What ToolsOnDuty Certificate Maker is
ToolsOnDuty Certificate Maker is a free web tool for teachers creating 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 batch, the award text, date, and signatory are shared across certificates. Names can be pasted one per line or imported from a CSV or Excel roster with a Name column; duplicate names are skipped. The tool makes a separate printable page for each student and can download the results as one multi-page PDF. Users can also print certificates and save or restore a JSON backup. Drafts autosave in the browser. The product page says certificate data is processed on the user’s device and never uploaded to a server, while school data remains in that browser’s local storage unless exported. Downloaded PDFs have no watermark. Its Free plan costs nothing, is free forever, runs in the browser, requires no sign-up, and has no usage limits.
