Upscale photos to print-ready resolution

Turn a 72 DPI screenshot into a 300 DPI print file.

Printers need roughly 300 DPI at the physical print size, which often means upscaling your source photo 2-4×. Quick Fix does it without the pixelated or plastic look of traditional upscalers.

Upscale 2× or 4× with the Swin2SR open-source model

Upscale factor

Input is capped at 4 megapixels on CPU to keep runtime reasonable. Output will be 2× the (possibly downscaled) input.

Useful since 4× can take a few minutes on CPU.

Why Quick Fix

2× and 4× factors cover most print use cases
Output is PNG by default — drop into Illustrator or InDesign
Natural-looking detail instead of sharpening artifacts

Frequently asked

What DPI will the output be?

DPI is metadata — the actual pixel count is what matters. Quick Fix gives you 2× or 4× the pixel dimensions. Your layout software can then assign whatever DPI suits the physical size.
