It's impossible to recommend what would work for you. 2.5 MB - Print Low Quality, followed by Reduce File Size.5 M - Export High quality, followed by Reduce File Size.I did a short test with horribly large PowerPoint file filled with pictures. Image Compression - JPEG quality medium.Image Sampling - scale to 50% (max of 512x128 pixels), and.I assume Reduce File Size simpy performs both: Save it as "Save as Reduced PDF" and now, the print dialog PDF drop-down will show both options: Now, just go to the Print dialog and you'll see a new option to "Save as Compressed PDF".įor even smaller files, with even worse image quality, replace step 3 above with Apply Quartz Filter to PDF Documents, select Filter Reduce File Size followed by Move Finder Items as before:.And under it, drag-and-drop Move Finder Items to Desktop.Drag-and-drop Compress images in PDF Documents and select Compression as JPEG and Quality Least.Under File > New, create a new Print Plugin:.If you don't like the two step process, then create a simple Automator script! Nice! Automator Print Plugin to Compress PDF Open the PDF in Preview, File > Export., select Format as PDF and Quartz Filter to Reduce File Size: Then use Preview to further compress the PDF.from the Print dialog, select the PDF drop down > Save as PDF, Open the PDF in Preview, File > Export., select Format as PDF and Quartz Filter to Reduce File Size.įor other apps that support printing, to force highest (lossy) compression of images, do the same: It's not so easy with Word - you can Compress Pictures from the Picture Format ribbon, but that means you'll loose the original high-quality image. Under Preferences > General select Low Print Quality (Paper/PDF).PowerPoint PDF Compression Settingīefore going on, if you're using PowerPoint then there is a Low quality setting for the smallest PDF size:
Also, do not forget to check out how to change the default PDF Reader on Mac, and how to share Apple Music Playlist with Friends on Mac.Did you know you can (sometimes) shrink the size PDF files by apply lossy compression to images? This is a built-in capability with macOS - no third party tools required.
That is everything you need to know about how to reduce PDF files on a Mac computer. In the case of PDF documents with very heavy images, compression can be as high as 70%. The overall reduction that can be achieved depends on various factors, including of course the resolution of the images embedded in the original PDF. To save the new compressed file just choose “Save” from the File menu.The overall size of the file will be compressed.In the window that appears with the PDF, just click “Filter” in the bottom menu, choose “PDF Reduction”, click “Apply” and wait a few seconds.To compress a file, just drag a PDF to be compressed into the “ColorSync Utility” or choose the “Open” item from the “File” menu.The filter will now be available at any time without having to recreate it from scratch. This is the option that normally allows you to reduce images without impacting too much on quality. Click on the triangle to the left of this name to show the compression options, move the quality slider to the intermediate position before the maximum. At this point, the “Image Compression” option remains.Delete the first line (just click on the “x” to the right of the name) You will see two options: “Image Sampling” and “Image Compression”. Click on the triangle to the left of the word “PDF Reduction”.
Now, if you are looking to reduce the PDF file size on your Mac computer, you can use ColorSync Utility to do so and apply it in Preview. It is very simple to create PDF files, especially from a Mac that supports this format directly in the operating system (from any application that allows you to print, you can export a PDF file).
