Bulk Certificate Generator
Turn a spreadsheet into up to 100 signed certificates, right in your browser
UntangleTools’ certificate generator turns one template and a spreadsheet into up to 100 personalized certificates in minutes, entirely inside your browser. Upload a blank certificate design, drag on fields for names, course titles, or dates, then import your recipient list from a CSV, Excel, or JSON file — or just type in a handful of rows by hand. Add a real signature by drawing it, uploading a scanned image, or typing it in a handwriting-style font. It’s built for teachers issuing course completions, HR teams closing out training programs, event organizers, and workshop hosts who need professional results without design software. Nothing ever leaves your device, so recipient data stays private.
- Up to 100 certificates per batch
- CSV · Excel (.xlsx) · JSON
- 100% browser-based — nothing uploaded
- Single PDF or ZIP export
How the certificate generator works
Five steps, no design software required.
- Step 1
Upload your certificate design
Drop in a blank certificate as a PNG, JPG, or PDF (up to 8MB, 10MB for PDF). This becomes the background every generated certificate is built on top of.
- Step 2
Place your fields
Add a text field for each piece of information you need — recipient name, course title, completion date — then drag it into position. Resize by dragging the corner handle; the font grows or shrinks to match.
- Step 3
Add a signature
Draw a signature in the built-in signature pad, upload a scanned signature image, or just type a name in one of the handwriting-style fonts. Drawn or uploaded signatures resize freely in both directions so they fit the space exactly.
- Step 4
Import your recipient data
Upload a CSV, Excel (.xlsx), or JSON file with one row per recipient — or switch to manual entry and type in a few rows directly if you only need a handful of certificates. Map each field to a column, or combine two columns (like First Name and Last Name) with a separator of your choice.
- Step 5
Preview and generate
Flip through a live preview of any row before committing to anything. Then generate everything as one combined PDF, or as a ZIP file with one individually named PDF per certificate.
Who uses a bulk certificate generator like this
Six real workflows the tool was actually built around.
Universities & coding bootcamps
Export a cohort roster from the registrar or LMS as a CSV, map it to Name and Program fields, and generate 40–100 completion certificates in one pass — each one signed by the program director.
Corporate training & HR teams
Turn a compliance-training spreadsheet into signed completion certificates for an entire department without opening Canva or Photoshop. HRIS exports drop straight in.
Webinar & event organizers
Export attendee emails from Zoom or Google Meet, add a Name field, and send every attendee a personalized certificate of participation the same day.
Online course creators
Selling a course outside a big platform? Generate polished completion certificates for every student who finishes, without paying for a separate certificate-maker subscription.
Nonprofits & community workshops
Recognize volunteer hours or workshop attendance with signed certificates, built from nothing more than a sign-in sheet turned into a spreadsheet.
Youth & recreational sports leagues
End-of-season participation certificates for every player on the roster — import the team list once, generate the whole league in minutes.
Frequently asked questions
Upload your blank certificate template, drag on the fields you need, then upload a CSV with one row per recipient. Map each column to a field — for example, a "Name" column to your name field — and generate up to 100 certificates in a single batch, either as one combined PDF or a ZIP of individual files.
Yes. The built-in signature pad lets you draw a signature with your mouse or finger, in any ink color. If you already have a scanned signature image, you can upload that instead — or skip drawing entirely and type a name in one of the handwriting-style fonts.
Yes — the entire tool runs in your browser. Your template, your spreadsheet, and every generated certificate are processed on your own device and never uploaded to a server, so recipient data never leaves your computer.
Up to 100 certificates per batch, whether your data comes from a CSV, Excel file, JSON file, or rows you type in manually. You can also generate just a single certificate if that's all you need.
Yes. Map more than one column to the same field — First Name and Last Name, for example — and choose how they're joined: a space, a dash, a comma, or a custom separator you type in yourself.
No design tool is required for the data side, but you do need a blank certificate image or PDF to start from — a plain background with a border, logo, and title works fine. You place the actual names, dates, and signatures directly in the generator.
Yes. Choose the ZIP export option and you'll get one individually named PDF per certificate — the filename is pulled from whichever field you choose, like the recipient's name — instead of a single multi-page file.
The signature panel includes several handwriting- and script-style fonts — including Dancing Script, Great Vibes, Alex Brush, and Caveat — alongside standard weights and sizes, so a typed name can look like an actual signature.
It's built mobile-first and works in a phone or tablet browser, though placing and resizing fields precisely is easier with more screen space. For a large batch, a laptop or desktop is more comfortable.
