Hey, I want to know is there is anyway we can convert selected object in to grayscale. Not all the artwork but only selected picture or object into grayscale?
Edit > Edit Colors > Convert to Greyscale.
Images need to be embedded.
Thanks for the answer that’s the thing which I was looking for.
Good to hear that helped.
Or you can apply Effect > Rasterize and choose greyscale.
The advantage is that it is an effect and can be changed or turned off.
The disadvantage is that your vectors will behave like an image.
If you wish to retain the original coloured object/image, remember to keep the original as backup and work with a copy (usually recommended before destroying artwork).
Or there is a silly way to work reversibly with the original whether vector object or raster image, and the latter can be linked to keep the file size down.
And any effect way, as the one suggested by Ton, is always reversible.
