This trick works in virtually all versions of Preview on all versions of Mac OS system software, be it macOS Mojave, High Sierra, Sierra, El Capitan, Yosemite, Mavericks, Mountain Lion, Snow Leopard, etc. Preview is a great app on the Mac with a huge variety of features as well features, and it is more than capable of processing and viewing many image formats and PDF files regardless of their size. * Note that if the Preview app is no longer the default application associated with PDF files, you can reset the default PDF viewer in Mac OS to Preview with these instructions. On the Mac, that’s pretty easy to do with the “Get Info” command, select the PDF file in the Finder, and go to the “File” menu to choose “Get Info.” This really depends on the application that created the PDF to start with and whether or not the file is compressed at all, but for situations where a PDF is generated using something like Adobe Acrobat Pro, it might be.Įither way, you may want to get the file size of the documents in question both before and after compression. This works particularly well for reducing the size of text-heavy PDF files, but it’s not a perfect solution for every document out there so you’ll want to go through the process with the document in question and compare it to the original PDF to see if it helps or if the quality of the output reduced PDF file is sufficient for your needs.Ĭounterintuitive and in some less common situations, starting with an already optimized and compressed PDF file can result in the generation of a larger file with this reduction filter. You don’t want to overwrite the original PDF file with the compressed version without knowing if the quality is up according to the standard you need.įor PDF files that are not yet optimized, the Preview app in Mac OS X can often significantly reduce file size by running it through an export filter as described, sometimes reducing a document by 40% or even more than 90%, depending on the PDF file and its content.
Again, this is an advantage to using the “Export” command as you can easily compare the two documents when it is done, which is recommended.

That is not always desirable, which makes this trick best for PDF files containing a lot of text, simple charts, graphs, spreadsheets or simple vector drawings, and not for full graphics or photos where high image quality is desired. Keep in mind that quartz filters are basically image processing filters, but unlike apps created for lossless image compression, the PDF file is processed in such a way that it can result in lossy compression and artifacts appearing on embedded images. For all-text original documents, such as a resume or a Word document converted to a PDF without any optimization, this can make a huge difference, and a file size of 1MB may be smaller. How much space you save by using this file reduction filter varies greatly depending on the content of the PDF, the original app that created and saved the PDF, and whether filtering was applied to begin with, among a number of other factors.
