One of the best ways to save space on your Mac is by reducing the size of large PDF files. When it doesn’t help even after unloading the trash and deleting apps, this can help you to free up some extra space for your new project. At the same time, the chances are that the compressed version may lose the actual quality of content. Found a way to do this without compromising on quality. Let us guide you on how to reduce PDF file size on Mac.

How to Reduce a PDF File Size on Mac Using Preview

The Quartz Composer API supports processing and rendering graphical data and allows developers to create custom patches for the Quartz Composer developer tool. ImageKit provides user interface support for browsing, editing, and saving images, showing slideshows, and browsing and previewing Core Image filters. What is a Quartz Filter? Quartz is the rendering engine of Mac OS X. Built into Mac OS X are special filters you can use to perform a variety of tasks. Shrinking PDF files is one of those tasks.

1. Open the PDF file you want to compress.
2. Click on File from the top menu.
3. Click Export.
4. Give a name to it and add tags if you want.
5. Set the right location to save it on your Mac.
6. Click on the bar next to Quartz Filter.
7. Select Reduce File Size.
8. Click on Save.

The file will be exported to your selected location. You can figure out the size difference between the original pdf and the compressed version. To do so, right-click on the file → click Get Info from options, view the file size next to the pdf name.

When you open the compressed file, you may notice the quality of the content lacking details (mostly images and visuals) as compared to the original version.

Product Description

Quartz fiber filters are made of very pure quartz fibers with no binders and glass fibers. The pure quartz composition prevents the filters from reacting with acidic gases, unlike glass fiber filters that can react and cause false readings. This makes quartz filters well suited for measuring heavy metal concentrations and small amounts of particles. Because of the low level of alkaline earth metals, ‘artifact’ products of sulfates and nitrates (from SO2 and NO2) are virtually eliminated. Quartz fiber filters are used for air sampling in acidic gases(except HF), stacks, flues and aerosols, particularly at high temperatures and in PM-10 testing as well as where absolute purity of the filter medium is required. The filters also exhibit good weight and form stability.
