Compressing a PDF file may be a necessity before transferring it by email, for example, or to successfully copy it to an almost full USB key. There are multiple tools to reduce PDF size. You can use tools like PDFCreator or PDF24Creator available on PC. These are software that offer very fine adjustment options, but which can also lose neophytes.

How to reduce the size of a PDF?

The simplest solution for many people is to go through an online service such as SmallPDF, iLovePDF, or PDF2go. However, unlike dedicated software where your files do not leave your hard drive. These sites ask you to transfer your documents to them. Depending on your sensitivity, it is up to you to judge the potential risk. However, the latter remains weak and we have chosen here the online compression service offered by Adobe.

  • Once the file upload is complete, click the button Compress located on the right. The processing will take a few seconds or even a few minutes depending on the size of the files and their complexity.

Any compression leads to a degradation of quality, if this should not pose any problem with a “text” document: at worst, the characters will be a little less “clean”.

If your PDF includes a lot of images, it can make it look less beautiful. So, remember to test the different compression modes in order to find the best quality/size ratio.
