Automate Certificate & Award Generation

Design a certificate template once in the visual editor. RenderStack fills in each recipient's name, date, course, and achievement — generating pixel-perfect certificates at any scale.

Why Manual Certificate Creation Doesn't Scale

Online courses, conferences, and training programs need to issue certificates to hundreds or thousands of participants. Manually creating each certificate in Canva, Photoshop, or Google Slides is painfully slow, error-prone, and impossible to automate. Even batch tools often produce inconsistent results — names get truncated, dates are formatted wrong, and branding drifts. You need a system that produces deterministic, pixel-perfect certificates from structured data.
Before RenderStack
  • Hours spent filling in names manually
  • Inconsistent formatting across certificates
  • Error-prone copy-paste workflows
  • No way to regenerate or update issued certs
  • Manual PDF export and distribution
With RenderStack
  • API call per recipient, instant generation
  • Pixel-perfect consistency every time
  • Zero manual data entry
  • Regenerate any certificate on demand
  • PNG, JPEG, or PDF output automatically

How It Works

1

Design Your Certificate

Create a beautiful certificate layout in the visual editor with your organization's branding, logos, borders, and signature areas.

2

Add Dynamic Fields

Mark the recipient name, date, course title, achievement level, and any other variable content as dynamic layers.

3

Generate via API

Call the render API with each recipient's data. RenderStack generates a unique certificate in PNG, JPEG, or PDF format in milliseconds.

Key Features for Certificate Generation

PDF Output

Generate multi-page PDF certificates ready for printing or digital distribution. Supports up to 50 pages per render.

QR Code Integration

Add verifiable QR codes that link to certificate verification pages. QR data is generated dynamically at render time.

Custom Fonts

Upload your organization's official fonts (TTF/OTF) for consistent branding across all generated certificates.

Fallback Chains

Handle missing data gracefully — if a middle name or title is missing, the layout adjusts automatically.

Generate a Certificate via API

bash
curl -X POST https://api.renderstack.io/v1/render/certificate-template \
  -H "Authorization: Bearer rs_master_xxx" \
  -H "Content-Type: application/json" \
  -d '{
    "overrides": {
      "recipientName": { "text": "Jane Smith" },
      "courseName": { "text": "Advanced Data Science" },
      "completionDate": { "text": "February 25, 2026" },
      "qrCode": { "src": "https://verify.example.com/cert/abc123" }
    },
    "format": "pdf"
  }'
