PDFShift alternative with predictable document-count pricing

The problem: file size can change your effective cost

PDFShift documents that each credit covers one conversion up to 5 MB. If a generated PDF exceeds 5 MB, the same document consumes additional credits. That can be reasonable for small documents, but image-heavy reports, catalogs, or exports can make usage harder to predict.

pdfkitt charges by document count. A larger PDF does not consume a second, third, or fourth credit because it crossed a file-size threshold.

A larger free tier for real evaluation

PDFShift's free plan includes 50 credits per month. pdfkitt's free tier is 1,000 PDFs/month, so you can test the full integration across development, staging, and early production traffic before paying.

That matters when HTML-to-PDF quality depends on real templates: invoices, dashboards, branded reports, customer exports, images, fonts, and print styles.

Side-by-side comparison

A simple managed API replacement

Both services are API-first. The migration path is straightforward: send HTML to https://api.pdfkitt.dev/v1/convert, pass your API key, and save the PDF response.

The practical difference is metering. pdfkitt keeps billing tied to the document, not the output size of that document.

Quick start

Use the same curl, Node.js, or Python snippets from the pdfkitt dashboard. Swap in your API key, send HTML, and write the PDF response to a file.

curl https://api.pdfkitt.dev/v1/convert \
  -H "Authorization: Bearer pdfk_live_YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{"html":"<h1>Hello, world!</h1>"}' \
  --output document.pdf

When PDFShift still makes sense

If you already use PDFShift, generate consistently small PDFs, and its credit model is predictable for your workload, there may be no urgent reason to switch.

pdfkitt is the better fit when generated file sizes vary, when you want a larger free tier, or when your team prefers a simple document-count model for HTML-to-PDF usage.
