SDL Passolo is a specialised visual software localization tool developed to enable the translation of user interfaces.

The company PASS Engineering GmbH was founded as a medical analysis system provider in Bonn, Germany, in 1990 and it proved crucial to provide localized medical software.

It allows users to concentrate on the translation by accelerating the many technical aspects of software localization, and it is possible to work in a WYSIWYG (What You See Is What You Get) mode.

Should the length of a text string change as a result of the translation (i.e. become longer or shorter), any necessary layout modifications to dialogs and forms can be made directly within the application.

The application offers the tools required to localize all the elements contained in the software, including strings, menus, dialogs, bitmaps, and icons, without requiring access to the source text files or the development environment used for developing the software, as well as providing automatic test functions, interfaces to the major translation memories, and the option of working with all the major Windows formats as well as text files and tagged formats such as XML and HTML.
