Starting with a large file size can be daunting, especially when it comes to sharing important documents. PDF files can easily become too large to send by email or upload to a website. Luckily, there are ways to compress PDF files on Mac. In this article, we will guide you through 12 easy steps on how to reduce PDF file size on Mac.
Steps
Step 1: Open the PDF file in Preview
The first step to reducing the file size of a PDF on a Mac is to open it in Preview. Preview is a default app on Mac that allows users to view and edit PDF files.
Step 2: Go to the “File” menu
After opening the file, go to the “File” menu, located on the top left corner of the screen.
Step 3: Click on “Export”
From the “File” menu, click on “Export”. This will bring up a window where you can choose the format and options for exporting the file.
Step 4: Choose “PDF” from the format menu
In the export window, select “PDF” from the format menu.
Step 5: Click on “Quartz Filter”
Under the format menu, click on “Quartz Filter”.
Step 6: Select “Reduce File Size”
From the Quartz Filter menu, select “Reduce File Size”.
Step 7: Save the file
After selecting “Reduce File Size”, save the file by clicking “Save”.
Step 8: Check the file size
To see if the file size has been reduced, right-click on the file and select “Get Info”. The information window will display the file size.
Step 9: Use online PDF compression tools
If the above steps do not significantly reduce the file size, there are several online PDF compression tools available that can further reduce the file size.
Step 10: Delete unnecessary pages
Another way to reduce the file size of a PDF is to delete unnecessary pages. This can be done using Preview, by selecting the pages that need to be deleted and pressing “delete” on the keyboard.
Step 11: Use grayscale instead of color
If color is not important for the document, convert it to grayscale. This can be done using preview, by going to “File” > “Export” and selecting “Grayscale” from the “Quartz Filter” menu.
Step 12: Use a PDF optimizer tool
There are various PDF optimizer tools available that can further reduce the file size of a PDF on a Mac, such as Adobe Acrobat Pro DC. These tools often have advanced settings that can be customized to fit your specific needs.
Explanation
When a PDF document is created, it can contain images and other elements that contribute to a larger file size. To reduce the size of a PDF file on a Mac, it is important to use compression methods that do not compromise the quality of the document.
Using a Quartz Filter allows users to compress the file size while maintaining the document’s quality. Quartz Filters are built-in compression methods that can be selected from the “Export” menu in Preview. By selecting “Reduce File Size”, the document size can be reduced significantly.
Deleting unnecessary pages and using grayscale instead of color are also effective ways to reduce the file size of a PDF document. For documents that require advanced customization, using a third-party optimizer tool may be the best option.
Tips and Tricks
Tip 1: Scan documents with a lower resolution
When scanning a document, reduce the resolution to a lower quality. This will create a smaller file size without compromising the readability of the document.
Tip 2: Use Adobe Acrobat instead of Preview
Adobe Acrobat has more advanced compression settings than Preview, which can result in a smaller file size.

Tip 7: Use font subsetting
Using font subsetting, which only includes the font characters used in the document, can significantly reduce the file size.
