How to increase resolution of an image on Windows 11/10?
I have several low-resolution images that I need to make larger and clearer for a project. What's the best way to upscale images on Windows? I'm aware that simply resizing an image in Paint or Photos makes it blurry or pixelated.
Are there any free or built-in Windows tools that can increase resolution of an image on Windows 11/10 while preserving quality? I've heard about AI-based tools with resampling, or online options, but I'd prefer something offline and privacy-friendly if possible.
What do you actually recommend for Windows 11 in 2026? Thanks.

To increase resolution of an image in Windows 11. Given that you are training to be an IT consultant, I would argue that learning to run a single command-line tool is a valuable skill. But if you truly want no Terminal at all, Real-ESRGAN-GUI is your path.

What makes Real-ESRGAN different from other upscalers is how it was trained. Most older upscalers were trained on clean, perfect "lab" images, so they fall apart when given real-world photos—think old screenshots, compressed WhatsApp images, or grainy product photos. Real-ESRGAN was trained on real-world degradation patterns, which means it handles those messy, imperfect source images much better.
Unlike simple resizing that just stretches pixels, Real-ESRGAN actually predicts and reconstructs missing image details to increase resolution of an image in Windows 11 without turning it into a blurry, pixelated mess.
In March 2026 tests on a Windows 11 laptop, Real-ESRGAN produced solid, steady results on old UI screenshots, slide graphics, product labels, packaging, and logos without tiny text . It is not a "wow" tool that creates magic from nothing—it is a dependable, professional-grade tool that does one job well.
The NCNN version is a pre-built, portable executable that requires no Python installation and has no dependencies. You simply download a zip file, extract it, and run it from the command line.
If you want to increase resolution of an image in Windows 11 using Real-ESRGAN and you absolutely refuse to use the Terminal, your only option is Real-ESRGAN-GUI. It is free, it is graphical, and it works for most users . However, it is unofficial, and some users report stability issues.

Increasing the resolution of an image on Windows 11 or 10 can be done in several ways, depending on the result you want. You can use built-in tools for simple resizing, try Microsoft's new AI feature for smart enhancement, or use third-party software for more advanced control.
The simplest way to change an image's size is with the apps already on your computer. It's important to note that these methods do not add new details; they simply stretch the existing pixels. This can make the image look blurry or pixelated if you enlarge it too much.
Increase Image Solution Using Microsoft Photos App:
- Right-click on your image file and select Open with > Photos.
- Click the "..." (See more) button in the top-right corner and select Resize image.
- Choose one of the preset sizes (e.g., Small, Medium) or click "Define custom dimensions" to enter your own.
- Choose the save options and save your new image.
Increase Image solution Using Microsoft Paint:
- Right-click on your image file and select Open with > Paint.
- On the toolbar, click the Resize button.
- You can resize by Percentage or Pixels. Check the "Maintain aspect ratio" box to avoid distorting the image.
- Enter your new values and click OK. Save the file.

Waifu2x is a free, open-source AI upscaling tool, and it is a reliable solution for how to increase resolution of image, especially optimized for anime, illustrations, and pixel art.
It allows you to upscale images up to 4x while reducing noise, but it works best on non-photorealistic content like cartoons and line art.
First, download the software from the official repository and open it, then drag and drop the image into the main window.
Select your desired scale (2x is recommended for most use cases), choose a denoise level (leave it at 1 if you’re upscaling photos), and click Start to begin the process. Wait for the upscaling to finish, then save your high-resolution output files.
This method is ideal for users who want to upscale anime or artwork, but it is not the best choice for realistic photos compared to other AI models.
