PDF Annotator vs. PDF Editor: What Is the Difference?
A PDF Annotator and a PDF Editor are related tools but they are not exactly the same.
| Feature | PDF Annotator | PDF Editor |
|---|---|---|
| Highlight text | Main use | Often available |
| Add notes and comments | Main use | Often available |
| Draw and mark pages | Main use | May be available |
| Add shapes | Common feature | May be available |
| Change existing PDF text | Not its main purpose | May be supported |
| Change document content | Usually adds annotations | Can edit existing content |
A PDF annotator is best when you want to add notes, highlights or marks without changing the original text.
