### 3/5 — prima für umsonst – aber …

*2020-11-13*

Dafür, dass die App nix kostet, ist die verrichtete Kompression akzeptabel: bei gleicher Qualität in meinen Tests 44% des JPG-Originals (636 KiB). Allerdings ist Googles ImageOptim ebenfalls gratis und das Resultat ist bei gleicher Bildqualität nur 20% so groß wie die Ausgangsdatei: 282 KiB zu 1,3 MiB. Eine gleich große Datei ist in der Qualität viel schlechter.
