How to Flatten a PDF

There are numerous ways to flatten a PDF. The easiest way is to use the Print PDF module in Adobe to do this. In short, you are exporting the file to a printer and saving it again as a simple PDF with no layers.

eSubmission flatten PDF
  1. Open the PDF to be flattened in Adobe Acrobat DC, Pro DC, or an older version.
  2. Use the "File" → "Print" menu to summon the "Print" dialog. Make sure you change the Printer name to Adobe PDF.
  3. Change any parameters that you need to, such as orientation, page range, size, and so on.
  4. When you click the "Print" button, it will ask you for the target folder to save the file in. You can also rename the file to preserve the original. Hit Save and you are done.
