swftools are a unique set of tools but lack some user friendliness. They can't even iterate over provided objects:

Only one file allowed. You supplied at least two.

$ swfextract file.swf -i 1,2
warning! You should use the -P when extracting multiple objects

$ ls
file.swf  output.swf

$ swfextract file.swf -i 1,2 -P

$ ls
file.swf  output.swf

Use this one-liner

swfextract --outputformat "extract_%06d.%s" -a 1- file.swf

If you want to extract to a dir content, make that dir first:

mkdir content
swfextract --outputformat "content/extract_%06d.%s" -a 1- file.swf

Works fine.

See the docs.

Here is a bash script to automate it:

#!/bin/bash
find_ext=".swf"
out_ext=".jpg"

[ "$1" == "" ] && echo "Add type arguments from swfextract: -j -p -f -F -m -i" && exit 1 

for arg in $@; do
    for file in `find . -name "*$find_ext"`; do 
    ids="`swfextract $file | grep "\[$arg\]" | sed 's#^.*ID(s) ##g' |  sed 's#, # #g'`"
        for id in $ids; do
            swfextract "$file" $arg $id -o "${file}_${id}${out_ext}"
        done
    done
done

Don't forget to check the *_ext variables. Feel free to improve the script by adding extensions automatically.

  • I know this is very old, but I have a number of swf files each with a number of photos in them. I'm barely bash competent, so your code above is greek to me. I just created a bash script and put it in the folder with the swf files and when I run it is just spits out: Add type arguments from swfextract: -j -p -f -F -m -i

    A. Will the script above run through each swf and export each JPG? B. What am I doing wrong? I don't understand what "Add type arguments from swfextract" means or where to add them even if I did.

  • C. Also don't understand what you mean by "Don't forget to check the *_ext variables? – CRAIG Jul 05 '17 at 17:59
  • Try running this script with -j as the first argument, it's needed for catching IDs of objects (used in the line with grep). This way it should extract all JPEGs, meaning of other options should be on http://www.swftools.org/swfextract.html Maybe -p will work too and I'm not sure about others. – int_ua Jul 06 '17 at 17:16
  • Thanks so much for answering! Greatness! I am not following how I add in arguments? Like this?

    find_ext=".swf" out_ext=".jpg" $arg = "-P"

  • No, not in the script itself, when launching it, add the argument after its' name, something like this: ./bulk_swfextract.sh -j where bulk_swfextract.sh is the filename of the script. – int_ua Jul 06 '17 at 17:35

    Ahhhh. Totally got it. The combo of -p and -j extracted a ton of jpgs from a ton of swf files. Thanks so much!!!! – CRAIG Jul 06 '17 at 17:38
