Use PDF Annotation tool to annotate, highlight, sign, organize, merge, and export PDFs while every file stays on your device.

Mark up a PDF without sending the document to a website. PDF Annotation is a private PDF annotation app for Chrome where you can write, draw, highlight, sign, arrange pages, and export the result. Use it to annotate PDF files while every document stays on your device. The extension needs no account or network access. ✅ What you can do ✓ Draw freehand notes with adjustable color and line width. ✓ Add text boxes in multiple fonts, sizes, and colors. ✓ Mark areas with rectangles, ellipses, lines, arrows, or a highlighter. ✓ Place PNG or JPEG images anywhere on a page. ✓ Draw a reusable signature that stays in your browser. ✓ Reorder, rotate, duplicate, or delete pages. ✓ Add a blank page or insert pages from another PDF. ✓ Undo and redo annotation changes on each page. ✓ Export the full document or only the selected page. 🔒 Keep document review on your device This PDF annotation software processes documents locally and works as an offline PDF tool. The extension has no host permissions and does not upload your contract, coursework, report, or signature to an online PDF annotator. That matters when a document calls for private PDF annotation. ✍️ Use the right markup for the job Add comments with movable text boxes, or add notes to PDF pages in any of the included fonts. Use the highlighter to highlight text in PDF documents, sketch with the pen, or point to a detail with an arrow. These PDF annotation tools have adjustable colors, stroke width, shape fills, fonts, and text sizes, so you can separate a quick proofread from a detailed document review. 📄 Organize pages before you export Drag page thumbnails into a new order, rotate a sideways scan, duplicate a page, remove one, or add a blank sheet for notes. You can also insert pages from another PDF, which is handy when several source files need to become one marked-up document. ⚙️ How PDF Annotation works 1️⃣ Click the extension icon and open or drop a PDF into the workspace. 2️⃣ Pick a tool from the toolbar, then place your annotation on the page. 3️⃣ Select an object to move, resize, rotate, recolor, or remove it. 4️⃣ Arrange pages in the sidebar and import another PDF if needed. 5️⃣ Export the complete PDF or save the selected page as a separate file. ❓ What is PDF annotation? PDF annotation means adding notes, highlights, drawings, shapes, images, or signatures over a PDF document. It supports review and study while leaving the source page visible beneath your markup. PDF editing is different: it changes the document's original text or structure. PDF Annotation focuses on markup and page organization, not rewriting existing PDF text. 👥 Who can benefit from PDF Annotation? ✓ Students can highlight readings, add study notes, and insert blank pages for longer explanations. ✓ Teachers can mark assignments with text, pen strokes, shapes, and arrows. ✓ Reviewers can proofread PDFs, flag layout issues, and return one exported document. ✓ Professionals can mark contracts, place a signature, combine supporting pages, and keep sensitive files on the device. ⭐ Why choose PDF Annotation? 🛡️ Local processing keeps files out of third-party upload queues. 🧰 A single toolbar covers drawing, text, shapes, highlighting, images, signatures, and object removal. 📑 Page controls handle common PDF organization tasks without a separate editor. ⌨️ Keyboard shortcuts speed up repeated markup, while per-page undo and redo make corrections easy. 📤 Export preserves the original page content and adds your visible annotations to a new PDF. 💡 Tips for better PDF markup ✓ Use one highlight color for facts and another for questions. A simple color rule makes long reviews easier to scan. ✓ Keep text notes short and place them beside the passage they discuss. ✓ Use whiteout only as a visual cover. It is not redaction, and the underlying PDF content may remain recoverable. ✓ Export a selected page when a colleague needs one excerpt instead of the entire document. ✓ Keep an untouched copy of important source documents before you begin. ❓ FAQ 🖊️ How do I annotate a PDF in Chrome? Open PDF Annotation, choose your file, and select a toolbar tool. Add text, drawings, shapes, highlights, images, or a signature, then export the marked-up PDF. 🔒 Does PDF Annotation upload my documents? No. PDF rendering, markup, page organization, and export run on your device. The extension requests no network or host permissions. ✍️ Can I sign PDF forms with it? You can draw a signature, store it in the current browser, and place it on a PDF page. The extension does not edit interactive form fields or apply certificate-based digital signatures. 🎯 Turn a static PDF into a document you can review, explain, sign, and reorganize. Open your next file in PDF Annotation and keep the whole workflow in Chrome.
