How to Convert PDF to Black and White on Mac

PDFs are a universally accepted file format, widely used for sharing and printing documents while maintaining their original formatting. Sometimes, you may need to convert a colored PDF to black and white, perhaps to save on color ink during printing or to enhance the readability of the document.

If you’re a Mac user, you’ll be glad to know that there are several methods to accomplish this task. This post will guide you through the process using macOS’s built-in Preview app, Adobe Acrobat, and third-party applications.

Converting PDF to Black and White using Preview

Mac’s built-in Preview application isn’t just a PDF viewer; it’s also a powerful tool with many handy features, including the ability to convert colored PDFs into grayscale.

Step 1: Open Your PDF in Preview

First, open the PDF you want to convert in Preview. If it isn’t your default PDF viewer, right-click the PDF file, select ‘Open With’, and then choose ‘Preview’.

Step 2: Access the Export Menu

Once the PDF is open, navigate to ‘File’ in the top menu and then click ‘Export’. A dialogue box will appear.

Step 3: Convert to Black and White

In the export dialogue box, click the ‘Format’ drop-down menu and select ‘PDF’. Next, click on the ‘Quartz Filter’ drop-down menu and choose ‘Black & White’. Click ‘Save’ to complete the conversion.

Converting PDF to Black and White using Adobe Acrobat

Adobe Acrobat is a comprehensive tool for working with PDFs, including converting colored PDFs into black and white.

Step 1: Open Your PDF in Adobe Acrobat

Begin by launching Adobe Acrobat and opening the PDF you wish to convert.

Step 2: Access the Convert Colors Tool

Once the PDF is open, navigate to the ‘Tools’ pane and find ‘Print Production’. If you can’t see it, click the small icon at the bottom left of the pane to open the full list of tools. Once in ‘Print Production’, click on ‘Convert Colors’.

Step 3: Convert to Black and White

In the ‘Convert Colors’ dialogue box, select ‘Gray Gamma 1.8’ for the ‘Conversion Profile’ and ensure the ‘Convert Colors to Output Intent’ option is ticked. Click ‘OK’ and then save your document to complete the conversion.
