About PDF Signer & Annotator

PDF Expert is the ultimate tool for signing and annotating PDF documents directly in your Chrome browser. Designed with a premium dark glassmorphism aesthetic, it provides a sleek and professional environment for all your document needs. Whether you need to sign a contract, fill out a form, highlight text, or redact sensitive information, PDF Expert has you covered. Key Features: Draw Freehand: Add notes or drawings smoothly with a responsive drawing tool. Add Shapes: Insert Rectangles (Boxes), Ovals, and Lines to highlight or diagram. Smart Text Boxes: Type directly onto the PDF. Text boxes automatically fit the text height and allow you to scale the font size dynamically. Sticky Notes: Add resizable yellow notes for comments and instructions. Insert Images: Place images (like stamps or logos) and resize them while maintaining aspect ratio. Persistent Signatures: Create a signature by typing (with cursive font) or drawing. It saves securely in your browser for future use. Move and resize it to fit perfectly. Search with Highlighting: Press Ctrl+F to open a floating search box. It finds text and draws a visual yellow highlight over the word on the canvas! Visual Redaction: Draw a solid black box over sensitive content to obscure it before sharing. Fast & Efficient: Uses lazy loading to render pages only when visible, making it incredibly fast even on 100+ page documents. Print Optimized: Includes a clean print layout that hides the app UI, printing only the document pages. Why Choose PDF Expert? Privacy First: All processing happens locally in your browser. Your documents are never uploaded to any server. Premium Experience: No clunky interfaces.
