Why convert SWF to PNG?
Adobe Flash Player reached end-of-life on 31 December 2020 and every browser removed the plug-in. Exporting a PNG from an SWF preserves a logo, banner or title card from an old Flash file without needing Flash installed, and is useful for documentation and archiving.
How to convert SWF to PNG
SWFTools FREE
Run swfrender file.swf out.png in a terminal; for a multi-frame SWF, SWFTools writes a numbered sequence (out-0001.png, out-0002.png, ...).
Ruffle screenshot FREE
Open the .swf in the Ruffle desktop app, navigate to the frame you want, then use your OS screenshot shortcut and crop the result to PNG.
