How to convert a 16-bit linear gamma image to an 8-bit gamma 2.2 image with good results?

I have tried using krita to convert, but the effect is not good.

Is there any free software that can achieve this?

Hello @Eranthis_stellata!

Maybe it would be possible with XnConvert, if you have the necessary ICC profile files available. How the quality of the ICC profile conversion is, I can’t tell you unfortunately, only that I was satisfied so far for my purposes with it.

This software offers many possibilities for the conversion, in the screenshot you see the window in which you pass the profile files to the software.
This freeware is available for Linux, Windows and Mac, for Linux there are “DEB Packages” as well as “TGZ Archives”.

你好 @Eranthis_stellata!

XnConvert也许可以,只要你有必要的ICC配置文件可用。不幸的是,我不能告诉你ICC档案转换的质量如何,只能说到目前为止,我对它的用途感到满意。

这个软件提供了许多转换的可能性,在截图中,你可以看到将档案文件传输到软件的窗口。
这个免费软件可用于Linux、Windows和Mac,对于Linux有 "DEB包 "以及 “TGZ档案”。
