We would like to have seen a few more configuration options and maybe the ability to view changes in full screen, but as far as basic compression goes, PDF Compressor is a good choice. IT is easy to use, with a simple, plain interface that can be navigated by users of all levels of expertise. Overall, PDF Compressor is a lightweight, streamlined size reducer for your PDFs. You will now be prompted to choose a destination folder for your files and the app compresses your files as you requested. As soon as you have made your configuration changes, you just hit Compress. This is a simple way to reduce or increase the percentage you want alter in your document. You are next presented with a slider, which you are able to define the level of quality you need for your files. If you choose to add more than one file then you are presented with a preview in separate tabs. A document with many images will take longer to compress. Heres an example of a grayscale converted image: To use this option select grayscale as image conversion. This can be done either by drag and drop or by using the explorer interface. For lower PDF sizes, when having a lot of images, you can convert images to grayscale. The main interface comprises of a medium-sized, non-adjustable window that shows a simple button, until you add files to it. This has happened to me several times, fortunately while experimenting and not with actually valuable archival PDFs.PDF Compressor comes with an intuitive and easy to use interface that makes it suitable for both for experienced and inexperienced users. There was nothing worse than finding a reduced version was too reduced and that it is now the only version of the file I have. One other thing I’d say is to make sure you have backups of the original files. Believe the warning it gives that your original full quality version will be no more if this one is your only version. Use a copy of the file as PDF Expert does alter the file you are reducing. That lead me to finally finding this app. I’ve destroyed all quality using built in filters in Preview with no discernible reduction in file size. Previous experiments in macOS were quite disappointing. I’ve previously tried the method used in this article, but must admit I did not try it just now in Catalina. The “Medium Quality” file (96% reduction) was 2.5MB and was still very good. Moments ago I was testing a 75MB PDF with text and images and was able to reduce it to 5MB with minimal impact on quality using the “High Quality” setting (93% reduction). Its auto reduce file size is the best I’ve found, and I have tried many over the years. I have used PDF Expert by Readdle for reducing hi-res PDFs to a reasonable size for around 4 years now. This setting is not just good enough for retaining any detail. The default option to “Constrain Size” is set to a max of 512 pixels, which explains why you are getting poor quality PDFs when reducing the file size in Preview. Expand the filter by clicking the arrows on the left, so that you can see the details. Go to the Filters tab and find the Reduce File Size option in the filters listģ. From “Applications > Utilities,” open the ColorSync UtilityĢ. By doing this, you’ll give yourself more filter options for the Preview export:ġ. You can inspect it and copy it and adjust the settings to create additional filter options. It is here that this Reduce File Size filter option is specified.

This is where the Mac standard ColorSync Utility can help you out. The problem here is that this standard option does not give you control over how much to lower the quality in order to reduce the file size, and this standard option will leave you with a very small file of very poor image quality.
