Remove comments and annotations from a PDF

Published 2026-10-14 · How-to

A PDF comes back from a colleague or a reviewer with comments in the margins, text highlighted in yellow and sticky notes floating in the middle of your text. Before you send that document on to a client, a printer or an archive, you usually want all of that feedback gone, so the file reads as a clean, final version. Removing comments and annotations from a PDF is a quick job that runs entirely in your browser, and it is well worth doing before the marked-up copy leaves your hands. Here is how to clean a PDF of its comments, highlights and notes, and what to keep in mind as you do.

The two ways to clean a PDF

You can approach this two ways depending on what the file needs. Stripping annotations removes the notes, highlights and shapes entirely and produces a clean final document, which is right when the feedback was only for your own editing. Flattening, by contrast, merges the visible markup into the page so it can no longer be edited, deleted or toggled, which is useful when the annotations are part of a signed or approved copy. Most of the time you want to strip everything and send a document that looks as if it was only ever the final version.

Start from the cleanest copy you have

The result is only as clean as the source. If you have the original file that generated the reviewed PDF, export a fresh copy from that source and you avoid chasing annotations altogether. If the only copy you have is the marked-up file, the next best route is to work on that PDF directly. Keep your final file separate from the reviewed one, so you never accidentally send the version that still carries the comments.

Export clean pages and rebuild

When the PDF has annotations that sit directly on top of the content, the most reliable fix is to convert each page to an image with the PDF to image tool and rebuild the document with the images to PDF tool. Rendering the page to an image bakes the visible text and any leftover markup into one flat picture, which removes anything that was an overlay. It is heavier than a text PDF, but it is the surest guarantee that no comment, highlight or note survives structurally.

Crop and tidy the pages as you go

While you are rebuilding, it is the moment to polish the file too. If leftover annotation boxes or margin notes leave awkward empty space, remove unused pages and rotate any page that is the wrong way round, and if edges are cluttered you can crop the file down to the useful content. A clean layout is part of making the finished PDF look final rather than edited, which matters whenever the document will be read by someone else.

Reuse the text if you only need the words

Sometimes you do not need the layout at all, just the words between the comments. If the marked-up file is only a review pass and you want the content under it, extract the text and rebuild a tidy HTML, Word or text version instead of carrying the annotated PDF any further. This is especially handy when the annotations buried the flow, because you regenerate a clean document from the actual text.

Prepare the final file and share it

Once your PDF is free of comments and highlights, finish the job properly. Compress it with the compress PDF tool if the images make it heavy, and protect the file with a password with the protect PDF tool when the content is confidential, such as an approved contract or a signed form. Stripped, tidy and then protected, the document you send looks final on purpose and stays that way for everyone who opens it.
