iSwiff

iSwiff

for macOS

Full Screen Flash outside the browser

Play Flash games, animations and movies without your web browser.

Enjoy full screen experience, uncluttered by browser toolbars and ads, when you find Flash you want to keep on your hard drive.

iSwiff uses Adobes's Flash web plugin (NPAPI edition) for playing the movies. The Flash plugin once came with Mac OS X, but you can also find the latest version on MacUpdate.

Play Flash files

Drag the Flash file onto iSwiff, or open it from the File menu.

Full Screen

Resize the window to the size you like, and choose "Full Screen" from the "Window" menu. After 5 seconds, the menu will hide.
To exit "full screen" move the mouse to the top of your screen and the menu will reappear. Or hit cmd-F.
You can also just hit cmd-Q to quit iSwiff.

Find Games

blinky Flash games are often designed to be played from your browser, but many are downloadable. Google is useful for finding Flash.

Double-clickable SWF files

Open With iSwiff If you select a SWF file in Finder and use "Get Info" (control-click the file), you can choose which application will open it. You can even let iSwiff become the default application for all Flash files.
