When you use basic compression techniques on a PDF, it will retain all its layers, editable objects, text, hyperlinks, bookmarks, form fields, metadata, etc. Flattening a PDF involves merging vector artwork and rasterizing images into one composite bitmap layer, eliminating separate layers and objects. Does compressing a PDF flatten it?Ĭompressing a PDF file does not flatten it by default. But excessive compression can degrade quality. The goal is to apply the optimal compression techniques and levels to minimize file size while retaining acceptable visual quality for the PDF’s intended use. Lossy Compression: Mathematical techniques like DCT achieve much higher compression ratios but introduce irreversible data loss. Object Simplification: Vector graphics, shapes, and paths can be simplified and numerically optimized to take up less space.ĭownsampling: Image resolution can be reduced to make raster images smaller, but this negatively impacts quality. Metadata Removal: Non-essential information like author name, creation date, etc., can be stripped out to reduce size. Text Compression: Repeated text strings get encoded efficiently using compression algorithms applied to the text content. This shrinks image data.įont Compression: The fonts used in the PDF can be subset and compressed so that only characters used in the file are embedded instead of the entire font file. Image Compression: Any raster images (like JPEGs or PNGs) embedded in the PDF will be compressed using algorithms that reduce file size while trying to maintain quality. When you compress a PDF file, several techniques are employed to reduce its size while trying to maintain acceptable quality for its intended use: What happens to a PDF when you compress it? Both of them are excellent at compressing PDF files and, at the same time, maintaining the quality close to the original. To reduce the size of a PDF on MacOS without compromising the quality too much, you can use the Lightweight PDF app or Adobe Acrobat’s online PDF compressor. Some Tips on Compressing PDFs on a Mac How to shrink a PDF on a Mac without degrading its quality Getting Started with Your New Mac: A Switcher's Guide (35 downloads)Īs you can see, the clear winner is Adobe, which is unsurprising given Adobe Acrobat’s long history of dealing with PDFs. I chose the following PDF file for the compression test, which has an around 1000-word guide for new Mac users, especially those who are switching from Windows: I decided to go ahead and compare the result of the three methods. So, Which PDF Comparison Method is the Best? Choose one, and your files will be compressed accordingly. It will give you three compression options. Head over to Adobe’s website and upload your PDFs. You can use Adobe Acrobat online for free to compress PDFs. Method 3: Adobe Acrobat PDF Compressor Online To add a custom filter, please see the answers to this question here. You can add custom filters to improve the quality of the compressed PDFs. This happens because the default filter used when converting has minimal quality settings. While this method is easy and free, I have to mention that I was not satisfied with the quality it produced. Then select PDF, and Under the Quartz Filter dropdown, select Reduce File Size. Click on the File menu and select Export. ![]() To do this, right-click on the PDF and select Open with Preview. Open the PDF you want to compress with Apple’s Preview App.Sure, some options for controlling the compression quality would be nice, but if it’s giving me the highest quality possible while shrinking the PDFs by more than 50%, that’s good enough for me. More often than not, it compresses the PDFs by more than 50% without compromising much with the quality. Without presenting me with any options regarding compression or anything else, this app does what it says. I personally liked the simplicity of this app. I suggest you make a copy of your original files, put them in a different folder, and then compress the files with this app. This might be a problem if you, for some reason, are not happy with the converted files. So the original files are overwritten by the converted ones and are gone forever. Lightweight PDF compresses and replaces the original files. There is a caveat, though, which you need to be mindful of. This is the most straightforward way to compress your PDFs.Īll you need to do is drop all your PDF files on it, and it converts them. ![]()
