Editing a flattened PDF prevents all markups from being unflattened.
Bluebeam® Revu® all versions
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
- 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.
