pdfkitt vs API2PDF
API2PDF is flexible: it exposes several rendering engines and bills per request, which is attractive at high or spiky volume. pdfkitt takes the opposite stance — one managed Chromium pipeline and a flat monthly plan, so behavior and cost are predictable.
Side-by-side comparison
| API2PDF | pdfkitt | |
|---|---|---|
| Rendering engine | Multiple — Chrome, wkhtmltopdf, LibreOffice | Single managed Chromium (Playwright) |
| Pricing model | Pay-as-you-go, around $0.001 per PDF | Flat monthly plans with a free tier |
| Free tier | No standing free tier | 1,000 PDFs / month |
| Extra formats | Office document conversion | Focused on HTML to PDF |
| Surface area | Several engines to choose and reason about | One predictable rendering path |
When API2PDF is the better choice
API2PDF makes sense when you need its breadth — Office document conversion, a specific legacy engine like wkhtmltopdf, or pure pay-as-you-go billing for highly variable workloads where a monthly plan would sit idle.
pdfkitt is the better fit when you want one consistent Chromium renderer, predictable monthly pricing, and a real free tier to build against. Fewer engines to choose from means fewer surprises in how a given PDF comes out.
