Processing...
Drag a PDF that contains comments, highlights or other annotations onto the upload zone, or pick it from your device. The file is processed locally.
ZentoPDF walks every page, deletes the /Annots entries (sticky notes, highlights, drawings, free-text comments, stamps) and rewrites the page object tree without them.
Click download to get a brand-new PDF with no annotation layer left. The underlying content (text, images, forms) is untouched — only the mark-ups are gone.
Remove metadata, annotations, scripts, and more.
Make form fields and annotations non-editable by flattening them into the PDF.
Annotate, highlight, redact, comment, add shapes/images, search, and view PDFs.
Strip hidden data from your PDF.
Reduce the file size of your PDF documents while maintaining the best possible quality.
No. ZentoPDF removes only the /Annots layer (comments, highlights, sticky notes, drawings, free-text mark-ups). The original page content — text, images, vector drawings, form fields — is preserved unchanged.
No, regular interactive form fields (input boxes, checkboxes, signature fields) live in a different PDF structure and stay intact. Use our Flatten PDF tool if you also need to lock form fields into static content.
PDF highlights are usually implemented as transparent yellow rectangles inside the annotation layer. Removing annotations therefore also removes their visible highlight tint and any sticky notes attached to them.
No. Every operation runs locally in your browser using pdf-lib. Your original annotated PDF and the cleaned output never leave your device, which makes the tool safe for confidential review documents.
Yes — only the annotations are removed, the actual document text and structure remain intact, so the cleaned PDF is fully searchable, copyable and printable just like the original.
