The Offline PDF Signing Tool is a fully client-side, privacy-first browser utility that enables users to sign PDF documents completely offline after the page is loaded once. It is designed for freelancers, consultants, remote workers, students, legal professionals, and small business owners in Pakistan who need to add signatures to contracts, invoices, delivery receipts, NDAs, design approvals, or client handovers while traveling, during power outages, on slow internet, or in areas with no connectivity. The tool lets you upload a PDF, overlay a transparent PNG signature, drag it to the exact position on the page, and export a signed PDF — all processed locally without any server communication.
Upload your PDF (first page rendered for placement) and your signature PNG (transparent background strongly recommended). Drag the signature preview anywhere on the document canvas to position it precisely (e.g. over the signature line). The tool uses PDF.js to render the PDF page accurately and overlays the signature image so you can see the final appearance before exporting. Click "Download Signed PDF" to generate and save the modified file with your signature embedded as an image layer — preserving original PDF quality and compatibility with any viewer or email client. The signed PDF is ready for sharing via WhatsApp, email, USB, or local storage.
All rendering, placement, and export happen 100% in your browser — no files are uploaded, no data is sent anywhere, no internet required after initial load (CDN libraries cache locally). This makes it perfect for secure environments, remote locations, or situations where privacy and offline capability are essential. The interface is mobile-friendly with responsive canvas and touch-drag support, making it usable on phones/tablets when you receive a contract while out. It is especially practical in Pakistan’s freelance and remote-work ecosystem for quick signing without relying on cloud-based tools or desktop software.
Use it daily to sign PDFs professionally, maintain document control, reduce delays in client approvals, and work confidently even offline — free, secure, private, and always available in your browser. (Word count ≈ 302)
