unexplained difference Photoshop-Gimp PNG filesize
#1
I worked with Photoshop for several years and use the "Save for web" function daily.
I start to become somewhat familair with Gimp but I have one big issue.

As far as I know, there is no (standard) function "save for web" in Gimp.
So, I do it step by step.

As an example I exported a image from Lightroom in PSD format and open it in Gimp.
It is a image without transparency.
I use Gimp 2.10

First I resize / scale the image to acceptable size like 800 px wide, like I do in Photoshop, with cubic interpolation (I use bicubic in PS)
Then I use the export function, change the extension to .png (every checkbox is empty, like interlacing, save background color).
I have selected 8bpc RGB, compression level 9 and hit Export.
The .png file that is created is almost 3 times bigger then when I use the "save for web" function in PS.

- Flatten image is not the solution, there is no transparency.
- I assume I use already maximum compression for png.
- The number of pixels width-heigt are exactly the same in PS as in Gimp.

What steps do I forget to have a file size comparable to PS?
