Unbeaten processing speed provided by Google’s PDFium project allows Pdfium.Net SDK to deliver high-performance viewing, searching, printing and editing of PDF documents and filling PDF forms.
And thanks to excellent optimization, Pdfium.NET SDK works fluently even on low-end systems, consumes little resources and therefore powers up your applications with extreme user friendliness and responsiveness.
Rich rendering capabilities
Pdfium.NET PDF library supports the entire range of PDF rendering capabilities. Let your customers enjoy clear, sharp and accurate texts, objects, annotations and forms. Supply all functions and operations over PDF documents: viewing, printing, zooming in and out. Control the rendering process from your application or run it in the background for the best user experience.
Well documented SDK.
We have a rich documentation. This documentation aims to give beginners and advanced users an overview of what is possible with the Pdfium.Net SDK.
The documentation contains more than 2000 detailed, developer-targeted, MSDN styled topics, with conceptual overviews, definitions of terms, workarounds, and working code examples.

Support for asynchronous reading
Open large PDF documents and web documents fluently thanks to asynchronous reading. The idea is simple: once the first page is loaded, the reader displays it and continues loading the rest of the document in the background.
Why make your users wait? Apply asynchronous reading provided by Pdfium.NET library and start displaying contents of a PDF file almost instantly with the rest uploaded as the user reads.
Flexible page management
With Pdfium.NET SDK your apps can manipulate pages of a PDF document like a charm. Add or remove pages, merge or split PDF files, extract a range of pages and save as a new document with minimum coding required.
The extremely fast text processing engine of the library allows you to search, select, extract and fetch any given text from a PDF document in a blink. Use the text locally on at the server side to provide texts to search index services.
Easy page object editing
A page object is a feature that empowers developers with the ability to easily manipulate text, path, image, and other objects. You can add and delete PDF objects in a page and set specific attributes.
PDF forms made easy
Powerful action triggers
Imagine a trigger popping every time a specific action is performed and launching a custom event handler where the developer can configure document-level or page-level information to add to the document. Actions include opening, closing, saving or printing a PDF document.
