Does Pdfrender run JavaScript like PDFShift does?

No. Pdfrender renders with WeasyPrint, which executes no JavaScript and fetches nothing external. If your document only reaches its final state after client-side JavaScript runs, PDFShift's headless-Chrome rendering is the better fit.

Can Pdfrender render a live web page from a URL?

No — you POST the HTML itself. PDFShift accepts a URL. Pdfrender deliberately fetches no external resources, which is also why images and fonts must be inlined as data: URIs.

Which is cheaper, Pdfrender or PDFShift?

It depends on volume, and you should check PDFShift's current pricing rather than trust a comparison table. Pdfrender is flat, and one render costs one credit: 100 credits a month free, €20/month for 10,000 credits, €80/month for 100,000.

Pdfrender vs PDFShift

PDFShift is a hosted Chrome-based HTML-to-PDF API; Pdfrender is a WeasyPrint-based API with flat subscriptions and an MCP server. Honest comparison.

Last updated 2026-07-26

PDFShift	hosted HTML→PDF conversion API, headless-Chrome-based rendering, usage-based paid tiers
Pdfrender	hosted HTML→PDF API + MCP server, WeasyPrint (CSS Paged Media) rendering, free tier + two flat credit subscriptions

Both are hosted APIs that turn HTML into PDF over one POST request. The core difference is the rendering engine: PDFShift renders with headless Chrome, so a document looks the way a browser would print it and client-side JavaScript can run; Pdfrender renders with WeasyPrint, a dedicated HTML+CSS print engine implementing CSS Paged Media (@page margin boxes, page counters), and deliberately executes no JavaScript and fetches no external resources.

When PDFShift is the better fit

Your document only reaches its final state after client-side JavaScript runs (charts drawn in JS, SPA-rendered views).
You want to render existing live web pages by URL rather than submit HTML.
You need browser-exact fidelity to what Chrome shows.

When Pdfrender fits

Print-first documents — invoices, reports, letters — where CSS Paged Media headers/footers and page numbers matter (guide).
Predictable flat pricing in credits — one render costs one credit: 100 credits/month free, Essential €20/mo (10,000 credits) and Scale €80/mo (100,000 credits) — two SKUs, no usage surprises.
Agent workflows: a built-in MCP server so LLM agents render PDFs as a tool call.
A deliberately small attack surface: no JS execution, no external fetches — a design choice, not a limitation you pay to remove.

Create a free account — 100 credits a month, no card and no password — or use the browser tool with no signup at all.
