# Options
ICC color profiles typically describe the color input or output device of an image. For digital images distributed online, sRGB is mostly used, while CMYK is the standard for printers. Color profiles are set when exporting images from the camera or the graphics editor. They sometimes add unnecessary weight to your image files and slow down loading times on the web. Scaleflex DMO (Optimization) converts by default the ICC color profile into sRGB on-the-fly, which is the most optimal ICC profile for the web. You can change the default behavior. We can automatically convert your profiles to a sRGB profile in order to have a minimum loss of quality and a much lighter filesize. You might notice a small difference in the colors but usually it's not noticeable.
By default, if the origin image has an embedded ICC profile, the image is converted to the sRGB colour space and the ICC profile is removed from the compressed image. We can automatically convert your profiles to a sRGB profile in order to have a minimum loss of quality and a much lighter file size.\

You may choose not to use the above feature by enabling the checkbox **"Keep origin image ICC profile".** You can also specify that the ICC profile will only be converted to sRGB if it is larger than XX KBs.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.scaleflex.com/dynamic-media-optimization-dmo/settings/images/options.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
