How to Remove Annotations from a PDF (Comments, Highlights & Markup)

A PDF that's been through a round of review usually comes back covered in sticky notes, highlighted passages, and reviewer comments — useful while the document was in progress, but not something you want in the version you send to a client or file away for the record. The FlexFiles Remove Annotations tool strips that markup out in seconds, free, right in your browser, and lets you choose exactly which categories to clear.

What Counts as a PDF Annotation?

Everything layered on top of a PDF's original content — not part of the page itself — counts as an annotation. FlexFiles groups them into five categories you can clear independently:

Highlights & text markup — highlight, underline, strikeout, and squiggly marks a reviewer draws over text.

Comments & sticky notes — the small yellow notes and callout boxes reviewers leave with feedback.

Drawings, shapes & stamps — freehand ink marks, shapes, approval or rejection stamps, and file attachments.

Fillable form fields — text boxes, checkboxes, dropdowns, and signature fields built into the PDF.

Hyperlinks — clickable web and email links embedded in the document.

None of this touches the PDF's actual text or images. Annotations sit on a separate layer above the page content, which is exactly what makes it possible to remove them cleanly without altering anything else on the page.

Why You'd Want to Remove PDF Annotations

Sending the final version. A contract or report that went through several rounds of review often has the reviewers' highlights and comments baked in — markup that was never meant for the person it's actually being sent to.

Archiving or printing. A document you're filing away or printing for a physical record looks cleaner, and prints cleaner, without yellow highlight boxes or sticky-note icons scattered across the page.

Converting to another format. A PDF you're about to convert should usually carry over only its actual content, not a reviewer's markup, so clearing annotations first keeps the converted file focused on what matters.

Protecting what reviewers wrote. A comment thread discussing deal terms, pricing, or internal feedback shouldn't travel with a PDF once it leaves the team that was reviewing it.

Clearing stale links. Hyperlinks in an older PDF can point to pages that no longer exist. Removing them wholesale is faster than tracking down and fixing each one individually.

How to Remove Annotations from a PDF Online

Clearing annotations with FlexFiles takes four steps:

1. Open the Remove Annotations tool — no account required.

2. Upload your PDF by dragging it onto the page or clicking to browse.

3. Choose what to remove. All five categories — highlights, comments, drawings, form fields, and links — are checked by default. Uncheck anything you'd like to keep, and enter the file's password first if it's protected.

4. Click Remove, then download the cleaned PDF once FlexFiles finishes processing it — ready to send, archive, or convert.

What FlexFiles Always Protects, Even If You Remove Everything

Two categories get special handling that goes beyond a simple on/off toggle, because getting them wrong has real consequences.

Redaction marks are never just deleted. If a reviewer placed a redaction annotation to black out a sensitive paragraph, deleting that marker without applying it would leave the hidden text fully intact and readable underneath — defeating the entire point of having placed it. FlexFiles applies every redaction mark it finds, permanently removing the content underneath rather than just the visual marker, before anything else runs.

Signed signatures are never removed. Checking Fillable form fields clears out unused text boxes and dropdowns, but any field that's already been digitally signed is skipped automatically. Deleting a signed signature field would invalidate a legally meaningful signature with no way to restore it, so FlexFiles leaves signed fields exactly as they are and only removes the ones still waiting to be filled in.

Removing Annotations vs. Flattening a PDF

Remove Annotations and Flatten PDF solve a similar-looking problem in different ways, and the one you need depends on what you're trying to keep.

Remove Annotations deletes the markup entirely. The highlights, comments, stamps, and form fields are gone, and the PDF goes back to looking like it did before anyone reviewed it.

Flatten PDF keeps the markup but makes it permanent. Annotations and filled-in form values get merged into the page content itself, so they display correctly everywhere but can no longer be edited, moved, or deleted by whoever opens the file next.

If you want a reviewer's highlights gone, use Remove Annotations. If you want to keep what was marked up but lock it in place so it can't be changed or stripped out later, flattening is the better fit.

Conclusion

Reviewer markup is useful while a PDF is being worked on and unnecessary once it's done — a document covered in highlights, sticky notes, and comments doesn't belong in the version you send, print, or archive. The FlexFiles Remove Annotations tool clears it in one pass, with control over exactly which categories you clear and built-in protection for anything redacted or digitally signed.
