FlexViewer is a document and report viewing UI control for displaying and embedding PDFs in your .NET applications. The .NET PDF viewer supports printing, export, thumbnails, rotate pages, search, and responsive layouts for mobile web applications. Load PDFs from files or streams. You can also use its internal PDF DocumentSource to work with PDF files in completely in C# or VB.NET code.

PDF documents with embedded fonts, such as CFF, TTF, OpenType, and Type1, can be opened without impacting the font style. It means the system font does not replace the original font.

You can search text in a PDF document once you open it in FlexViewer, or through code using simple methods to find each occurrence.

When exporting a PDF, you can add password protection. That's all there is to it!

Add input fields to your documents to create acroforms. Fields allow the end-user to edit the document through checkboxes, radio buttons, comboboxes, textboxes and signature fields.

Choose multiple levels of compression for high quality and small file size. Metafiles are parsed and converted into vector graphics, retaining the best possible resolution. Metafiles are ideal for adding charts or technical drawings to your document.

Encrypt your generated documents with separate passwords for owners and users. The user's access can be selectively restricted to enable only certain operations, like viewing, copying, printing, or editing the document.

Create long PDF documents with an outline structure displayed as bookmarks. The bookmarks make it easy to browse through a document's structure and find specific topics.

Attachments can contain any kind of file, including spreadsheets with detailed information that would clutter the main document, multimedia files with movies and sound, sample code, and other file types.

Through the .NET PDF generator, you can add annotations to PDF files that are created dynamically in code.
