Cloud Photos Optimization

Suppose your web tool doesn't compress photos automatically, then you can use https://tinypng.com/, but this is limited to 20 images of 5 MB max. each.

Whatever is described below, the smartest compression remains !TinyPNG.

TOOL	ORIGINAL SIZE	DURATION	SIZE AFTERWARDS
PNGoo	705 MB		814 MB... (what the f***!)
Caesium	705 MB	quick	163 MB
JPEG Compressor by pikazho	705 MB	quick	155 MB
MassImageCompressor 80% quality, 70% size	705 MB	quick, 39 sec.	55 MB
