Our free PDF annotator uses pdf-lib to modify your documents entirely in your browser — no server, no account, no waiting.
Upload Your PDF
Drag & drop or click to select any PDF file. Encrypted documents are not supported — use our PDF Password Remover first.

Process & Download
Click "Process & Download PDF" and get your annotated document in seconds — completely private.
What You Can Do
Text Watermarks
Stamp "CONFIDENTIAL", "DRAFT", or any custom text on every page with adjustable opacity, size, colour, rotation, and placement (center, corner, or tiled).
Image Watermarks
Add a logo or background image to every page. Control opacity and placement — ideal for branding or protecting document ownership.
Text Annotations
Insert text labels on any page at precise coordinates. Choose font size, colour, and optionally add a white-out rectangle underneath for a clean overlay effect.
Image & Signature Overlays
Place PNG or JPG images — including transparent signatures — on specific pages. Scale the image as a percentage of page width.
Your PDFs Never Leave Your Device
Unlike most online PDF tools, our annotator processes everything locally. Your confidential documents are never uploaded to any server or transmitted over the internet.
