How do compress PDF files? One of the main reasons for using a PDF is because the file maintains its original formatting when you send it to another person. However, if you have a large document with graphics, it may be too big to send in an email. In this case, you will need to reduce PDF file size with a file compressor. In addition, larger files may also take unwanted time to download. Fortunately, it's easy to reduce size of pdf files with PDF Pro. However, you can also manually shrink PDF files based on the specific dimensions you prefer.

PDF ProTip: For best results, manually compress your PDF

While you can use online services like PDF Pro, the best way to compress your PDF is to manually reduce the size of the images before the PDF was created. There are two options here:
If you have the original file from which the PDF was created (for example, a Word file), first compress all the images before converting it to PDF. Right click on any image within a Microsoft Office document. On the image format tab, click the Compress Picture button. The image will be automatically compressed based on the parameters you define.
If you do not have the original file, convert your PDF to JPG. You can do this using PDF Pro. If your PDF includes multiple pages, each page will be converted as an individual JPG. Now compress the JPG(s) using a free online JPG compressor such as Compress JPEG. Lastly, convert the compressed JPGs back into a PDF.
