Yes, you can certainly post-edit your QR codes yourself using a graphic program. However, it's important to ensure your QR code remains scannable after editing. Be cautious not to alter the essential elements of the QR code, such as the arrangement of the black and white modules, as any significant changes could render the QR code unscannable. Always test the edited QR code to confirm its functionality before using it in any materials or promotions.
