About PixelBoost

AI-powered upscaling · Free · Private

What is PixelBoost?

PixelBoost is a free image enhancement tool that uses artificial intelligence to increase the resolution and visual quality of your photos, illustrations, and graphics. It runs entirely in your browser — no account, no installation, no cloud processing required.

The result is a high-resolution PNG you can download immediately, with significantly more detail than traditional upscaling methods produce.

Who is it for?

PixelBoost is built for anyone who needs to enlarge images without sacrificing quality — photographers preparing prints, designers working with legacy assets, gamers restoring old character art, or anyone dealing with low-resolution source material.

It works equally well on photographs, digital illustrations, scanned documents, and screenshots.

Privacy first

Your images are processed locally on your own device. Nothing is uploaded to any server. PixelBoost has no backend, no storage, and no access to your files — what happens in your browser stays in your browser.

Zero uploads. The AI runs entirely inside your browser tab. Not a single pixel leaves your device during processing.

Output quality

PixelBoost automatically scales your input so the final result targets near-2K resolution — around 2048px on the longest side. This keeps processing fast while delivering output that is sharp at full screen, suitable for A4 print, and ready for most professional use cases.

When your browser and hardware support it, GPU acceleration is enabled automatically — reducing processing time from minutes to seconds.

Free, always

There is no premium tier, no watermark, no compressed export, and no usage limit. PixelBoost is free to use for personal and commercial projects alike. The tool is supported by non-intrusive display advertising that keeps it free for everyone.
