PDF Toolkit API
PDFik is an asynchronous PDF generation API for developers: send a public URL or raw HTML, get back a job ID, and receive a signed webhook when the PDF is ready โ no polling loops required (polling endpoints exist too). Rendering runs on sandboxed headless Chromium, so modern CSS, web fonts and JavaScript-heavy pages come out pixel-accurate.
What makes it different:
"test": true to exercise the full pipeline โ statuses, webhooks, signatures, downloads โ without spending your quota.The Free plan includes 100 PDFs and 0.5 GB per month (card verified, never charged), and there is a no-account sandbox on the homepage to try a real render first. Paid plans start at $29/month (Starter, 5,000 PDFs / 10 GB) with a 99.5% SLA on all paid tiers.

DoczillaPDFik's answer
PDFik came from running page-to-PDF rendering in production the hard way: patched wkhtmltopdf builds, then a self-managed fleet of headless browsers. The takeaway: rendering belongs behind an async API with honest limits. PDFik is founder-built and bootstrapped, and in a category full of asterisks โ hidden credit math, vague retention โ it bets on published limits, signed webhooks, and guaranteed 24-hour deletion of generated documents.
Doczilla's answer:
At Doczilla, we embarked on a mission driven by necessity. Faced with the challenge of converting HTML into polished documents and images, we scoured the landscape for a solution that aligned perfectly with our needs. Surprisingly, we found none that matched our specific use case.
Our platform is our response to this gap. We've designed a fully managed API dedicated to simplifying the creation of PDFs and screenshots.
PDFik's answer
Many PDF APIs convert file size into "credits" that quietly eat into your document count; PDFik meters rendered PDFs and generated gigabytes separately and publishes every limit on the pricing page. Signed webhooks with automatic retries and a dead-letter queue ship on all plans โ a lost callback is an incident on our side, not silence on yours. The Free plan renders files up to 150 MB, while budget competitors typically cap free tiers at 1โ2.5 MB. And "test": true lets you integrate against the real pipeline โ statuses, webhooks, signatures โ without touching quota. Your card is verified, never charged.
PDFik's answer
Developers and engineering teams who generate documents from their backends โ invoices, receipts, reports, tickets โ and anyone tired of maintaining their own wkhtmltopdf builds or a self-managed Puppeteer/Chromium fleet. If you want page-to-PDF rendering to be an API call with a signed callback instead of a service you babysit, PDFik was built for you.
PDFik's answer
Rendering runs on sandboxed headless Chromium driven by Playwright โ one isolated browser context per job. The public API is Python/FastAPI; jobs flow through AWS SQS to autoscaled workers on EKS (ARM/Graviton), with PostgreSQL, Redis, and S3 behind them. The dashboard is Next.js/TypeScript, and the official SDKs ship in TypeScript, Python, and Java.
PDFik's answer
PDFik is async-first: submit a URL or raw HTML, get a job ID back, and an HMAC-signed webhook tells you when the PDF is ready โ on every plan, including Free. Billing runs on two published meters โ rendered PDFs and generated gigabytes, counted separately โ and downloads never debit your quota. Add to that a free test mode that exercises the full pipeline without burning quota, 150 MB files even on the Free plan, and guaranteed deletion of generated documents within 24 hours.
