How to enhance and enlarge blurry photos using AI

Upscayl is a free, open-source desktop application that solves a massive problem: turning low-resolution, pixelated images into high-quality, sharp photos. By using advanced AI models locally on your machine, it saves you from paying expensive subscriptions for web-based enhancers. Follow these steps to upscale your images:

  1. Import Your Image
    Open the Upscayl application and click Select Image (or simply drag and drop your file into the window). If you have multiple images to process, toggle the Batch Upscayl switch to upload an entire folder.
  2. Choose an AI Model
    Select the upscaling model that best fits your image type. For standard pictures, use General Photo (Real-ESRGAN or Remacri). If you are enhancing 2D drawings, select the Digital Art or Anime-specific models to prevent weird, unwanted textures.
  3. Set the Output Folder
    Click Set Output Folder to choose exactly where the newly enhanced, high-resolution image will be saved on your computer.
  4. Click Upscayl
    Hit the Upscayl button! The software will utilize your computer's graphics card to generate the new pixels. Once finished, a side-by-side slider will appear so you can easily compare the blurry original to the sharp result.
Pro Tip: Need an image to be massive for a poster print? Check the Double Upscayl box in step 2. This will run the AI process twice, enlarging your original image by up to 16x its original size!

Frequently Asked Questions

Yes. Because the desktop version of Upscayl runs AI processing locally on your machine, it requires a Vulkan-compatible GPU to work efficiently. If you are running it on an older machine with only a basic CPU, the process will either fail or take a very long time. For older machines, you can opt for their paid Upscayl Cloud service.

AI upscaling works by "guessing" missing pixels based on its training data. Sometimes, an AI model will over-sharpen an image or hallucinate details that shouldn't be there, especially on small faces or highly compressed, noisy backgrounds. To fix this, try processing the image again using a different model from the dropdown list (like switching from Real-ESRGAN to Remacri or Ultramix Balanced).

Yes, the desktop application is completely free and open-source. You can download it for Windows, Mac, or Linux and use it forever without paying a dime. They do offer an optional, premium subscription called "Upscayl Cloud" which processes images on their high-speed servers, bypassing the need for you to own an expensive graphics card.

Yes. Advanced users can easily add custom models to the software. You simply need to create a folder on your computer, place your custom NCNN models (in .bin and .param format) inside, and then link that folder to Upscayl via the Settings tab.
