Can I switch certificate layouts without losing my typed recipient text?

Yes! Clicking between Classic Navy, Modern Teal, Emerald, Minimalist, or Ruby switches the vector background and automatically adapts text colors for contrast, keeping your recipient name, date, citations, and signatures intact.

Can I edit an existing certificate PDF or image without losing quality?

Yes. Select 'Upload Custom' in the Templates tab, select your PDF or image, and our local engine will render it with crystal-clear high fidelity. You can place signatures, names, stamps, and dates directly over it.

Is my recipient data, signatures, and certificates private?

100% private. The entire Certificate Editor operates completely inside your browser sandbox. None of your certificates, names, or signatures are uploaded to external servers.

How do I get high resolution for printing on parchment paper?

When exporting, choose 'Download PDF (Print A4 300 DPI)'. It scales the canvas to 3000px resolution, ensuring razor-sharp borders and crisp typography for physical certificate parchment paper.

About the Certificate Editor

Creating professional certificates for students, employees, or event attendees requires flexible template editing without expensive software.

Use the Certificate Editor when you need to design, customize, or bulk-edit achievement certificates, diplomas, or course completion awards using any local file template path.

How Client-Side Processing Works

The browser-based application reads templates and user content in-memory. The engine uses Fabric.js client-side canvas rendering to support custom background images, text field editing, drawing paths/signatures, drag-and-drop alignment, and outputs high-quality PDFs or images securely.

Privacy Guarantee:Unlike traditional web services that upload your personal documents, images, or configuration files to third-party cloud servers, Singulariti executes all processing in your web browser's volatile memory. No files are transferred over the network, ensuring complete confidentiality.
