pngquant --quality=65-80 image.png -o compressed.png --force

sounds like a search engine riddle. After all, why would you convert a PNG to a PNG? Isn't that like re-filling a glass of water that is already full?

Standard "PNG to PNG" conversion (saving the same file again) does not improve quality. However, using specific tools for quality changing can produce a "better" version of the same image: Quality Adjusters : Tools like Online PNG Tools

The answer is not a "converter." The answer is an . By applying Zopfli compression, stripping metadata, reducing color palettes, and validating chunk structures, you can take any source PNG and output a target PNG that is:

Removing unnecessary chunks typically reduces file size by 5-15% with zero visual impact.

Result: 1.1MB -> 350KB (Indistinguishable visual change)
