About PixelTuneup

PixelTuneup's sole focus is to provide a fast, free, and easy-to-use AI image upscaling tool. Our goal is to make professional-quality image enhancement accessible to everyone — designers, photographers, content creators, and everyday users alike — with no software to install, no account required, and no cost.

Our upscaler uses state-of-the-art AI to enlarge images up to 8× their original resolution while reconstructing realistic detail, reducing noise, and sharpening edges. Unlike basic resizing tools that simply stretch pixels, our AI model has been trained on millions of images to understand what real detail should look like at higher resolutions.

We believe the internet should be a source of free, useful tools. All of our services are completely free to use, with no registration required. We are committed to user privacy — images are processed securely and deleted immediately after upscaling is complete.

If you notice any issues or have suggestions for improvement, we'd love to hear from you at hello@pixeltuneup.com.
