upscale the image to 4K resolution. Simply increasing the pixel count without proper interpolation or enhancement methods will result in a larger image with no added detail or improvement in quality.

To achieve a genuine 4K resolution, advanced upscaling techniques are necessary. These techniques involve analyzing the existing image content and using interpolation algorithms, machine learning, or artificial intelligence to intelligently generate new pixels and enhance the level of detail while preserving image quality during the upscaling process.

Manually changing pixel values without employing such techniques will only result in a larger image that may appear pixelated or blurry, as the original details are not preserved or enhanced. To achieve the best results when upscaling to 4K resolution, it is recommended to use specialized software or tools that employ advanced algorithms specifically designed for upscaling images.

Step 3: Apply the AI Upscale Model

On the left side of the AVCLabs PhotoPro AI interface, you will find seven different AI models to choose from. To convert your images to 4K resolution, select the "Upscale" model. Click on it and explore the available magnification levels, including 1X, 2X, 3X, and 4X. For true 4K conversion, opt for the 4X magnification level.

These magnification levels represent the scaling factor applied to your image. It will double, triple, and quadruple the original size of the input image. Importantly, this process maintains the image's details without any loss. The maximum size supported for upscaling is 8K.

Step 4: Export the Processed Photo

Once the conversion process is complete, you can preview the original and converted 4K images side by side by clicking on the "Contrast" button. If you're satisfied with the results, save the converted image to your local disk for further use or sharing.
