Why Convert GPL to ACO?
Going the other way — from GIMP, Inkscape, or Krita into Photoshop — means converting the GPL palette to ACO, the Photoshop Color Swatch format. This tool does that in one step, in your browser.
Every color in the GPL file becomes a swatch in the ACO file, which loads directly into Photoshop’s Swatches panel.
The output uses ACO version 1 for maximum compatibility. One honest caveat: version 1 stores colors only, so swatch names from the GPL file are not carried into Photoshop.

Frequently Asked Questions
How do I load the ACO file into Photoshop?
Open the Swatches panel, click the panel menu → Import Swatches (or Load Swatches in older versions), and select the .aco file.
Are color names preserved?
No — the ACO v1 format the converter produces stores color values only, so swatches arrive unnamed in Photoshop. Colors themselves are preserved exactly.
Is there a limit on palette size?
No practical limit — every color line in the GPL file becomes a swatch.
