How to compress pdf files?

The Compress PDF tool enables you to reduce the size of PDF files by compressing objects and images. 

To use the tool to compress PDFs you need to take the following steps:

Upload files to Compress PDF

  1. Upload the PDF files to be compressed. There are a few ways you can go about this:
    1. Drag files into the browser for example from your Desktop, or Windows Explorer or Finder on Mac.
    2. Click "Browse" to open a file picker and select files from your computer.  You can select multiple files at once.
    3. Upload files from Google Drive or Dropbox by clicking on their respective icon in the upload area.  You will need to authenticate with the corresponding cloud service and then select the files from the interface that pops up.Compress PDF options
  2. Specify the Compression Level. The compression level can be specified as either "Default" or "Aggressive". The default option preserves good image quality for screen reading, whereas the aggressive option can lead to much more compressed PDFs but sometimes with noticably worse image quality.  We recommend the Default option for most users. If using Aggressive, we recommend taking a good look at the output to make sure the image quality is sufficient.
  3. Click "Compress PDF" to go ahead and perform the compression.

You will then be redirected to the download page where you can download the compressed PDF files once it has been processed.  The file names refer to the original file name and the page range specified (origfile_compress.PDF).  Simply click on Download to download each file.  Note that you need to be logged in with an account to be able to download files.  If you do not have an account, you can sign up for one and download your file right away.

Once you are done, you can click "PDF Tools" to navigate to other PDF tools, or to go back to compress another file, simply click the Compress PDF link.  If there was something wrong and you want to change the compression level, you can use the "Do over" button.  It brings you back to Compress PDF but keeps all the uploaded file in tact, so you can change the compression levels without starting from scratch.
