Sign & Stamp PDF: Add Signatures, Stamps & Logos to Any PDF

Add Signatures, Stamps & Logos to Any PDF — Free & Private

Need to sign a contract, stamp an invoice as "APPROVED", or place your company logo on every page of a proposal? Our Sign & Stamp PDF tool lets you drag and drop multiple images — signatures, rubber stamps, official seals, logos, initials — onto any page of your PDF document. Everything runs 100% in your browser. Your files are never uploaded to any server.

How to Sign and Stamp a PDF Online in 4 Steps

1. Upload your PDF: Click the upload area or drag your PDF file into the tool. Multi-page documents are fully supported — navigate between pages using the arrow buttons.
2. Add your images: Click "Add Image" to upload one or more overlay images. Use PNG files with transparent backgrounds for best results — especially for signatures and stamps.
3. Position & resize: Click any overlay to select it, then drag it to the exact position you need. Use the zoom controls to resize. Toggle the layers icon to place an image on every page (perfect for logos and watermarks).
4. Download: Click "Download Stamped PDF" to get your final document with all overlays flattened into the pages.

Create a Realistic Wet Ink Signature First

Want your signature to look hand-signed with authentic ink bleed and pen texture? Use our Wet Signature Generator to draw, type, or upload your signature with realistic wet ink effects. Download it as a transparent PNG, then come back here to place it on your PDF alongside stamps and logos.

Make It Look Printed & Scanned

After signing and stamping your PDF, give it the final touch of authenticity with our Make PDF Look Scanned tool. It adds realistic scanner noise, slight tilt, and grayscale effects — making your digitally signed document look like it was physically printed, signed with a real pen, stamped with a rubber stamp, and scanned back in.

Private & Secure Browser-Based Processing

Your documents are confidential. Unlike cloud-based PDF editors that upload your files to remote servers, EasyToolsNow processes everything locally using PDF.js and jsPDF. Your PDFs and images never leave your device. No accounts, no email collection, no data mining — just a fast, private tool that respects your privacy. Whether you are stamping a legal contract, a government form, or a confidential business proposal — your documents stay on your machine.
