This article provides four solutions about how to reduce PDF file size on Mac, Windows, iPhone, and online. Two of the WorkinTool software are similar in that they both support batch compression, which means you can compress multiple PDF files simultaneously. It’s convenient when you’re dealing with various PDFs. However, there are slight differences between them. Because WorkinTool File Compressor is a professional compression software, it has more than three compression levels. Users can see the PDF file information in the process window. This is what the PDF converter doesn’t have.

But no matter which tool you use, we guarantee you’ll have an excellent compression experience. More importantly, these four desktop and online compression tools are all free (The iPhone’s built-in software File also has no usage restrictions).
