Save for Web: Checking "Convert to sRGB" alone makes image untagged?

[Doe Johns]

I just found an old thread where gener7, Adobe Community Professional, wrote:

Now here's the funny part. If I have an untagged (no profile assigned) picture in Photoshop and use SFW:

Checking both embed and convert will tag it sRGB. Unchecking "embed profile" and keeping "convert to sRGB" checked will leave the document with no profile or untagged.

I can confirm it with CS6 on Windows. If you open an image with Adobe RGB profile assigned and then re-save it for Web as JPEG with only the "Convert to sRGB" check box, that resulting JPEG will be untagged (Photoshop will refer to it as "Untagged RGB").

Is it a bug (maybe already fixed since then) or a feature? Why it happens?

So, I have read the post twice and don't see the problem. If you don't embed the ICC profile, why would there be any surprise that there is no ICC profile when it was explicitly left unchecked? What am I missing?

Yeah, it seems you are right. Duh.

Convert changes the numbers. Embed profile embeds the profile (not to rub it in 😉 )

"If you open an image with Adobe RGB profile assigned and then re-save it for Web as JPEG with only the "Convert to sRGB" check box, that resulting JPEG will be untagged (Photoshop will refer to it as "Untagged RGB")."

Of course, that’s expected behaviour. If you don't check "embed profile" then no profile is embedded.

Better to chack it by default as a matter of course. 

I hope this helps
