Free PDF Compressor Online & on Windows/Mac

The PDF was first created by Adobe and was made to apply to more devices for information transfer. For now, it has become the most ideal and reliable file format for document sharing and information collaboration. It is safer than other office formats like Word since it is not supported for editing and works on most platforms. However, the size of a PDF is always too large because of the many images and graphics. You will always need a free PDF compressor to make PDF work easier.

This post will introduce four compressing tools for you. They can be used online or on a desktop. I hope you can pick a suitable one according to your needs.

Free PDF Compressor on Windows/Mac

#1 WorkinTool File Compressor

Works on Windows 11/10/8.1/8/7/Vista/XP, macOS, or later.

For the top spot for the best free PDF converter, I want to give it to WorkinTool File Compressor. The reason why I highly recommend it is that this tool is not just a normal PDF compressor. It is also an Image compressor, a video compressor. You can compress all the popular files in Office format.

When speaking of PDF compression, it offers three compressing levels for users to experience. They are Smaller Size, Normal Compression, and Clearer Output. Under ordinary circumstances, a Normal Compression is far more than enough for your PDF sharing and transfer. However, a Smaller Size is for a PDF file with only lots of text and characters. Because this mode is about to compress your PDF to the smallest, they might be damaged if your documents contain pictures. Clearer output is to compress files with quality assurance, which means if you care that the images in PDF will be altered or damaged, you can use this mode to compress your PDF file. This allows the software to compress it to the appropriate size for your own PDF size.

Guide to Using this Free PDF Compressor:

Step 1. First, open this amazing tool on your computer and select PDF Compressor.

  4. No internet is required.

#2 WorkinTool PDF Converter

Works on Windows 11/10/8.1/8/7/Vista/XP or later.

The next tool I will introduce still comes from WorkinTool – WorkinTool PDF Converter. As the name tells you, it is basically an all-in-one PDF management software. With this tool, you can do all the PDF operations that you can think of. For example, you can edit or convert it to other office formats, merge, or set a password. Indeed, you can also use it to compress your PDF. If you are constantly working with files in PDF format, I highly suggest you try this incredible PDF converter. I mean, lightweight software like this can solve all the PDF problems. How convenient is that?

But compared with the Special File Compressor, you may find it has only two compression levels. If you want to secure the PDF quality, you can only choose to use basic compression.

Steps on Using the PDF Converter:

Step 1. Find Compress PDF in the Tool Box, then click Select PDF file to import your PDFs or drop them into the program.

  2. Long-term free trial.
  3. The network disconnected to protect your files.
  4. Batch conversion is supported.
  5. All-in-one PDF management tool.

😢 Cons:

  1. Compression selections aren’t enough.

#3 WPS

Works on Windows 10/8.1/8/7/Vista/XP, macOS & Linux, or later.

When speaking of PDF compressing, you cannot miss WPS Office. Just like Adobe, WPS Office is also a well-known office software. But for the price reason, I still put WPS as the third-best free PDF compressor. After years of market research and experience, this company knows exactly what users want and need. So you can find all the possibilities on this famous software.

However, to support the R & D team, you can’t expect all of these functions to be free. You can’t use editing or converting without logging in to your account. For the compressing option, you need to apply for a free trial.

How to Use WPS to Reduce PDF Size:

Step 2. Then, select a compression level and click Compress in the process window.

Step 3. Lastly, check if the file size is changed in your save folder.
