We currently use different documents to exchange, manage and receive information through the network. There is no doubt that PDF (Portable Document Format) files are one of the most popular standards today and it is thanks to their security features, compatibility and size that they allow. These are some of the reasons that make users lean towards its use in the management of different types of data..


PDF files are files whose format is of the compound type since vector images, bitmap and text are integrated into one and hence their importance and their wide use for many types of data.

Let's see how to compress our PDF files with Smallpdf.




How to compress a PDF file in Smallpdf


Step 1

Once we access the indicated URL, we will see the following. There it is possible to select the PDF file in two ways:
  • Clicking on "Choose files" and go to the folder where the PDF file is
  • Directly drag and drop the PDF file




Step 2

If we select the option "Choose file" the following window will be displayed to go to locate the PDF. We select it and click Open.




Step 3

To check how Smallpdf works, we can go to the PDF properties by right clicking on it and selecting "Properties" to see its current size: In this case it is 1.17 MB.




Step 4

Once we select the file, it will be uploaded to the Smallpdf servers:




Step 5

When the file has uploaded we will see the following:
  • On the left side we find the name of the file and its current size
  • On the right side we can select the type of compression to use


Types of compression
Smallpdf offers us two types of compression available:
  • Basic compression: this reduces the file size by up to 49% (the utility gives us an estimate of the final size of the PDF file)
  • Large compression - offers up to 75% reduction in size, but is only available in the PRO version of Smallpdf




Step 6


In case you want to use the PRO version, the following options are offered:
  • One year for $ 108
  • Monthly USD 12


It also offers us a 14-day proof of utility to make the best decision. In this case we activate the "Basic compression" box:




Step 7

Once selected we click on "Choose option" to give way to the compression process of the selected file. When this ends we will see the following.


There it indicates the percentage by which the PDF file has been reduced. As we can see, the size is a few KB and at the bottom there are other options to work with the compressed PDF such as sharing it by mail or with a link, adding a digital signature, etc.




Step 8

We click on "Download" to access our compressed file, but if we click on the drop-down arrow we can select:
  • Save the file to DropBox
  • Host it on Google Drive
  • Save it locally on your computer




Step 9

We click on "Save to device" and it will be downloaded locally:




Step 10

We can click on the compressed file to see that it preserves the original quality and attributes:




Step 11

Smallpdf adds the –compressed line to the downloaded file, if we access the properties of this new compressed file we will see how much it has been reduced and what its new size is:




We can see that now the file went from 1.17 MB to only 293 KB which is a considerable reduction. If the files we work with must be managed through email or on web platforms where sizes have many limitations, it is interesting that we know how to compress them in a simple way. That is why thanks to Smallpdf this will no longer be an impediment to using PDF files.


Let us remember that it has a 5 GB limitation, but without a doubt that it will be very useful for all of us and not only in compression but in everything that this valuable online utility integrates.
