PNG Dateien seit Update auf Photoshop CC 2018 viel zu groß

Hallo Zusammen,

seit dem neusten Update habe ich das Problem, dass die gespeicherten PNG Dateien fast 10x so groß sind wie mit der alten Version (Freisteller als PNG vorher zwischen 3-7mb, jetzt zwischen 40-70mb)

Bei den PNG-Format-Optionen (Speichern unter...) nutze ich immer "Kleinste Dateigröße (langsamstes Speichern)".

Ich habe auch schon die anderen zwei Optionen benutzt (Große Dateigröße und mittlere Dateigröße). Bei allen 3 erhalte ich die gleiche Dateigröße.

Kennt dieses Problem noch jemand oder weiß jemand wo das Problem liegen könnte?

Vielen Dank und Grüße,

Miriam

Could be the metadata in the file.

Have you tried File>Export>Export As or File>Export>Save for Web (Legacy)?

Under Metadata set it to None and see if there is a huge difference in the saved file size.

Also, png supports 16 bits/channel, so that could explain the doubled file size versus an 8 bits/channel png.

Hi Jeff,

that is the solution.

I saved my PNG files always as "save as"!

The size of the files was generally 5-7mb.

Now, with the new Update, they are 50-70mb.

But with File-Export-Export as, they are "normally" 5-7mb again.

Thanks for your help
