Brilliant tool, I planned to add this to the "other software" forum as a thank you for lots of interesting links (today I read something about JPEG ELA forensics), but obviously you know TweakPNG already. I could post two scripts for the TweakPNG "tools" feature, combining PNGwolf+TruePNG (if anybody uses that, maybe Dos386.)

Good to know, as it happens I have that, together with an "sRGB intent saturation" default. Kudos.

still results in an “error writing the file”.
