Ultimate Free Online Stamp Maker & PDF Stamper
Professional digital stamping made simple, secure, and accessible for everyone. Design, customize, and apply your official stamps in seconds.
100% Client-Side Privacy
Unlike other online PDF tools, we never upload your documents to a server. All processing—including rendering your PDF and applying the stamp—happens locally in your browser. Your sensitive business documents never leave your computer.
Professional Customization
Our generator isn't just a simple text-to-image tool. You can adjust border thickness, ink opacity, font styles, and even add a "distress" effect to make your digital stamp look like it was applied with a real rubber stamp and ink pad.
Multi-Format Support
Whether you have a contract in PDF format, an invoice as a JPG, or a receipt as a PNG, our tool handles it all. You can even stamp multiple pages of a PDF document with different positions for each page.
The Importance of Digital Stamps in Modern Business
In today's fast-paced digital world, physical rubber stamps are becoming a thing of the past. However, the need for official "Approved," "Paid," or "Confidential" markings remains. A digital stamp provides a professional touch to your electronic documents, making them look official and organized.
How to Use Our Online Stamp Generator
Getting started is easy. First, use our custom stamp designer to select your preferred shape. Circular stamps are traditional for official seals, while rectangular stamps are perfect for address labels or business titles. Once you've chosen a shape, customize the text. You can add your company name, a date, or a unique reference number.
After designing your stamp, simply click "Confirm & Proceed." You'll be asked to upload the document you wish to stamp. Since our tool uses PDF.js and PDF-lib technology, the file stays on your device. You can then drag the stamp to the exact location you need, rotate it for a more "hand-stamped" look, and resize it to fit the space perfectly.
Common Use Cases for Digital Stamps
- Accounting & Invoicing: Mark invoices as "PAID" or "DUE" with a bright red stamp to keep your records clear.
- Legal & Compliance: Add "CERTIFIED TRUE COPY" or "AUTHORIZED SIGNATURE" to legal documents before emailing them.
- Internal Office Use: Label documents as "CONFIDENTIAL," "DRAFT," or "INTERNAL ONLY" to ensure proper handling by your team.
- Creative Branding: Use a custom logo stamp to watermark your design work or photography before sharing it with clients.
Is an Online Stamp Legal?
In many jurisdictions, a digital stamp carries the same weight as a physical one for internal business processes. While some formal government or property documents still require "wet ink," the vast majority of day-to-day business correspondence is perfectly suited for digital stamping. Our tool helps you maintain a professional standard without the cost of physical supplies.
