Why convert PDFs to black and white?
Imagine you need to securely send an email with a PDF, but when you hit send, you’re warned the file size is too big. What’s the holdup when you’re just trying to send one or two PDF files? As it turns out, a full colour PDF file takes up a lot more space than a purely black-and-white one. If you convert a color PDF to black and white, it can significantly reduce the file size, making the PDF much easier to send.
You may also need to change a PDF to black and white for legal compliance reasons, as some legal documents can only be submitted in monochrome. Converting a PDF to grayscale can help with printing costs, too, with monochrome printing often being much cheaper than colour printing. An online file converter makes it simple to convert your PDF to black and white, while maintaining just as much clarity and readability as the full-colour PDF did. Convenient, huh?
