You can test the exact color mapping on one sprite before buying the batch edition.
1. Open the free browser demo and choose Try a sample sprite, or Choose one PNG for your own permitted artwork.
2. Set your replacement RGB colors. Leave a replacement blank to keep that color. Similar shades need separate mappings.
3. Check the preview and unmapped colors, then download the PNG. Save the mapping JSON if you want to reuse it.

The offline batch ZIP remains $5 USD minimum, one-time. It adds folder/ZIP import, up to eight named variants, and a ZIP with the original paths inside each variant folder. Dimensions and alpha are preserved; PNG metadata is omitted. Intended for current desktop browsers; format and workload limits are on the page.

If you try one of your own sprites, did it export the variant you expected?
