How to Convert Low-Resolution Images to High Resolution with AI

By Joakim Kling | Last Update:
Listed in AI Image Tips

With the proliferation of high-resolution displays and the need for crisp, detailed images in everything from documents to websites, converting low-resolution images to high resolution has become increasingly important. But is it actually possible to take a low-quality, pixelated image and turn it into a sharp, high-res version? Thanks to AI, the answer is yes. This article explains what defines low and high resolution images, whether AI can effectively upscale resolution, and how to convert low resolution photos to high resolution using AI-powered tools like VideoProc Converter AI.

Convert Image to High Resolution

Understand Low-Resolution and High-Resolution Images

In the world of digital imagery, the resolution is essentially the sum of all the pixels that make up an image, which you calculate by multiplying the width by the height in pixels. For example, a 640 x 480 image has 307,200 total pixels (640 x 480), while a 3840 x 2160 image has 8,294,400 pixels.

Higher resolution equals more pixels and intricate details, making images ideal for high-quality prints, wallpapers, and fine art. High-resolution also matches high-definition screens, so 4K photos look sharp on 4K monitors while low 480P images look fuzzy and pixelated. Low resolution is okay for smartphones but pixelation is pronounced on larger displays, making low-res unsuitable for professional use.

Image Type Definition Example Usage

Low-Resolution

For printing: ≤72 DPI
For digital: ≤1 million pixels

1024P x 768P
(0.8 million pixels)

For small screens; Loses quality when enlarged

High-Resolution

For printing: ≥300 DPI
For digital: ≥ 2 million pixels
Read: How to Increase the DPI

1920P x 1080P
(2 million+ pixels)

Give more detail. Can be enlarged more before losing quality

Can You Convert a Low-Resolution Image to High Resolution

In short answer: Yes, thanks to advancements in technology, you can make low-resolution pictures high resolution using AI-based upscaling techniques.

Traditional upscaling methods like bilinear, bicubic, and Lanczos interpolation primarily increase the size of an image without enhancing its quality. By estimating values based on surrounding pixels, these methods generate additional pixels via interpolation, resulting in a larger but potentially blurry or pixelated image. The original detail present in high-resolution images isn't truly added or captured through this process.

AI-based upscaling method, on the other hand, can do more than increase the image size. It can add new details and remove quality issues like choppy edges and noise. For instance, Super Resolution, one of the most advanced AI image upscaling techniques used by VideoProc Converter AI HOT, learns from huge sets of low and high-resolution images. By studying patterns and textures, it figures out what the new pixels in the upscaled image should look like. This allows it to not only make the image larger but also significantly improve its clarity and realism. In other words, the AI fills in the gaps, making the image bigger and better, and adding missing details for sharper and more realistic results.

How to Convert Low-Resolution Images to High-Resolution

A variety of high resolution image converters can help convert resolution images to high resolution. Keep reading to learn how to convert low pixel to high pixel in 5 easy ways.

1. Use VideoProc Converter AI

Rating: by Capterra

Overview: With VideoProc Converter AI, low resolution images can be upscaled up to 400% of original size. For example, a 600x600 pixel image could be upscaled to up to 2400x2400 pixels

VideoProc Converter AI can convert images from low resolution such as 480P and 560P to 1080P, 2K, 4K, and even 8K resolution. Thanks to the application of the advanced Super Resolution technology, it can recognize intricate patterns and features in the original image, then intelligently predict what should be added to the new pixels, resulting in a remarkable up to 400% increase in resolution while preserving the original details without introducing any unwanted artifacts. Better yet, it comes with different models to convert low-resolution real-life images and animes more efficiently and get the best possible result.

Step 3. Choose the desired scale - 2x, 3x, or 4x - to make low resolution pictures high resolution. For example, if your low-resolution picture is 512x512, selecting 2x will transform it into 1024x1024, 3x into 1526x1526, and 4x into 2048x2048. You can apply the same settings to multiple images or right-click on the current image in the list.

Choose High Resolution Settings

Step 4. Select the output image format, and then click RUN to export the high-resolution image. You can also repeat the upscaling process multiple times before reaching the maximum output of 8K, which is nearly 8,000 pixels in width.

Price: $29.99/year. It offers intelligent AI-driven tools for improving videos and images, as well as features for editing, compressing, downloading, and recording videos

Supported formats: PNG, JPG, JPEG, WebP, PBM, XBM, PGM, PPM, XPM, GIF, and more

Maximum image dimensions: 4000px on each side

2. Use Fotor

Rating: by Macworld

Overview: With Fotor, low resolution images can be upscaled up to 200% of original size. For example, a 600x600 pixel image could be upscaled to up to 1200x1200 pixels

Fotor has been available in the market for over a decade, establishing itself as a versatile photo editing tool accessible both online and as installed software. Beyond basic photo editing functions like cropping and resizing, Fotor sets itself apart with a number of AI-powered features that simplify complex edits with a single click. The background remover, for instance, lets you remove the background from your photo effortlessly within seconds. It has a powerful AI Photo Enhance. Notably, it uses artificial intelligence to instantly improve image quality and convert low resolution images to high resolution without making your images too sharp. However, this tool has limitations for users wanting to make very low resolution pictures high resolution, as it only supports up to 2X resolution upscaling. Let's say, if your original low-pixel image is 480 x 480P, Fotor can only upscale it to 960 x 960, which is not considered high resolution.

Step 1. Navigate yourself to the Photo Enhancer tool of Fotor.

Step 2. Click Enhance Photo Now and select the source low-resolution images for loading to Fotor. It now automatically make low-resolution pictures high resolution.

Step 3. Hit Apply to start converting your low quality image to high quality. Hit Done to download the high-resolution version of your images on the computer.
