When upscaling a PNG into JPG for less memory consumption, it results in the image losing its color, something that doesn't happens in other web based image upscalers.
To Reproduce
Select a PNG
select "Save as: JPG"
Run upscayl
Image results in color loss
Upscayl Version (or commit hash)
2.11.5
Platform
Windows
OS Version
10
GPU Name
NVIDIA GeForce RTX 2060
Expected Behavior
Shouldn't the image keep its color after the upscale?
Hello, @Alvaro-2998! I'm here to help you with any bugs, questions, or contributions. Let's tackle this issue together!
I found a similar closed issue regarding color profile preservation during image conversion in Upscayl, but no solution was found in the comments [1].
Currently, there is no specific information available in the Upscayl repository about how color profiles are managed during the conversion from PNG to JPG, or any settings that might affect color management during image processing. The Real-ESRGAN library, which Upscayl uses for image conversions, also does not have documented issues or limitations regarding color profile handling that I could find.
If the color loss issue persists, you might want to explore alternative methods or tools for converting images while preserving color profiles, or consider using a different image format that better supports color profiles.
