Crossword Compiler can publish interactive puzzles for the web in just a few clicks. You can use these on your WordPress site, but will need to install a WordPress plugin. Then you can easily upload puzzles from files exported by Crossword Compiler, or import them from a puzzle page already uploaded to crossword.info (using the Web Publish button).

When you export the puzzle from Crossword Compiler, you must be using Crossword Compiler version 9/10 or higher (in version 9 you must select the HTML5 option, which is the default).
