Digital colour pics to black & white

[coco h]

No idea if possible - but if you have bog standard digital camera which takes only in colour - can you somehow using a website perhaps get the pics printed in black & white or sepia?

Every photo editing app will do Colour to B&W conversion.
Its fairly easy to do (though harder to do well).
