Adobe designed the Portable Document Format (PDF) to provide text and graphic formatting for documents. A second application is required to open PDF files. PDF files have become increasingly relevant in today's culture. Portable Document Format files are utilized in a range of businesses for invoicing and document production. Developers use the PDF format to help fulfill their clients' needs when creating documents. Creating PDFs has never been easier thanks to the libraries available today. In order to identify which library is the best on the market to employ in a project, we must consider elements such as constructing, reading, and converting.

In this article, we will compare the two most popular PDF converter libraries for .NET components; these two libraries are:

IronWebScraper
Winnovative

IronPDF and Winnovative are two libraries that may be used in your .NET applications to create, read, and update PDF files, whether on an online or desktop application. These two libraries can now be compared to see which is the best fit for our application. We will examine the features of the two libraries first, then compare their performance levels in converting and handling PDF files. Both libraries are supported by .NET frameworks.

IronPDF Features

IronPDF is a powerful PDF converter that can handle almost any task that a browser can handle. The .NET library for developers makes it easy to create, read, and manipulate PDF files. IronPDF uses the Chrome engine to convert HTML to PDF files. Among other web components, IronPDF supports HTML, ASPX, Razor HTML, and MVC View. IronPDF supports both ASP.NET Web applications and traditional Windows applications. IronPDF can also be used to make attractive PDF documents.

IronPDF allows us to create PDF files from HTML5, JavaScript, CSS, and pictures. In addition, headers and footers can be included in the files. We can read PDF files with ease thanks to IronPDF. IronPDF also includes a powerful HTML-to-PDF converter that can handle PDF files, as well as a robust PDF converting engine.

HTML, HTML5, ASPX, and Razor/MVC View are all examples of sources that can be used to create PDF files. Not only may HTML files be converted to PDF, but we can also convert image files to PDF.
IronWebScraper can help you create interactive PDF documents, fill out and submit interactive forms, merge and split PDF documents, extract text and images from PDF documents, search text in PDF documents, rasterize PDF pages to images, convert PDF to HTML, and print PDF documents.
IronWebScraper can generate a document from a URL. For login behind HTML login forms, it also allows the use of custom network login credentials, user agents, proxies, cookies, HTTP headers, and form variables.
IronWebScraper is an application that allows you to read and fill in PDF documents.
IronWebScraper is capable of extracting images from documents.
IronWebScraper allows us to add headers, footers, text, photos, bookmarks, watermarks, and more to documents.
IronWebScraper enables us to join and split pages in a new or existing document.
We can convert documents to PDF objects without using an Acrobat viewer.
It is possible to convert a CSS file to a PDF document.
CSS file media-type files can be converted into documents.

Winnovative Features

The Winnovative HTML-to-PDF Converter Library for .NET and .NET Core can be used to convert URLs, HTML strings, and streams to a PDF document, a raster image, or an SVG vector image in any .NET and .NET Core application, including ASP.NET, ASP.NET Core, and MVC websites, Windows Forms and WPF applications, and Azure Cloud Services.

You can use the HTML-to-PDF Converter for .NET as a general-purpose tool for converting web pages and HTML code to PDF and images, or you can use it as part of our .NET Reporting Toolkit to quickly create PDF reports directly from ASP.NET pages, and take advantage of ASP.NET controls' incredible capability.

HTML tags, HTML5 with CSS3, SVG and Web Fonts, page breaks, media type rules, repeating HTML tables, headers and footers, hierarchical bookmarks, tables of contents, fillable PDF forms, and HTML with page numbering in headers and footers are all supported by the converter.

The HTML-to-PDF Converter does not rely on any third-party software, and no special server settings are required for it to function. The same assembly works in both 32-bit and 64-bit environments, and copy server deployment is possible. The library works with the frameworks .NET 2.0, .NET 4.0, and later, as well as the runtimes .NET Core 2.1, .NET Core 3.0, and later.

