This compression enables the creation of smaller files that are easy to share over email or cloud storage. Additionally, ZRTF supports a wide range of text styles, font attributes, and paragraph formatting, providing users with flexibility in their document designs. ZRTF also includes support for multimedia objects, such as images and tables, allowing users to enhance their documents with visual elements.

Opening ZRTF Files Using Other Applications

ZRTF files can also be opened using other applications that support the format. Some popular applications include:
