Yes, Online Stamp Generator is 100% free forever. Unlike other websites (such as MyStampReady or Make-Stamp) that charge $2.50 to $5+ per download or lock high-resolution files behind paywalls, you can design, customize, and export unlimited high-resolution PNGs (up to 1200 DPI), pure vector SVGs, and print-ready PDFs without subscriptions, watermarks, or account registration.

An online stamp generator is a browser-based design tool that allows you to create custom rubber stamps, official company seals, notary marks, and document status badges without installing graphic design software. You can design round seals (38mm, 40mm, 42mm, 45mm, 50mm), rectangular endorsement stamps (APPROVED, PAID, RECEIVED, CONFIDENTIAL), triangular inspection marks, and vintage postal cancellation stamps.

Yes. You can design standard circular seals tailored for US Notary Public, UK Solicitors, corporate LLC verification, and official certification marks. You can customize outer rings, inner concentric borders, state or country jurisdictions, commission IDs, expiration dates, and insert emblems like the Scales of Justice, corporate crests, or stars.

Our stamp editor features an intelligent curved typography engine. When you select 'Bottom Arc', the text is automatically calculated along a counter-clockwise path so it renders right-side-up, reading naturally from left to right across the lower curve of the stamp instead of flipping upside-down.

Yes! Use our built-in Document Stamper tool (/pdf-stamper). Upload any PDF invoice, contract, or Microsoft Word (.docx) document, choose your stamp design created in the studio or a preset template, position and tilt it on any page, and download the stamped document instantly. All document processing happens 100% locally in your browser with zero server uploads.

In most international jurisdictions, digital stamps and electronic corporate seals are accepted for internal office approvals, invoices, receipts, bills of lading, and commercial agreements when used alongside valid electronic signatures. However, specific statutory filings or certified state notarizations may require registered physical embossing or qualified electronic signatures (QES) according to local regulations (such as eIDAS in the European Union or state notary statutes in the US).

You can download three professional formats: (1) Vector SVG: Infinite lossless scalability, perfect for digital signatures and laser engraving; (2) Transparent PNG: Rendered at 1x, 2x Retina, 4x (300 DPI print standard), and 6x (1200 DPI ultra-high definition); and (3) Print-calibrated PDF: Calibrated at exact 1:1 physical millimeter scale for immediate printing.

Standard circular seals range from 38mm (1.5") for compact notary seals, 40mm (1.57") for standard corporate LLC marks, to 45-50mm (1.77"-2.0") for government and academic crests. Standard rectangular office stamps (such as APPROVED, PAID, RECEIVED) typically measure 47x18mm (1.85x0.71") or 58x22mm (2.28x0.87"). You can consult our full Stamp Sizing Guide (/stamp-sizes) for detailed millimeter, inch, and pixel specs.

Yes! You can upload custom PNG, SVG, or JPG icons directly into the center layer of your stamp. Our editor allows you to adjust size, opacity, and automatically tint your uploaded monochrome logo to match the selected stamp ink color (Red, Blue, Black, Green, or Violet).

Yes. All stamp rendering, text calculations, image uploads, and PDF stamping execute 100% locally in your browser's memory using modern Web APIs. We do not store, view, or transmit your stamps or uploaded documents to any remote server.