Convert web pages, HTML strings, or in-memory PDF files.
Convert HTML strings and web pages to raster image formats.
CSS3, SVG, and Web Fonts-all supported HTML5 capabilities.
Convert HTML to PDF with SVG and Web Fonts.
During the conversion, you can enable or disable JavaScript.
Consolidate numerous PDF files into a single PDF.
Split a PDF file into numerous PDF files.

Edit existing PDF documents.
Add image elements to the PDF document that has been prepared.

Bootstrap and Modern CSS Framework Compatibility

Modern web applications increasingly rely on CSS frameworks like Bootstrap, Tailwind, and Foundation for rapid UI development. When generating PDFs from these applications, maintaining layout fidelity is crucial for professional document quality.

IronPDF: Native Bootstrap 5 Support

IronPDF's Chromium-based rendering engine delivers full support for modern CSS frameworks without configuration:

Bootstrap 5: Complete flexbox and CSS Grid support for all components
Bootstrap 4: Full compatibility with card decks, navigation bars, and responsive utilities
Tailwind CSS: All utility classes and responsive modifiers render correctly
CSS3 Features: Flexbox, Grid, transforms, animations, and custom properties
Web Fonts: Google Fonts, Font Awesome, and custom @font-face declarations

Proven with real-world examples: The Bootstrap homepage and official Bootstrap templates convert to PDF with pixel-perfect accuracy.

IRON VB CONVERTER ERROR developers@ironsoftware.com

$vbLabelText $csharpLabel

Output: A professional newsletter layout with Bootstrap's responsive grid, card components, and flexbox utilities—all accurately preserved in the PDF document.

Winnovative: Partial Bootstrap Support with Limitations

Winnovative's HTML-to-PDF converter uses a custom WebKit-based rendering engine with specific limitations for modern CSS frameworks:

HTML5 and CSS3: Advertised support but implementation gaps exist for advanced features
Flexbox Support: Partial implementation, complex Bootstrap 4/5 layouts may not render correctly
CSS Grid: Limited or no support for CSS Grid Layout specifications
Bootstrap 3: Generally works well with table-based layouts
Bootstrap 4/5: Flexbox-heavy components require testing and potential workarounds

According to developer feedback, Winnovative users commonly encounter:

Bootstrap navigation bars rendering with layout issues
Card components with flexbox not aligning correctly
Responsive grid breakpoints not being respected in PDF output
Need for custom CSS workarounds to achieve proper Bootstrap rendering

Impact on development: Applications built with Bootstrap 4+ may require significant CSS modifications or fallback to table-based layouts to achieve reliable PDF generation with Winnovative, increasing development and maintenance costs.

For comprehensive Bootstrap compatibility guidance, see the Bootstrap & Flexbox CSS Guide.

Let's take a look at how we can make a PDF document. ### IronPDFを使用する IronPDF enables us to quickly make a PDF document. It will create an HTML file and convert it to a PDF document from a URL. The built-in Chrome browser in IronPDF will assist us in downloading the HTML string. The following steps make it easy to create PDF documents. ```csharp // Create a ChromePdfRenderer instance IronPdf.ChromePdfRenderer Renderer = new IronPdf.ChromePdfRenderer(); // Convert a webpage into a PDF and save it var Pdf = Renderer.RenderUrlAsPdf("https://www.google.co.in/"); Pdf.SaveAs("result.pdf"); // Alternatively, chain the methods for brevity var Renderer = new IronPdf.ChromePdfRenderer() .RenderUrlAsPdf("https://www.google.co.in/") .SaveAs("result.pdf"); ``` In the example above, we have two options for converting the link into a document. Making a document via constructing an IronPDF object is one method, while making a `RenderUrlAsPdf` object is the other. The above implies that we can turn it into a document using `RenderUrlAsPdf`. Only the save location and the link must be provided. It takes 2.5 seconds to convert a PDF to a document. ### Using Winnovative With the help of the Winnovative library, we are able to transform a PDF document. The Winnovative library includes a built-in browser that will assist us in downloading HTML from a URL and converting it to a PDF. Below is the code to download and convert the HTML string into a PDF file: ```csharp // Create a HtmlToPdfConverter instance HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(); // Download HTML from URL and convert to PDF htmlToPdfConverter.ConvertUrlToFile("https://www.google.co.in/", "result1.pdf"); ``` First, we are creating an object for the `HtmlToPdfConverter` which allows us to use the list of options to convert the web URL into a PDF. `ConvertUrlToFile` is the method that helps us to download the source from the URL and convert it into a PDF file. We need to pass two parameters: the URL and PDF file location — both are mandatory. The time taken to convert the URL to a PDF document is 6.11 seconds. The image below is the comparison between IronPDF and Winnovative.

