After all, each solution shrinks your PDF file to a certain extent.

#1 Optimize your PDF File with Adobe

Adobe provides the option to optimize your PDF file by removing unused space and other optimization parameters. It can be found in 3 ways:

  2. Go to Tools -> Optimize PDF > Advanced Optimization > Audit Space Usage.
  3. Click on View > Show/Hide > Navigation Panes > Content > choose Audit Space Usage from the Content pane’s navigation menu.

#2 Decreasing the PDF File Size Using Google Chrome

Many of you might be unaware of this smart technique. By opening the PDF files and using the print option in Google Chrome you can easily split, extract, and print the files. Follow the steps to know how to reduce the pdf file size by using Chrome.

  • Locate the PDF file on your system and open it with Google Chrome.
  • Click on the Print option or press “Ctrl+P”.
  • The print window will open, now select “Custom” in place of “All Pages” and enter half of the pages your PDF has (if your PDF file has 20 pages, enter 1-10).
  • After the process finishes, at last, hit the Save button.
  • Do this process for the other half (11-20) and save it in another PDF file.
  • With this, you now have 2 PDF files with half the size of the original PDF file.

#4 Use Web-based PDF Compressor Tools

This method is for those who don’t have the Adobe Acrobat DC and DC Pro versions. Here the user can type & search for a web-based tool to compress PDF files in the browser and use the official Adobe online version. However, most of these online compressors have a file limitation that can split a PDF of size 100 MB or less. So, if you have a PDF file size exceeding 100MB, then this solution is not for you.

  1. Search for the online Adobe Compress PDF size tool.
  2. After opening the website, drag and drop your PDF file to the given space.
  3. Or, click on Select File to add the PDF file manually from your system.
  4. Once added, choose the Compression level: High, Medium & Low.
  5. Do understand that the PDF quality will take a hit the higher the compression level.
  6. Click on Compress.
  7. Congratulations, you have successfully reduced the size of your PDF file.
