Compress Images

It’s said that among the main culprits of large PDF file sizes is the use of high-resolution images. While these photos may look great on your device’s screen, they can significantly increase the overall size of your PDF file.

To reduce the size of your PDF file, you can compress the images within it. This will reduce their resolution and file size without significantly affecting their appearance on screen.

Check out the app publisher’s site for any instructional guide or post covering how to use their product to compress images on PDF files.

Remove Data Redundancy

Another way to reduce the size of your PDF file is to remove data redundancy. This refers to any unnecessary or duplicate data within your file.

PDF optimization tools can help you identify and remove pieces of data that are redundant within your file. This can include duplicate fonts, metadata, and other unnecessary information.

In removing such data, you can significantly reduce the size of your PDF file without affecting its content, appearance, and how the intended audience will perceive it.

Update Your PDF To The Latest Version

Finally, updating your PDF documents can help reduce its size as well. This involves saving your file using a newer version of the PDF format that’s more efficient and produces smaller file sizes.

There you have it. The abovementioned are the different steps that you can follow in optimizing your PDF files.


Optimizing your PDF files is an easy and effective way to reduce their size and make them easier to share and store. By using the right tool, compressing images, removing data redundancy, and updating your file, you can significantly reduce the size of your PDFs without affecting their content or appearance.
