You can use Picture Converter 4 :)

See this example : https://imgur.com/a/aYRyNF0

This version is not released yet but contact me if you want to try it out :)

Yes, but if it is supposed to be lossless someones up for a disappointment. ;)

@CommFor: Why does it have to be Koala format?

I want to make BBT files out of C64 games - it's a BackBit format allowing slideshow up to 10 Koala pictures, 1 SID tune and text infos for each game (game is also included in BBT file).

I guess it is for some kind of start menu for this product https://www.backbit.io/

I tried Mufflon, but doesn't fit my purpose.

Picture Converter 4 is really great tool for pros, but Pixcen do the part of the job I need easier.

It's not a spam, I just explain reasons why I need it, so people here will understand better it's not just to play with it to convert few game screenshots.

Thanks to your help and my digging of C64 tools on this great site I came to conclusion best way to achieve my goal is:

1. Using WinVICE (Pepto PAL palette) and take a game screenshot (Alt+Shift+R) saving it as BMP picture
2. Get rid of borders in BMP picture using Canvas size option to have it in 320x200 resolution in Timanthes
(yes, I know this process can be automatized for bunch of files using some PC tools, still in progress to get there)
3. Load this BMP in Pixcen and save it as Multicolour in Koala format

Static screens look perfect this way, in-game screenshots are pretty decent, even with games like Turrican II or Mayhem.
Game screenshots can't be perfect in Koala format because of restrictions it has, thanks to all for explanations.

Is there a way to process bunch of BMP files to be automatically converted to KLA multicolour format?
Now I need to do to it manually one by one using Pixcen.

Hm, there probably is a tool that can do bmp to kla via commandline, would be easy to write a batch file then.

Edit: Did some searching on here and the web and could not find any commandline conversion tool, which I have to say I find rather weird. Maybe it is out there, but I could not find it.
