what are the best ways to reduce a pdf's file size?

When it comes to sharing documents, pdf's are an invaluable asset. Not only are they easy to access and share, but they're also capable of being securely transferred over the internet. However, if your pdf document is just too large for you to send as an attachment in an email, or if you're trying to minimize the storage space a particular pdf takes up on your computer, compressing the file size of a pdf is an important consideration.

Fortunately, there are several methods you can use in order to reduce the file size of your pdf. Let's look at some of the best ways to do this.

1) The first approach is to use online or software compression tools. These tools can be found in abundance online, and can range from free or simple-to-use applications such as Adobe's Acrobat DC app, all the way to professional ones like Zamzar. These platforms allow you to select a document in your local folder (or remotely upload it), and then compress it automatically based on user settings. When finished, you can either download the smaller version of the pdf file directly from the source page or have it sent directly to your email box.

2) Another approach is to scan physical copies of documents and then save those files as PDFs. By turning paper documents into digital versions such as PDFs you can also compress them by changing their resolution before sending them over as documents. For instance, scanned images have high resolutions which contributes a lot on generating larger sizes; Whereas lower resolutions could allow for much lower file sizes even for multi-page documents when saved as a PDF file format - making this a great way I reduce size without losing any important visual information in them.

3) A third option available is using dedicated tools like JBIG2 that are specificerally made for reducing pdf files' sizes without any loss of quality or data (this option might require prior knowledge with certain programs). Programs like these use advanced algorithms that compact data within PDFs so less storage space is taken up by them while still achieving good fidelity in how they look when opened with other programs capable of reading & opening such files (Adobe Acrobat is one example).
