Update (25/07/2016): Now also available, a similar tool that converts JavaScript links to a page (using the this.pageNum-property) to "real" go-to-page links that point to the same page number.
This tool allows you to select whether to convert links, fields or bookmarks. It looks like this:
Update: Now available are demo versions of both tools, which will process up to 3 files, 3 pages per file and 3 links per page. You can download them from here.
Using the tool you can convert links with a JavaScript action to launch a web-site (using the app.launchURL()-method) to "real" web-links that point to the same URL.
This can be handy because JavaScript code in Acrobat can not create this type of links, only links with JS-code.
These tools run independently of Acrobat and can process an entire folder of PDF files (and all sub-folders) in a single go.
If you have any questions regarding this tool, you can contact me directly.
