Convert JNLP to another file type
To convert JNLP launch files to another format, you need Java Web Start or other Web software.
Convert a file to JNLP
To convert other file formats to the "Java Application Launch File" file type, you need software like Java Web Start or a similar tool.
About JNLP files
The .jnlp file format is an XML configuration file used by Java Web Start to download and launch remote Java applications over a network. It acts as a shortcut, pointing to the actual executable code hosted on a server. Historically, these files were executed automatically by the javaws executable bundled with Oracle Java. The .jnlp format is severely outdated and presents massive challenges today. Oracle deprecated Java Web Start in Java 9 and completely removed it in Java 11. Furthermore, modern web browsers no longer support the NPAPI plugins required to launch them. Maintaining the old Java 8 Runtime Environment just to run these files exposes systems to critical security vulnerabilities. Users often find themselves unable to open the file at all. You cannot convert a .jnlp file directly into a compiled exe or app executable because the file contains only text instructions, not the actual application code. Instead, convert your .jnlp to txt or xml to safely read the source code. For application archiving, use an online tool to parse the file and extract the direct download links for the underlying jar files.
Convert.Guru analyzes your JNLP file, detects the exact format, and lets you read the text inside.
If you want to convert JNLP file to PDF, JAR, EXE, HTML, HTM, CSS, JS, PHP, ASP, ASPX, JSP or JSPX, you can use Java Web Start or similar software from the "Java Web Start Launcher" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to JNLP, try Java Web Start or another comparable tool in the "Java Web Start Launcher" category.
The JNLP Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our JNLP converter.
