Comparing VeryPDF and WeasyPrint: Which Tool Provides More Accurate Webpage to PDF Rendering?
Every time I had to convert a complex webpage into a PDF, I ran into the same headache: layouts breaking, fonts missing, images not loading correctly, and worst of all the final PDF looking nothing like the original page. I know many developers and content managers feel this pain, especially when automating document workflows or generating reports directly from web content. It’s frustrating when your tool just doesn’t do justice to the original design, forcing you to waste hours tweaking or settling for subpar output.
That’s why I started exploring better solutions for webpage to PDF rendering, and today, I want to share my experience comparing two popular tools: VeryPDF Webpage to PDF Converter API for Developers and WeasyPrint. Spoiler alert if you care about accuracy, security, and speed, one clearly outperforms the other.
When I first stumbled on VeryPDF’s API, I was hunting for a robust, scalable HTML to PDF converter that could handle modern web technologies. As a developer, I needed something that:
-
Could render pages using a browser engine (not just basic HTML parsing)
-
Supported all modern CSS features and Javascript
-
Offered secure conversion, especially for sensitive client data
-
Integrated easily with my backend systems using REST APIs
VeryPDF’s tool ticks all these boxes and more. The API is based on Google Chrome’s rendering engine, so it faithfully reproduces everything you’d see on a real browser including tricky CSS layouts like flexbox and grid, custom fonts, animations, and even external JavaScript-driven content like charts or maps.
One of my favourite features is the ability to customise headers, footers, paper sizes, and inject CSS or JS before rendering. This saved me tons of time when creating branded reports for clients without needing post-processing.
In contrast, WeasyPrint, which is a popular open-source solution, uses its own rendering engine. While it does a decent job on simpler pages, I noticed several limitations:
-
It struggles with modern CSS3 features and responsive designs
-
Some web fonts didn’t render correctly, causing ugly fallbacks
-
Complex JavaScript-driven elements failed to appear in the final PDF
-
Limited options for adding headers, footers, or custom page sizes
Let me give you some concrete examples from my experience:
Why VeryPDF’s Advanced Rendering Engine Matters
I had to generate a PDF report from a client’s dashboard built on React with Tailwind CSS and some embedded D3.js charts. WeasyPrint couldn’t capture the dynamic charts properly, rendering blank spaces instead. VeryPDF’s API, on the other hand, rendered everything perfectly the charts looked crisp and identical to what I saw in Chrome.
Also, the flexibility to add headers and footers dynamically meant I could insert page numbers, timestamps, and custom logos on every page, all automated through API parameters.
Fast, Secure, and Scalable Automation
Converting dozens or hundreds of pages manually? Forget it. VeryPDF’s RESTful API allowed me to build a fully automated pipeline that converts webpages to PDF in under 2 seconds per document.
Plus, with 128-bit PDF encryption and access restrictions, I felt confident sending confidential content through the API without worrying about leaks.
VeryPDF also supports batch conversions with parallel requests perfect when generating bulk invoices or reports for clients without delays.
So, who exactly should consider using VeryPDF Webpage to PDF Converter API?
-
Developers and SaaS companies building apps that generate PDFs from live web content
-
Marketing teams automating branded reports or social media banner images
-
Healthcare and finance industries that require HIPAA-compliant, secure document handling
-
Content creators and publishers needing high-fidelity archive PDFs of complex articles or websites
-
Anyone frustrated by the inaccuracies of traditional converters like WeasyPrint or wkhtmltopdf

Why I’d Choose VeryPDF Over WeasyPrint for Webpage to PDF Rendering
From hands-on testing, VeryPDF’s output was consistently more accurate and visually faithful to the original web pages.
WeasyPrint might be suitable for simpler or static HTML reports, but when you’re dealing with modern, interactive websites or complex layouts, it falls short.
VeryPDF feels like it was built with real-world developer pain points in mind from security to scalability and high fidelity. The convenience of an API that just works means fewer headaches, less manual fixing, and faster delivery to clients.
