Editing a flattened PDF prevents markups from being unflattened | Revu 2019


Editing a flattened PDF prevents all markups from being unflattened.


Markups cannot be unflattened because editing a PDF’s page content changes the flattened markups. When flattening markups in Revu, please be aware that the following commands, if executed on a page containing flattened markups, will prevent all markups on the page from being unflattened:

  • Edit Text
  • Search and Replace
  • Erase Content
  • Cut Content
  • Repair Page Content
  • Color Processing
  • Redaction
  • Reduce File Size


If you intend to use these commands to edit a PDF that contains flattened markups, be sure to unflatten your markups prior to executing the commands. You can then re-flatten your markups afterwards. This will keep your markups recoverable.

Flattening Form Fields is always permanent. They cannot be unflattened under any circumstances.

Some markups cannot be unflattened in Revu after editing a PDF’s page content. Read on to learn why and how to keep it from happening.
