You can order black and white prints, but unfortunately it's not possible to convert your coloured photos to black and white via our website when ordering prints.
We'd suggest that you edit your photos using a photo editing tool (BeFunky or Pixlr for example) before uploading them to your Photobox account and ordering your prints.
*You can order black and white prints via our App, where you can use filters (we proposed a range of filters including black and white filter).
