Both APIs are REST-based and simple to integrate:

PDFShift Example

curl https://api.pdfshift.io/v3/convert/pdf \
  -u "api:YOUR_API_KEY" \
  -d '{"source": "https://example.com", "landscape": false}' \
  -o document.pdf

LightningPDF Example

curl https://lightningpdf.dev/api/v1/pdf/generate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{"html": "<html>...</html>", "format": "A4"}' \
  -o document.pdf

Both support:

  • Synchronous and asynchronous generation
  • Webhooks for completion notifications
  • Custom headers, footers, margins
  • Multiple page formats

Use Case Recommendations

Choose PDFShift if you:

  • Only need basic HTML-to-PDF conversion
  • Don't need templates or batch processing
  • Generate <10,000 documents/month
  • Want the absolute lowest per-document cost
  • Prefer a simple, focused API with no extras

Choose LightningPDF if you:

  • Generate invoices, receipts, or reports at scale
  • Want a visual template designer
  • Need batch processing (100+ PDFs per request)
  • Want sub-100ms generation for simple documents
  • Want a template library with pre-built layouts
  • Value advanced features over lowest possible cost

Template Designer Advantage

Here's where LightningPDF really shines:

PDFShift approach: Hand-code HTML, test, iterate, deploy

<html>
  <body>
    <h1>Invoice #{{invoice_number}}</h1>
    <table><!-- 50 lines of HTML --></table>
  </body>
</html>

LightningPDF approach: Use visual designer or marketplace template

  1. Browse template marketplace
  2. Select "Professional Invoice" template
  3. Customize colors/logo in designer
  4. Generate via API with JSON data

This saves hours of development time per template and makes PDF generation accessible to non-developers.

Batch Processing

PDFShift: No native batch support. You'd make 100 individual API calls to generate 100 PDFs.

LightningPDF: Single batch API call generates 1-1000 PDFs:

curl https://lightningpdf.dev/api/v1/pdf/batch \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -d '{
    "template_id": "invoice-v2",
    "data": [
      {"invoice_number": "INV-001", "amount": 100},
      {"invoice_number": "INV-002", "amount": 200}
    ]
  }'

Returns a ZIP archive with all PDFs. Perfect for monthly invoice runs or bulk report generation.

Data Handling

PDFShift: Cloud-only SaaS. No self-hosting option.

LightningPDF: Cloud API with zero data retention — your HTML and generated PDFs are not stored after the response is returned. A self-hosted deployment option is coming soon for enterprises with strict data residency requirements. Contact hello@lightningpdf.dev for early access.

Real-World Performance

Example: SaaS app generating 10,000 invoices/month

With PDFShift

  • Cost: $79/month (Medium plan)
  • Generation time: 2s/invoice × 10,000 = 5.5 hours total
  • Features: Basic HTML-to-PDF only

With LightningPDF

  • Cost: $29/month (Pro plan) - but includes templates + batch + fast path
  • Generation time: 0.08s/invoice × 10,000 = 13 minutes total (25x faster)
  • Features: Template designer, starter templates, batch API

The faster generation time means you can generate invoices synchronously in your web request instead of queuing background jobs.

LightningPDF is a complete PDF generation platform designed for modern SaaS applications. The template designer, marketplace, batch API, and dual-engine architecture make it the better choice for teams building PDF workflows at scale.
