Additional information

PUB files are often used in web sites, and also in the process of generating templates for email messages. It is a proprietary format, supported by a limited number of applications – therefore, presenting results within a program may be a problem. A user who would like to display content a PUB file you have created, he would need to have the same application installed. However, such circumstances may be avoided, if following of these hints:

  1. After creating a document, you may export the content into the HTML format. Content of the document will be accessible via regular internet browser. What is important, is that a user will not be able to edit the project, but only to display it.
  2. If a project is based mainly on text, and it does not contain a lot of multimedia elements, a PUB file can be stored as a DOCX file. Text formatting will remain the same, however graphic or page layout may be not included.
  3. However, if an project editing option is necessary to be available, a person which receives a PUB file must install one of the programs which provide full support of this format.
