Remove Annotations
Remove Annotations strips the annotation layer from a PDF: comment bubbles, highlights, sticky notes, drawn shapes and the interactive form widgets, which are annotations too. The result is a clean copy with only the original page content.
How to use Remove Annotations
- Upload the PDF you want cleaned.
- Run the tool; it counts and removes the annotation objects on every page.
- Download the cleaned document and confirm the comments are gone.
Where Remove Annotations is useful
- Sending out a reviewed contract without internal comment bubbles.
- Cleaning highlight layers left by a previous reader.
- Removing interactive form widgets before archiving a document.
Formats, algorithms and limits
Annotations are stored in a separate /Annots array per page rather than in the page content, which is why they are layered on top of a document and can be hidden. The tool deletes that array on every page and clears the AcroForm dictionary, then re-saves the file with compressed object streams.
Troubleshooting and honest limits
- If a mark was drawn directly onto the page rather than added as a comment, it is page content and will not be removed — use redaction or an image-level clean-up instead.
- Fields are removed with their widgets, so a cleaned form is no longer fillable.
- Save the annotated version first if you need the review history.
Frequently asked questions
Does removing annotations also remove highlights?
Yes. Highlights and text markups are annotation objects, so they are stripped together with comments and sticky notes.
Why is a mark still visible after cleaning?
It was probably flattened into the page content at some point, for example by a print-to-PDF step. Those marks cannot be separated from the page any more.
Will the form fields be removed?
Yes — field widgets are annotations, so the interactive layer is cleared with them and the document becomes a static PDF.
Does this reduce file size?
Usually a little, because the annotation objects and their appearance streams are no longer stored.
