Working with PDF files is the order of the day: manuals, long texts, documents, etc. Also, you will know that it is easy to create this type of file from any computer. Now, being able to customize them is somewhat more difficult. And one of the main problems, to call it something, is the weight that some of these files get. However, if you have a Mac, we will make it easy for you and try to reduce this final size.

We have already spoken on different occasions that some of the tools that macOS offers as standard are very powerful: signing documents without having to print would be an example of this. And the possibility of being able to work with PDF documents is also considered. In this case, what we will do is reduce the size of a PDF. Although, we warn you: you will not be able to say the final size; the process is automatic and everything will depend on each file. That is, in some cases, we can get a lot of reduction, while in others it is possible that we get a few MB less.

Likewise, you should also take into account that the weight reduction will affect the quality of the document. Therefore, it is very possible that if it is only text it will be less noticeable, but if the file includes images, the quality of these will surely be reduced. With that said, let’s move on to action:

Open the PDF document with Preview. If you have not touched any of the settings, double-clicking will surely open it with this function. The next thing is to go to the top menu bar and click on “File”. Once the list of options is displayed, the one that interests us is the one that indicates «Export».

You will see that a new window with different options opens. What interests us about it? The box indicating “Quartz Filter”. Different alternatives are shown again, but the only one that interests us in this regard will be the one indicated by “Reduce File Size”. By checking it, the only thing left for us to do is click “OK”. The result, as we were telling you, will depend on each case.
