Compressing a PDF / reducing file size

The compress PDF (reduce file size) feature will make your PDFs smaller.


Compressing a PDF File

Step 1 - Open the Compress Tool

  • Click on Create & Convert
  • Choose Compress.




Step 2 - Set compression quality

You can decide how much you want to compress your file. Keep in mind that compression happens by lowering the quality of the graphical parts of your PDF. 

  • Choose the level of compression.




You'll see an estimate for your new file size.


Step 3 - Confirm Compression

You're now ready to reduce the file size of your PDF. 

  • Choose Reduce file size.




Step 4 - Get your compressed PDF

In this step, the instructions change slightly depending on if you are using Soda PDF Desktop or Soda PDF Online


Soda PDF Desktop

The last thing to do is to choose where to save the compressed copy of your PDF.

  • Choose a Save Location on your computer.
  • Click Save.




The new compressed PDF will be saved to that location. The file will also open in Soda PDF ready for you to review.


Soda PDF Online

Your newly compressed file will open in Soda PDF Online. You'll see _reduce added to the file name.




You can now download the newly compressed PDF document. 

  • Click the save button at the top and your file will download to your device.




Alternatively, you can save a compressed version of your document using the second-highest compression selection:

  • Navigate to the Main Menu.




  • Click the Save Optimized option.

Batch functionality is temporarily unavailable in the Soda PDF Online. We are working on adding this feature as fast as possible.


We have two additional modules. The OCR module allows you to recognize and edit text within any scanned document or image. We also have the E-Sign module that allows you to electronically sign PDFs and track and manage e-signatures in real-time. If those modules are not available for you, you can purchase them here.