## Create PDF from HTML Strings Existing HTML pages or HTML code can be converted to PDF using both IronPDF and Winnovative. They will assist us in producing high-quality PDF documents. ### IronPDFを使用する We can transform HTML strings into PDF documents with the help of IronPDF. The following is an example of how to turn an HTML string into a document. It also has the ability to turn any HTML tag into a PDF document. ```csharp // Convert HTML string to a PDF document and save var Renderer = new IronPdf.ChromePdfRenderer() .RenderHtmlAsPdf("

Hello world!!

") .SaveAs("result.pdf"); ``` The accompanying example shows how to translate an HTML string with `RenderHtmlAsPdf`. In addition, the function that converts HTML to a string can take any number of HTML codes. Using the `SaveAs` function, we can save the document after getting the string. The process takes just two seconds to complete. ### Using Winnovative We can use the Winnovative library to convert an HTML string into a PDF document. It is simple and straightforward to use. The sample code for creating a PDF from an HTML string is shown below. ```csharp // Create a HtmlToPdfConverter instance HtmlToPdfConverter htmlToPdfConverter = new HtmlToPdfConverter(); // Convert HTML string to a PDF and save htmlToPdfConverter.ConvertHtmlToFile("

Hello world!!

", "", "result1.pdf"); ``` First, we are creating an object for the `HtmlToPdfConverter`, which allows us to use the list of options to convert the HTML into a PDF. `ConvertHtmlToFile` is the method that helps us to convert the HTML string into a PDF file. We should pass three parameters: the HTML string, the source URI (optional), and PDF file location. The HTML string and file location are mandatory parameters. The process took 3.6 seconds to complete. Below is the result of the comparison between IronPDF and Winnovative.

## Reading PDF Documents With the help of the IronPDF and Winnovative libraries, we can also [read PDF files](/examples/reading-pdf-text/). The documents can be readily converted to a text string. To extract the text, we can use one of two techniques. The first method returns all of the page data as a single string. The second technique is to get the data page by page, a method supported by both libraries. ### IronPDFを使用する The IronPDF program allows us to read existing PDF files and convert PDF pages into PDF objects. The following is an example of how to use IronPDF to read an existing PDF. The first approach to getting all the strings is shown below. ```csharp // Load a PDF document var pdfDocument = IronPdf.PdfDocument.FromFile("result.pdf"); // Extract all text from the PDF string allText = pdfDocument.ExtractAllText(); ``` The `FromFile` method is used to read PDFs from an existing file and transform it into PDF-document objects, as shown in the code above. We can read the text and images accessible on the PDF pages using this object. The object has a method called `ExtractAllText` that extracts all of the text from a PDF document into a string. ### Using Winnovative In addition, Winnovative assists us in reading existing PDF files. It also supports the two approaches mentioned above. The sample code for the first method of converting all of the PDF data into a single string is shown below. ```csharp // Load a document and count the number of pages var pdfDoc = new PdfToText.Document("result1.pdf"); PdfToTextConverter pdfToTextConverter = new PdfToTextConverter(); // Convert PDF pages to text string extractedText = pdfToTextConverter.ConvertToText("result1.pdf", 1, pdfDoc.Pages.Count); ``` In the above code, it shows that we are reading the existing document to convert it to objects to get the number of pages and other document-related information. After this, we use the `PdfToTextConverter` library and create an object for that library. By creating the object, we can access all the methods available. We are also using a method called `ConvertToText` which helps us to convert the PDF pages into text. There are three parameters we need to pass, which are filepath, start page, and end page. All the parameters are mandatory. Below is the result of the comparison between IronPDF and Winnovative.
