1
Download Adobe Flash from adobe.com. Adobe will allow you to download a 30-day free trial of Flash. Install this trial program on your computer.
2
Click on "File," then "Open" and browse to the .swf file you wish to convert.
3
Save the file as a new Flash (.fla) file.
4
Open the Flash file again. Scroll through to the .fla file frame-by-frame to find the frame(s), text and/or images that need editing.
5
Edit the frame(s). Then save the file again as a .fla file.
6
Open this file again. Choose "File," then "Export Movie."
7
Name the file "somefilename.swf." Note the location where you are storing the file and click "OK."
8
Open the HTML page where the new .swf file will be inserted. Insert the following code:
<object width="550" height="400">
<param name="movie" value="somefilename.swf">
<embed src="somefilename.swf" width="550" height="400">
</embed>
</object>
Tips & Warnings
It is always better to have the original Flash (.fla) version of the compacted .swf file for editing.
Flash Decompiler Trillix for Windows allows for editing both dynamic and static texts without Adobe Flash. However, it does not correctly recreate all Flash elements.
Note the use of both <embed> and <object> tags. Internet Explorer recognizes the <object> tag. Netscape only recognizes the <embed> tag.
Second Tipp
1
Download and launch latest version of Eltima Flash Decompiler (SWF Editor)
2
Add SWF file you want to edit to "My Tasks" list
3
After you added the file, switch to "Edit" tab, which is located on a ribbon of SWF files editor
4
Click the icon corresponding with the object you want to edit: Images, Sounds, Texts, Links, Colors or Lines
5
Replace currently selected element with a new one. Note, that if you are editing images, the size of a new image, which will replace the old one, should be nearly the same as the old one.
6
All changes you apply are displayed in main SWF file editor window.
7
Once you are done with editing the required objects save the changes and enjoy the result!
