🔒 Why This Tool Is Safe
Unlike many online PDF editors that upload your file to remote servers, this tool processes everything locally in your browser using JavaScript. Your PDF never leaves your computer. This makes it ideal for sensitive documents like contracts, personal records, or confidential business files. The tool uses industry-standard libraries (PDF.js and jsPDF) to render and export PDFs right on your device.
💡 Use Cases
- Mark up drafts and proposals with feedback
- Highlight key clauses in contracts
- Add handwritten-style notes to presentations
- Annotate research papers and articles
- Fill out simple forms with text overlays
- Draw attention to specific chart elements
⚠️ Note: This tool converts PDF pages to images for annotation. The downloaded PDF will contain your annotations as flattened images. For advanced editing (like modifying existing text), a desktop PDF editor is recommended. This tool is perfect for quick markups, annotations, and visual edits.
