IronPdf 4.4.9

IronPDF - The C# PDF Library

IronPDF allows developers to create, edit and extract pdf content within .Net Applications & websites.

The Iron PDF library takes the frustration out of generating PDF documents by not relying on proprietary APIs. "Html-To-Pdf" renders pixel-perfect PDFs from open standard document types: HTML, JS, CSS, JPG, PNG, GIF, and SVG. In short, it uses skills that developers already posses.  

Key features include:
* "Html-To-Pdf" creates PDF files from HTML, CSS, JavaScript, and Images.
* "Url-To-Pdf" generates PDFs from existing html pages by simply providing their URL.
* "ASPX-To-Pdf" converts ASP.NET web forms directly into downloadable pdfs.
* "Image-To-PDF" creates PDF documents from image files.
* PDF to Image functionality can render PDF documents to image files.
* Extract text and images from existing PDFs.
* Create, Fill and read data from PDF forms.
* Merge, Split and Manipulate PDFs to edit PDF structure and content.  Add Page Numbers, Headers, Footers, Watermarks, Tables, Text and Image Assets.
* Edit, Stamp and Watermark PDF files with text, images and HTML
* Apply HTML or PDF backgrounds to PDF pages

IronPDF can be used within ASP.NET projects, MVC, Web Services, Console & Desktop Applications.

Requires .Net Framework 4.0 or above on the Windows platform. Compatible with cloud hosting services including Microsoft Azure.
