How the Processing Engine Works
Because standard PNG compression is lossless, file size directly correlates with pixel dimensions and color palette depth. Our tool calculates the exact dimension scale factor necessary to bring the PNG payload under 100KB without dropping transparency.
Balancing Quality, Dimensions & Target Size
If a large, photographic PNG cannot reach 100KB without drastic dimension scaling, converting to WebP or JPG is recommended. Our tool provides a clear notice so you can make the right decision for your specific graphic.
