Sign PDF Online Free — No Upload, 100% Private
Most PDF signing tools force you to upload your documents to their servers. That means your contracts, NDAs, and personal forms travel through the internet. DragKit is different. Draw your signature, place it on any page, and download — everything happens in your browser. No server. No upload. No risk.
✍️ Draw & Place Signature
Use your mouse or touchscreen to draw your signature. Place it anywhere on any page with pixel-perfect precision. Resize, reposition, and stamp. Your signature stays crisp in the final PDF.
📑 Merge Multiple PDFs
Need to combine documents before signing? DragKit lets you merge multiple PDF files into one, reorder pages, then sign the combined document — all in a single workflow.
🔒 Zero-Upload Privacy
Your PDFs never leave your device. There is no backend server. DragKit uses pdf-lib and PDF.js — JavaScript libraries that run entirely in your browser. Your contracts and personal documents stay private.
How It Works
- Drop your PDF onto the workspace — or click to browse files.
- Draw your signature on the canvas. Use your mouse, stylus, or finger on touch devices.
- Click "Place on PDF" — drag your signature to the exact position, resize it if needed.
- Click "Stamp" to fix the signature in place. Add more signatures if needed.
- Download your signed PDF. The signature is permanently embedded.

PDF Signing FAQ
Is this a legally valid signature?
DragKit creates a visual signature embedded in the PDF. For informal agreements, internal documents, and personal forms, this is widely accepted. For legally binding e-signatures that require audit trails and certificates, consider DocuSign or Adobe Sign.
Can I sign on my phone?
Yes! DragKit is fully responsive. On touchscreens, you can draw your signature with your finger. The signature pad works on iOS, Android, and tablets.
Can I add multiple signatures to one document?
Yes. After stamping one signature, you can draw a new one or reuse the same one. Place as many signatures as needed on different pages.
Is my PDF modified permanently?
Yes. When you click "Download Signed PDF", the signature is permanently embedded in the document using pdf-lib. The downloaded file is a new PDF with the signature baked in.
Can I merge PDFs without signing?
Yes! Switch to "Merge PDFs" mode. Drop multiple files, reorder them, and download a single combined PDF — no signature required.
