Convert JSF to JS

Verified by Adam B.· reviewed by FE Editorial ·updated Jun 22, 2026
QUICK ANSWER
Is it possible to convert JSF to JS?
Yes - JSF converts to JS.

Rename the file from .jsf to .js in File Explorer, Finder, or the terminal - the file content is not changed. After renaming, VS Code and Notepad++ apply full JavaScript syntax highlighting automatically. Note that the script still calls Fireworks-specific APIs and will not run outside Adobe Fireworks.

Why convert JSF to JS?

The .jsf extension marks a file as a Fireworks command script, but the content is standard .js JavaScript. Renaming to .js makes the file recognisable to editors, linters, and code-search tools without altering any bytes inside the file.

Rename the file to .js using File Explorer or the terminal, then open it in VS Code - JavaScript syntax highlighting and linting activate automatically.

Quality & what to watch

  • No bytes inside the file are changed - renaming changes only the extension label.
  • The renamed .js still calls Fireworks-specific APIs (fw.*) and will not run in a browser, Node.js, or any runtime other than Adobe Fireworks (discontinued 2013).
  • To batch-rename on Windows PowerShell: Get-ChildItem *.jsf | Rename-Item -NewName { $_.Name -replace '\.jsf$', '.js' }.

Frequently asked questions

Does renaming .jsf to .js change the script's behaviour?
No - the file content is identical before and after; only the extension label changes.
Will the renamed .js file run in Node.js or a browser?
No - it calls Fireworks-specific methods (fw.*) that do not exist outside Adobe Fireworks.
Why would anyone rename .jsf to .js?
Mainly for tooling: editors, linters, and search tools treat .js files as JavaScript automatically, making archived Fireworks scripts easier to read and index.
