Add notes and highlights to PDF
Place genuine PDF sticky notes with editable message contents and colored highlight rectangles. Both are saved as native PDF annotations with appearance streams, without changing the underlying selectable text. They are not redaction.

How it works
- Choose your PDF file; it stays on your device.
- Choose Annotate PDF, type a note or set highlight dimensions, and click the page.
- Download the annotated PDF. Note display may vary among PDF viewers.
Beta release: features are introduced only after validation. General-purpose existing PDF text replacement, certified signatures, office document conversion and guaranteed irreversible redaction are not supported. The editor has narrowly limited experimental text replacement. Keep a backup of your originals.
