How to Convert Image to High Resolution 4K/8K/16K/32K?

Image resolution refers to the number of pixels packed into a digital image. The higher the resolution, the sharper and clearer the details appear. Conversely, low-resolution images exhibit a blocky, pixelated appearance. So, to increase image crispness and sharpness, you need to convert low-resolution images to high-resolution with more pixels and details.

This article explores several methods to help you increase image resolution to enhance image quality for printing, uploading, or advertisement, and restore old photos.

Way 1. Convert Image to High Resolution with Aiarty Image Enhancer

Aiarty Image Enhancer is an AI-powered image enhancer that offers 4-in-1 image enhancement capabilities. With just a single click, you can upscale your images by converting images to high resolution, like 1K, 2K, 4K, or 8K. Also, while increasing image resolution, Aiarty Image Enhancer will automatically start the denoising, deblurring, and dejpeging process for your images to improve image clarity, sharpness, and fidelity; and provide more details.

Unlike other AI image enhancers, you don’t need to spend much time downloading AI models or adjusting parameters, Aiarty Image Enhancer handles everything for you effortlessly. The built-in AI algorithms analyze the original image, increase image resolution, reduce noise and blur, and intelligently fill in missing details, creating a more natural and sharper high-resolution image with more details.

Aiarty Image Enhancer provides three AI models for you to enhance image quality while converting image to high resolution.

• More-detail GAN model can generate intricate details to improve clarity and sharpness. Also, it does well in removing noise, blur, and pixelation issues. This AI model can effectively enhance image types that emphasize details and sharpness, like animal fur, bird feathers, eyelashes, eyebrows, hair, wrinkles, freckles, pores, texture on cloth, the outline of a distant building, wood grain, and more.
• Smooth Diff is capable of creating smoother, clearer, and brighter images while maintaining the original features of images. It is tailor-made for enhancing image categories with fewer intricate details, such as 2D animations, cartoons, glass surfaces, smooth textures, logos, and line drawings.
• Real-Photo is capable of enhancing and upscaling photorealistic photos; and restoring old photos from yesteryear. Especially, it excels in enhancing the quality of high-resolution real photos that contain noise or imperfections

How to convert low resolution images to high resolution with Aiarty?

Step 1. Free download Aiarty Image Enhancer, install, and launch it.

• Please make sure your computer has met the minimum system requirements to install Aiarty Image Enhancer.
• The trial version of Aiarty Image Enhancer comes with some limitations. You are suggested to upgrade to the full version to unlock all features.

Step 2. Drag and drop one single image or multiple images to Aiarty Image Enhancer.

Step 3. After analyzing, choose an AI model in the right panel.

• More-detail GAN model is better for significant upscaling while prioritizing details and clarity.
• Smooth Diff model is better for creating smoother, clearer, and brighter images.
• Real-Photo model is better for upscaling photorealistic photos and restoring old photos.

Step 4. Choose a resolution or an upscale scale.

• Choose x1 to enhance image quality while eliminating noise, blur, pixelation, etc. artifacts.
• Choose from x2, x4, or x8 to convert images into high resolution up to 32K (on Windows) or 16K (on Mac).
• Choose from 1K, 2K, 4K, or 8K to increase image resolution to 1K, 2K, 4K, or 8K.
• Choose Custom Resolution to customize the image resolution by entering a specific value for width or height.

Step 5. Optional customization.

• Choose CPU or GPU if it is more powerful to process the image enhancement process.
• You can enable "2-Pass processing" which can involve an extra round of x1 image processing to get an image with richer details.
• If your image is AI-generated, you can see the image prompt by clicking on the "View" button. You can also keep the prompt after upscaling.
• If needed, you can add text to your images by clicking on the "Add Text" button.

Step 6. Specify the export settings.

• Choose an output format and quality level. You are suggested to use the default settings.
• Click on the "Browse" button to choose a folder to save the upscaled images.

Step 7. When everything is OK, hit the "RUN" button to start converting images to high resolution with Aiarty Image Enhancer.

Method 2. Convert Images to High Resolution with Adobe Photoshop

Adobe Photoshop is an iconic and worldwide-known photo editing software that has processed billions of images. You can also use it to convert photos and images from low resolution to high resolution. The ways Adobe Photoshop provides are Resampling and Super Resolution. You can get some basic information before using them to increase image resolution.

Super Resolution is an AI-powered function in Photoshop to increase image resolution while keeping image quality in good shape. Adobe has trained the Super Resolution feature with millions of real-world pictures. With a simple click, you can instantly quadruple the pixel count in any photograph. Through the help of AI power and machine learning techs, Photoshop can choose the best-looking pixels for the context of every image and make the image crisp-looking and a framed print to put up on your wall.

The other way is called Resampling. When converting images to high resolution, you need upsampling to increase the number of pixels in an image and increase image resolution. Also, the resampling feature allows for achieving greater control over the images with selective sharpening techniques. Following the upscaling process, it selectively sharpens particular parts of the image to enrich its details without introducing any unwanted artifacts.

How to increase image resolution with Photoshop’s Super Resolution?

Step 1. Open a raw file first. The raw files would open up automatically in the Adobe Camera Raw tool.

Step 2. Right-click the shot and choose Enhance.

An Enhanced Preview dialogue box will appear, with a few options for managing the procedure.

Step 3. Check the Super Resolution checkbox, and pan around the preview image to see the expected results. Then, click the magnifying glass icon to zoom out, and then click back on the patch you want to investigate.

Step 4. Click the Enhance option.

Step 5. After that, zoom in close enough to fine-tune aspects like sharpness, texture, and noise removal by using scales on the tool’s right edge.

Notice: If you want to use Super Resolution with JPEG, HEIC, or TIFF files, first you need to set Photoshop to open those file formats in Adobe Camera Raw by default. You can do as follows:

1. Browse the File Handling section and select Camera Raw Preferences from the menu.
2. When a dialog box appears, select the File Handling area.
3. Change the JPEG/HEIC option to "Automatically open all supported" images, then repeat the process for TIFF files if required.

How to increase image resolution with Photoshop’s Resampling?

Step 1. First, open the image you want to increase resolution in Photoshop.

Step 2. Go to the "Image" menu and select "Image Size".

Step 3. When the "Image Size" dialog box appears, check the "Resample Image" option. Then, select an interpolation method from the drop-down menu. "Bicubic Sharper" or "Bicubic Smoother" is recommended.

Step 4. After that, enter your desired width and height for your image. Then, click "OK" to confirm your changes.
