How To Annotate a PDF:
1. Drop your PDF file in the box above 2. Click the Annotate PDF button 3. Pick a tool - highlighter, note, pen, shape or stamp 4. Mark up any page you need 5. Download your annotated PDFHighlight, Comment, Draw and Stamp
Everything you need to review a document sits in one toolbar: a highlighter for key passages, sticky notes for questions, a freehand pen and shapes for sketching, and stamps such as Approved or Draft. Change color and thickness as you go.
Edited In Your Browser
The annotation editor runs entirely in your browser, so your PDF is marked up on your own device instead of being processed on a conversion server. Files you upload are deleted automatically after two hours.
Real PDF Annotations, Not Flattened Pictures
Your marks are written into the downloaded file as genuine PDF annotations. Acrobat, Preview and any other standard reader will display them, and the text underneath stays selectable.
Free, With No Watermark
There is no account to create, no trial to start and nothing stamped across your pages. Annotate as many PDFs as you like and download every one of them clean.
Works On Any Device
Because the whole tool lives in the browser, it behaves the same on Windows, macOS, Linux, Android and iOS. There is nothing to install and nothing to keep updated.
Built For Reviews and Feedback
Mark up a proposal before you send it back, flag corrections on a proof, or leave notes on a form someone has to fill in. Save the annotated copy and share it like any other PDF.
