Certificate Maker with Names List and Batch Printing

Certificate Maker is an offline app in one HTML file. Choose one of nine original certificate designs, change the wording, colours and signature lines, add your logo from your device, and keep a list of names with the award and reason for each. The batch printer puts one certificate on each page, numbers them one after another and remembers the next number, so the next batch carries on. Names and details can be typed, pasted from a CSV file or imported.

The problem it removes: Certificates for a class, a course or an event are made one by one in a word processor, the names are retyped, the border moves and nobody keeps count of the numbers. A reprint after a spelling mistake means finding the right file again.

What is inside:

• Nine original landscape designs on A4 or A5, with borders, ribbons and patterns drawn in the app
• A names list with award, reason and date for each person, importable from a CSV file
• Automatic numbering with a prefix and a first number, remembered after each batch
• Two signature lines with names and roles, and the issuing name from Settings
• Your own logo from your device, undo and redo, colour sets with a readability warning
• Print all in one go, one certificate per page at the exact page size
• Example data you can load in one click, a Start here guide and an Honest limits panel
• JSON backup and restore, CSV export, and CSV import with a check of every row before anything is added

Who it is for: A school, training centre, club, nursery or event organiser that hands out certificates in batches and wants them to look consistent and be numbered.

What it is NOT: It does not issue official or accredited certificates and makes no claim that any authority accepts them. It has no digital signatures, no verification page and no seal from any body. It does not include logos. Arabic text is untested. It is not legal, tax or accounting advice, it is not connected to any government system, bank or messaging service, and it does not file or send anything by itself. UAE e-invoicing is not part of it.

Verified by us: scripted tests in Chromium (88 checks through the real screens: adding, editing and deleting records in every table, required-field messages, backup then clear then restore, CSV export then import, keyboard order, print layouts rendered to PDF, no horizontal scrolling at 375 and 1280 pixels, no network requests) and no calculated fields to cross-check. Not tested: Safari and Firefox beyond what is stated here, and no real printer was used (print layouts were checked as PDF).
