Honest side-by-side comparisons to help you pick the right PDF generation tool for your project.
The classic command-line HTML-to-PDF tool, built on an old Qt WebKit engine. The project was archived in 2023 and no longer receives fixes or modern CSS support.
A Node.js library that drives headless Chromium. Rendering is excellent, but you own the browser lifecycle, the infrastructure, and every fix that comes with running Chrome at scale.
A programmatic Node.js library for building PDFs primitive by primitive. Powerful when you need full control, painful when a stakeholder wants to move a logo two pixels.
A mature Python library for programmatic PDFs, widely used in finance and government. Layouts live in Python code, which is robust but leaves designers out of the loop.
A well-regarded Python library for HTML-to-PDF with strong CSS Paged Media support. Actively maintained, but there's no hosted API, no editor, and no no-code integration layer.
The gold-standard CSS-to-PDF engine for book-quality print output, loved by publishers. Licenses start around $3,800 per production server plus annual maintenance, before any hosting costs.
A self-hosted Docker API that converts HTML, Markdown, and Office documents to PDF using headless Chromium and LibreOffice. Actively maintained, MIT-licensed, and free to run on your own infrastructure.
A developer-friendly HTML-to-PDF API built on the Prince engine, with strong typesetting, PDF/A, and PDF/UA support. Paid plans start at $15/mo for 125 documents.
A thin HTML-to-PDF API powered by headless Chromium, with webhooks, async callbacks, and S3/GCS output. Credits-based pricing — Boost plan at $24/mo for 2,500 credits.
A template-based PDF API built in France, using Liquid for data binding. Paid plans start at €5/mo for 300 documents, with webhooks and integrations for Zapier, Make, and n8n.
The developer API arm of iLovePDF — a broad PDF suite covering merge, split, compress, OCR, sign, and HTML-to-PDF conversion. Credit-based pricing with a generous free tier (~250 HTML PDFs/mo).
A peer-level PDF API with a drag-and-drop designer, JavaScript expressions and fillable forms. SOC 2 Type II audited and offers regional data processing in US, EU, Singapore and Australia. Paid plans start at $29/mo for 1,200 PDFs.
A close peer-level API that generates both PDFs and images from Jinja2 templates, with a WYSIWYG editor and a first-class image product. SOC 2 Type II audited with regional endpoints in US, EU, Singapore and Australia. Paid PDF plans start at $24/mo for 3,000 PDFs.
