Is this the same as printing in black and white?

The result is the same on the page, but this changes the file itself — so it stays greyscale wherever it is opened, rather than relying on a print setting.

Can I get the colour back afterwards?

No. Colour is removed from the output, so keep your original if you will need it again.

Print shops charge by the colour page, and a deck with one tinted logo per slide counts as colour throughout. Converting to greyscale first removes the surcharge and usually shrinks the file too.

Questions people ask

Colour information is discarded and pages are re-encoded, so image-heavy documents often shrink substantially. Text-only files may not change much.
