I was wondering how to remove an ICC profile from a CMYK jpeg? It seems to be causing problems and inverts the colours of the photo when we upload it to our website. It needs to be CMYK though for printing purposes. Thanks!
First of all, never upload images to a web site in CMYK mode. It might be exactly what you need for the print job, however it's not what you need for the web. So first, we'll make a copy of your CMYK file and convert it to RGB mode, then we'll remove any unnecessary ICC profiles.
Open the CMYK image.
Choose Image > Duplicate...
The Duplicate dialog box appears.
Name the file and click OK.
A duplicate file is created.
You can close the original image now and concentrate on the duplicate.
Choose Image > Mode > RGB Color
The mode is converted to a web-friendly color mode.
Next, we'll remove any ICC profiles.
Choose Edit > Assign Profile
The Assign Profile dialog box appears.
Select the Don't Color Manage This Document option.
Your image will display on the web more accurately as an RGB file and it's file size will be smaller because the ICC profile has been removed.
