# Gallery demo

This sample application demonstrates DocuVieware as a document reader application alongside a document gallery containing various document formats, such as PDF, TIFF, and DOCX files, as well as JBIG2, JPEG, DICOM, SVG, and many others.

[Try demo](https://www.docuvieware-demo.com/gallery_demo.aspx)

Choose a document to display. Then annotate and browse it (for multipage documents), search for text, or use bookmark navigation.
