Plugin Doesnt Store Color Profile
-
Before leaving a review, id like you to reply for a solution.
I installed the plugin and uploaded some images to a local test. All worked fine, the images were converted to webP.
However the images loose their color profile, and as im looking to use this for a photography site, this simply isn’t usable as color accuracy is vital.
I then downloaded the webp plugin for PS https://github.com/webmproject/WebPShop/releases to run some tests.
Taking the same original jpeg image, saved as 12 quality (best) that i ran though your plugin, i then saved it as 80% quality (same as your recommended setting in your plugin), both with “Keep Color Profile” on and off:
– Original Jpeg: 704KB
– Your Plugin conversion: 86.7KB
– PS WebP at 80% with Color Profile OFF: 79.8KB
– PS WebP at 80% with Color Profile ON: 80.4KBAs you can see the PS versions, both with and without color, are smaller than yours, but im not to phased about that, as my main point here is that even with the Color Profile on, the PS version is able to match the size of both the OFF and your plugin, so there is no negligible hit in file size.
in other words, why no add it as an option in your plugin and there is no downside and increases color accuracy of images?
Then just for fun, I see you also support AVIF in your pro version, so also downloaded to PS plugin for that https://github.com/0xC0000054/avif-format/releases
– PS AVIF at 80% with Color Profile ON: 81.7KB
The compression quality was better (sharper) than WebP, while keeping the same file size, so it is definitely a better algorithm. But again, I assume that you too don’t support color profile in you plugin, so again this makes it useless for anyone who cares about color accuracy in their websites images.
Conclusion
Are you able to add Color profiles to both compression formats?
Id really like to use your plugin, as it more automated and thus convenient than individually saving webp or AFVI files through PS, but without a color profile, it simply isnt usable.
Thanks

Ok i think i found the problem.
My images are saved in Adobe RGB, as this is what i have set in Adobe RAW, as its a wider color profile than standardRGB when editing photos.
However, WP doesnt know what to do with Adobe RGB, as its limited to sRGB only. Although, it seems that browsers do seem to know what to do with Adobe RGB.
That is why all the images you linked above, looked as thought they work, because when i click on them, they open in my browser and not through WP.
If you put the images into WP via a post, they ICC will be incorrect again, as WP becomes confused, even though the data is technically within the image.
However once i re-saved the original JPEG as sRGB through PS, then ran them through your plugin to WebP, and viewed them through WP as a post, it kept the correct sRGB profile and looked the same as the JPEG.
This post gave me the idea https://www.ads-software.com/support/topic/disregards-icc-color-profile/
So in conclusion, id think that its important to mention to keep images in sRGB in your installation or FAQ sections for future users.
