QuestPDF vs IronPDF

QuestPDF shines, but it's not built for the pros.

QuestPDF is simple and open-source; a good choice for small-scale projects.

But when your business grows, your PDF solution must match the speed: enterprise-grade HTML-to-PDF, full web standards compatibility, and expert technical support.

IronPDF accelerates the .NET development pipeline at any scale, eliminating technical debts that hold you back.

Let our product do the talking

Let's Get Straight to the Point

You're looking for a PDF library. Here's ours compared to QuestPDF.

Let's compare rendering HTML as a PDF in both IronPDF and QuestPDF:

Why?

QuestPDF excels at programmatic PDF creation, but HTML to PDF conversion? That's its Kryptonite. Oops!

IronPDF makes HTML to PDF conversion seamless, rendering any HTML string with precision using a built-in Google Chromium engine. It's straightforward, reliable, and built for developers who need results.

Speaks for itself, doesn't it? IronPDF might just be the perfect fit for your business needs.

We Love QuestPDF

Open-source is awesome. It’s free for non-commercial users, community-driven, and perfect for small projects. But when it comes to running a business… that’s where things get tricky:

Scalability Challenges: Open-source tools rely on community updates, which can lead to delays for critical features or fixes.
No Dedicated Support: Without Service Level Agreements (SLAs), issues can remain unresolved, causing downtime and lost revenue.
Feature Gaps: QuestPDF handles simple layouts well but lacks enterprise-ready features like HTML-to-PDF conversion, high-fidelity rendering, and compliance-grade outputs.

IRONPDF

This is where IronPDF shines. With 24/7 dedicated tech support, guaranteed SLAs, and monthly product updates, IronPDF ensures your business has the reliability and advanced features it needs to thrive.

From enterprises managing high-volume workflows to businesses requiring compliance-ready solutions, IronPDF delivers precision, scalability, and peace of mind because your time is too valuable for workarounds.

How IronPDF Works For You

Developers have shared their experiences with QuestPDF on Reddit, highlighting certain limitations. Here's how IronPDF offers solutions to these challenges:

Lack of PDF Form and Annotation Features

"Does it support editing existing and creating new annotations? Text boxes etc."

Answer - "This library is purely about generating PDF documents. At this moment I am not planning adding any modification features in the near future."

IronPDF Advantage offers comprehensive capabilities for creating and editing PDF forms and annotations, allowing developers to add text boxes, checkboxes, signatures, and other interactive elements to PDFs.

Absence of PDF/A Compliance for Archiving

"The QuestPDF docs and examples offer no working guidance on how to use QuestPDF in the cloud. The docs and examples all seem to assume we are writing desktop applications that run on Windows and read and write to the local filesystem."

Unlike QuestPDF, IronPDF provides clear, production-ready documentation for deploying in modern cloud environments including Docker, Azure, AWS Lambda, and Linux.

Dependency on SkiaSharp and Resulting Limitations

"The cost is that we need to deal with SkiaSharp limitations and their approach."

IronPDF operates independently of SkiaSharp, utilizing its own rendering engine to provide greater flexibility and avoid external limitations, resulting in more reliable PDF generation.

License Change Betrayal

"When I looked at this package a few months ago, it was FOSS. However, it now appears to be non-free. Can you please clarify: Have all 24 contributors consented to their work being re-licensed since they contributed?"

IronPDF offers clear, perpetual licensing with no hidden fees or contributor issues, what you buy is yours to use, forever.
