Annotate PDF online

Highlight passages, draw freehand notes, add text and shapes, and revise every annotation before saving your PDF.

Annotate PDF pages with a focused live toolkit

Use highlights for passages, freehand drawing for marks, shapes for callouts and text for comments. Annotations remain selectable and undoable rather than being committed immediately.

  1. Choose an annotation tool

    Select Highlight, Draw, Shape or Add text from the live toolbar.

  2. Mark the page

    Place the annotation, then move, resize, recolor, rotate or delete it.

  3. Review and share

    Navigate every page, undo mistakes and export a clean annotated PDF.

Common questions

Can PDF annotations be edited before download?

Yes. Added text, highlights, shapes and drawings remain editable throughout the current session.

Can I draw directly on a PDF?

Yes. Draw follows the pointer continuously and creates a selectable freehand annotation.

Are annotations uploaded to a server?

No. Supported editing and export operations run locally in the browser.
