Using advanced document previewing features - easily hide digital signatures from the signed documents while generating the document preview.

What is CDR file format?

A CDR file is a vector graphics file created by CorelDraw, a popular graphic-design program. It stores a single image made up of vector graphics, text, and bitmap images. Vector graphics are made up of lines, shapes, and curves that are based on mathematical equations, and are used to create illustrations, logos, and other graphic designs. CDR files can contain important design elements including layers, color tables, effects, and objects. They are usually saved as compressed files, which helps to reduce file size. CDR files are frequently used by professional graphic artists, but they can also be used by amateur users to create custom logos and drawings. CDR files are not compatible with many other programs, so it is important to use CorelDraw to open them and make changes. Once a file is saved in a CDR format, other programs may not be able to open it. However, some programs may be able to import and export CDR files.
