What ToolsOnDuty Certificate Maker is

ToolsOnDuty Certificate Maker is a browser-based tool for teachers preparing personalized certificates for students, individually or in batches. It offers classic, modern, and playful designs, with fields for school, award, and signature details. For a class, names can be pasted one per line or imported from a CSV or Excel roster with a Name column. Duplicate names are skipped, and each student receives a separate printable page. The pages can be downloaded together as a multi-page PDF or printed. Users can also save and restore a JSON backup, while drafts autosave in the browser. Certificate data is processed on the user's device and is not uploaded to a server; school data stays in that browser's local storage unless exported. Downloaded PDFs have no watermark. The Free plan costs nothing, is free forever, requires no sign-up, and has no usage limits. The product is available on the web and does not offer a free trial.
