Annotate a PDF — highlights, notes and ink, free
EditItAll annotates PDFs for free without uploading them: highlight and underline text, add sticky notes, text boxes, shapes and freehand ink in the browser-based editor, then export. Annotations are written into the file as real PDF objects, so they display correctly in Acrobat, Preview and other viewers.
How it works
- 1Open the PDF editor and load your PDF.
- 2Pick a tool — highlighter, underline, sticky note, text box, shape or ink — and mark up the document.
- 3Export — your annotations are baked in as standard PDF annotations that other viewers display.
Like every EditItAll tool, this runs entirely in your browser: the document is opened, edited and rebuilt on your own device, and nothing is uploaded. No account, no watermark, no page limits.
Frequently asked questions
Will my annotations show up in other PDF readers?+
Yes. They are exported as real PDF annotation objects with appearance streams, so Acrobat, Preview, browsers and other standards-compliant viewers render them — and they round-trip if you re-open the file here.
What annotation types are available?+
Seven: highlight, underline, free text boxes, sticky notes, rectangles, ellipses and freehand ink drawing.
Can I edit or remove an annotation later?+
Yes — annotations stay editable while you work, and if you re-open a PDF you exported here, they can be revised again.
Is my document uploaded for annotation?+
No. Everything happens locally in your browser — suitable for contracts and confidential papers.
