Comparing top tools for HTML-to-PDF conversion

In a perfect world, converting HTML to PDF would be a simple, straightforward process to incorporate into your app design. And it can be if you have the right tool.

But not all conversion tools are created equal, and if your app needs the functionality to convert HTML to print-ready PDFs — for example, documents, reports, or invoices — using the wrong conversion tool can not only cause serious frustration for your development team and end users, but also cost your company time and money.

So, the question is: What, exactly, is the best HTML-to-PDF conversion tool?

This article will compare some of the top tools for HTML-to-PDF conversion and guide you in determining which tool is the right one for your business.

Why you need the right HTML-to-PDF conversion tool

First things first. Before jumping into the different conversion tool options, it’s important to understand why you need an HTML-to-PDF conversion tool to begin with.

HTML and PDF formats have major differences. For example, HTML uses a flow-based layout, which means the different elements can adjust based on different factors, like screen size and resolution. Meanwhile, PDFs have a fixed layout that displays the elements consistently across devices and platforms. Browsers render HTML in real time, while PDFs are prerendered, which is why you can view them offline.

The right tool converts the HTML format into the PDF format and maintains consistency through the conversion. But not all tools are created equal, and the wrong tool can cause a host of issues for your business, your engineers, and your end users.

• Lost time and money — Without the right conversion tool, your team could lose hours manually fixing conversion-related errors, like formatting issues. And the more time your team spends dealing with these issues, the higher your labor costs, which means that not only do your employees lose time, but your business loses budget.

• Lost patience — Not only will the wrong HTML-to-PDF conversion tool cost your team time and your business money, but having to spend their time and energy fixing mistakes — mistakes that could have been avoided with the right tool — can also make your team lose patience and lead to morale issues.

• Security and compliance issues — If your application deals with sensitive data, like customer credit cards or healthcare information, using an HTML-to-PDF conversion tool that doesn’t prioritize security and/or adhere to relevant privacy regulations (like HIPAA) could put you at risk of a breach.

On the flip side, choosing the right tool can offer a host of benefits, like increased efficiency, enhanced security and compliance, and major savings — time, cost, energy, and frustration — for your team and business.

How to choose the right tool for your business

While this post outlines a few HTML-to-PDF conversion tools to get your wheels turning, the platforms mentioned here don’t even scratch the surface of available HTML-to-PDF conversion tools on the market. With so many options available, the question is, how do you choose the right option for your team and for your business?

Here are some tips for evaluating HTML-to-PDF conversion tools and ultimately choosing the best tool for your developers, your end users, and your company.

Make a list of needs and compare those needs to the tool’s features

When it comes to choosing the “right” HTML-to-PDF conversion tool — or any tool, for that matter — there’s no one-size-fits-all solution. The right tool for you might not be the best choice for another company.

The first step to figuring out the right tool for you is defining what, exactly, you need that tool to do. Before you start the search for an HTML-to-PDF converter, make a list of all the features you’re looking for.

For example, take a look at your tech stack. In what framework does your team primarily work? Do you need support for multiple languages, like C# and Java? Understanding your current tech stack can help you choose a tool that will fit easily into that tech stack and help you avoid potential integration issues in the future.

Or, as another example, think about what you need from security and compliance. Do you handle medical or health-related data? Then you’ll need a tool that’s HIPAA-compliant. Want to mitigate risk and protect your data? Look for a tool that prioritizes security and offers SOC 2 compliance.

The point is, before you start looking at HTML-to-PDF conversion tools, it’s important to clearly define what you need from that tool and then choose accordingly.

Consider volume needs

The best tool for your organization is going to vary based on how many HTML-to-PDF conversions your application needs to perform. If you’re only converting a handful of documents on a regular basis, then you’ll probably be able to get by with a simple tool. But if you’re processing thousands of conversions (or are planning to in the future), you’ll want to look for a more robust solution that’s designed for high-volume performance and scalability.

Look at the big picture on pricing

Obviously, cost is an important factor when making business decisions, including with whatever HTML-to-PDF conversion tool you choose. But while it might be tempting to go with the most affordable option available, it’s important to remember that the price of a tool doesn’t always reflect its true cost, and going with the cheapest option might actually cost you more money down the road.

Why? Because often, the cheapest tool is also the least effective. And while you might be paying less per month or year than you would with other, more effective options, you’ll be losing money in other areas, e.g. developers needing to spend more time on troubleshooting, navigating the platform, or manually fixing errors (which can lead to increased labor costs), or on losing customers after a data breach.

The point is, when you’re evaluating tools, make sure you’re looking at the big picture on pricing and choosing an HTML-to-PDF conversion tool that’s effective and secure and works with your budget.

Try before you buy

Sometimes, the only way to know if an HTML-to-PDF converter is going to be right for your business is to actually try it out and, luckily, many conversion tools offer free trials or demo periods allowing you to “try before you buy.”

If there’s a tool you’re interested in, sign up for the free trial and get to work testing it out. For example, try converting complex documents to check for speed and accuracy, have your developers work with the code and give their insights on the integration process, or reach out to customer service with an issue and see how they respond.

Rolling up your sleeves and actually using the tool is the best way to know how it’s going to work with your business and team. If the tool you’re considering offers a free trial, taking advantage of it is a no-brainer.
