Hey everyone,
I’m looking for a safe way to turn HTML into PDFs in my C# project. Right now I use wkhtmltopdf, but I’m worried about security. It’s not great when users can add their own content or when there’s a lot of CSS.
Does anyone know a good alternative? I’d love something that:
- Works well with C# and .NET
- Doesn’t need extra programs to run
- Is safe to use with user content
- Can handle complex CSS
I’m okay with paid options if they’re reliable and have good support. What do you use in your projects? Any recommendations would be super helpful!
Thanks in advance for your suggestions!
For secure HTML to PDF conversion in C#, I’d recommend looking into Syncfusion’s PDF library. It’s a robust solution that integrates seamlessly with .NET projects and doesn’t require external dependencies. The library handles complex CSS well and offers built-in security features for dealing with user-generated content. While it’s a commercial product, their licensing is flexible and the comprehensive documentation plus responsive support make it worth considering. I’ve used it in several projects and found it reliable, especially when dealing with intricate layouts and dynamic content. Just keep in mind that there might be a slight performance hit with very large documents.
i’ve used iTextSharp in the past, it’s pretty solid for c# pdf generation. handles css decently and is secure for user content. bit of a learning curve tho. if you’re ok with paid options, check out aspose.pdf - heard good things about it. hope that helps!
I’ve had great success using IronPDF in my C# projects. It’s a native .NET library, so no external dependencies to worry about. The security aspect is solid - it handles user-generated content well, and I’ve never run into issues with malicious input.
What I really like is how it renders CSS accurately. I’ve thrown some pretty complex layouts at it, and it’s handled them like a champ. The API is straightforward too, which made integration a breeze.
One thing to note - while it’s not free, their licensing model is pretty flexible. I found the cost justified by the time it saved me in development and troubleshooting. Their support team is responsive if you hit any snags.
Just keep an eye on your memory usage if you’re processing a lot of docs simultaneously. Otherwise, it’s been a reliable workhorse for me.
