Preview: this tool is being tested and is not listed yet.

Generate individual certificates from a list of recipients. References come from the certificate details, so a retry gives the same numbers, and duplicates are made only once.

Formats: CSV or Excel (.xlsx). JPG, PNG or WebP for logo and signature. Exports a ZIP of PDFs and a register.
Limits: Up to 5,000 rows. No online verification: certificates carry a visible reference, and no QR code is added, because no verification service is connected.
Your data: Processed in your browser. Nothing is uploaded. Your draft is saved on this device only.
