AI agents generate PDFs easily but choke on reading them — the file gets trapped, scanned pages return garbage, and raw page images burn the context window. Here's how a read_pdf MCP tool fixes it.
Yes, ChatGPT can emit a rough PDF through its code sandbox — but it can't reliably render designed HTML/CSS, hand the file to your app, or repeat the output. Here's what works and the durable fix.
wkhtmltopdf was archived and its ancient WebKit fork mangles modern CSS and carries unpatched CVEs — here are the three honest replacements and a concrete before/after migration.
ReportLab, WeasyPrint, or a hosted Chromium API — a practical, honest comparison of fidelity, ops burden, and cost for generating PDFs in Python, with runnable code for each.
Why bundling headless Chromium into a Vercel function causes cold starts, size-limit failures, and missing fonts — and how a Next.js Route Handler that calls a PDF API avoids all three.
Render a React component to a static HTML string with renderToStaticMarkup, then POST that HTML to a PDF API — with real Node/Next.js code and the styling gotchas that actually bite.
Puppeteer/Playwright, pdfkit/pdf-lib, or a hosted PDF API — a practical comparison of fidelity, ops burden, and serverless pain for generating PDFs from Node.js.
Wire Stripe's invoice.payment_succeeded webhook to Docweave so a branded invoice PDF is generated, stored, and emailed the moment payment clears — with real Node.js code and idempotency handling.
Running headless Chromium in a serverless function fails in ways that are hard to debug: bundle-size limits, cold starts, missing system libraries, and timeouts. Here's why, and the simplest way around it.
A buyer's guide to evaluating PDF generation APIs — pricing model, source formats, rendering fidelity, AI-agent support, idempotency, rate limits, and hosted vs self-host.
A step-by-step guide to building an HTML invoice template with placeholders, sending it template + JSON to Docweave's PDF API, and avoiding duplicate invoices with idempotency keys.
How to run high-volume PDF generation safely — concurrency limits, retries with idempotencyKey, failure handling, and why per-document pricing changes the math at scale.
Why @page CSS doesn't give you running headers in Chromium-rendered PDFs, and how to use headerTemplate/footerTemplate to add page numbers, titles, and dates correctly.
A practical guide to getting images, logos, and web fonts to render correctly in generated PDFs — data URIs vs hosted assets, @font-face gotchas, and how Docweave's Chromium renderer handles both.
Why webhooks and job queues redeliver the same event, how that causes duplicate PDFs and double-billing, and how to use idempotencyKey to make PDF generation safe to retry.
How to turn markdown files (READMEs, docs, changelogs) into PDFs programmatically: convert to HTML with a markdown library, then send that HTML to a PDF API. Includes a working Node example.
