How to Freely Reduce the Size of a PDF File to Under 100 KB?

Why should you lower the size of your PDF files?

It’s critical to understand the benefits of compressing PDF files. First and foremost, data retention is regarded as the most crucial factor. When compared to the document’s data, reducing the file size has little impact. All of the data is preserved in its original form.

Storage comes in a close second. It’s considerably easier to keep several files and folders on cloud storage when they’ve been shrunk to a manageable size. As a result, getting a hold of them is a breeze.

Email attachments follow. Emailing little PD files is simple since they are small. The PDF files may be attached fast and simply and sent in a matter of seconds. The more data, time, and space a file takes up, the larger it will be.

Obviously, there are many more benefits to shrinking PDF files, but these are the most important ones.
Let’s have a look at some strategies for lowering the PDF file size now that you know the benefits.
