About PDF Annotator
The PDF Annotator lets you mark up a PDF with text, highlights, freehand drawing, arrows, shapes and sticky notes, then export the annotated document. It's useful for reviewing contracts, giving feedback, or filling in scanned forms. All annotations are rendered and embedded in the browser, so the file is never uploaded.

Frequently Asked Questions
What annotation tools are included?
Text boxes, highlights, freehand drawing, arrows, shapes and sticky notes — enough to review, mark up or fill in most documents.
Are annotations part of the saved file?
Yes. Your markup is embedded into the exported PDF so it shows up in any PDF viewer.
Can I annotate a scanned document?
Yes. Annotations sit on top of the page, so scanned and image-based PDFs work the same as text PDFs.
Is my document uploaded?
No. Annotating and exporting both happen in your browser.
