Systems and methods for rendering a secure document with a text selection capability. The methods comprise: performing first operations, by a computing device, to determine which objects of a source document are non-text objects; creating, by the computing device, an image file representing a graphic consisting of the non-text objects of the source document and a watermark merged together as a single image; drawing the graphic represented by the image file to a base document having a first file format different than a second file format of the source document; and drawing text objects to the base document from the source document so as to create the secure document with the text selection capability.
