Import PNG Palette is a lightweight Blender add-on from Ruuubick that reads a PNG image and turns it into a color palette. Community add-ons already handle several palette formats, but not PNG, and this add-on was built to fill that gap.
You import from File → Import → Import PNG as Palette and pick your .png file, for example one downloaded from Lospec. Options let you cap the total with Max Colors, merge near-identical shades using an adjustable Color Similarity Tolerance, and skip transparent pixels and blank regions. The finished palette lands under Properties → Tool Settings → Palette, named after the image file. It works with Lospec's horizontal, vertical, and grid exports at 1x, 8x, and 32x resolution.
Version 1.0.2 is compatible with Blender 4.2 LTS and newer and is released under the GNU General Public License v3.0 or later. A few limits apply: very large or photographic PNGs may be slow to process, colors past the Max Colors limit are skipped, and a duplicate palette name overwrites the existing one unless renamed manually.
