powerpoint for mac became black and white

In this quick guide, we will introduce two methods that can convert color PDF files to Black White or grayscale using Preview and Adobe Acrobat Pro DC on Mac.

Here you can choose a different file name, location, output format and Quartz filter before you save the file to your computer.

The format should default to PDF, so you dont need to change it.

You need to manually choose Black and White or Gray Tone from the list of filters.

Currently you need to firstly convert PDF file to image file in Preview, then convert the image file to PDF and apply the Quartz filter at the same time.

This workaround works only if you have a few PDF pages to convert.

Open the PDF file in Acrobat Pro, click Tools, choose Print Production.

You can then access the tools to preview, preflight, correct, and prepare PDF files for high end print production at the right panel.

You will get a pop-up dialog where you can choose Gray Gamma from the Conversion Profile.

Press OK to continue and convert color PDF to grayscale using Acrobat Pro on Mac.

Click the Fixups (spannerwrench icon) and then type in convert to find Convert color to grayscale or Convert color to BW.

Click Fix button at the bottom right corner and follow on-screen tips to convert color PDF to black and white or grayscale and save it to your Mac computer.
