I need to convert a whole bunch of static SWFs to SVGs and I was hoping that there was some sort of command line tool I could use so I could script it with PowerShell. Does anyone know of such an application?

Sourceforge seems to have an SWF to SVG converter.


Or, the other way around


  • This, unfortunately is a web-based application. As the title of the question states, I need to automate this from a command-line, with no dependencies on an internet connection.

  • Sorry, I followed the link to the source code and missed the "Web converter tool" midway down the page. The svg2swf tool is command line so I stupidly assumed the swf2svg was too.

Research In Motion's development kit has a command line utility for this. You can get it in the dev kit here. The file is in the bin directory and is called swftosvg.exe.

swftosvg [-help] [-version] [-o 'outputfile'] [-d 'imagedir'] 'inputfile'.swf
display this help message
display product version
write the result of the conversion to 'outputfile' [default: 'inputfile'.svg]
write converted images to directory 'imagedir' [default: same directory as 'outputfile']


SWF is not necessarily static, where SVG usually is, there's no real way of converting SWF to SVG.

  • Actually, all of the SWFs I have are static.

    Also, I know it can be done, as I've done it in the past, but I can't remember the app I used because it was two years ago.

  • @blesh doesn't matter, they generally aren't... SWF and SVG are two very different kind of files...

    I've done it in the past. So yes, it can be done. In fact, there's a [web tool to do it][1], but what I'm looking for is a command line tool to do it. [1]: eprg.org/~sgp/swf2svg.html

  • @blesh I see... Another thing learned today :)

I found it myself.

The tool URL is here, it requires Java, but whatever.


I've checked a few links and they all return 404 or are redirects. Since this is a very old question.

I've found a way to do this using Python library pyswf on GitHub. The readme shows how to write a simple CLI that will convert SWF to SVG.

Copy-pasting it for reference:

from swf.movie import SWF
from swf.export import SVGExporter

# create a file object
file = open('path/to/swf', 'rb')

# load and parse the SWF
swf = SWF(file)

# create the SVG exporter
svg_exporter = SVGExporter()

# export!
svg = swf.export(svg_exporter)

# save the SVG
open('path/to/svg', 'wb').write(svg.read())

Note that PIP version was not working, as I'm writing this, with Python 3, I was needed to install pip2.7 to use the library.

If you have a problem installing pip2.7 here is a question on StackOverflow: how to use python2.7 pip instead of default pip
