The SWF extension, pronounced "Swiff," is a creation of Macromedia and now owned by Adobe. SWFs are animations designed for use in Adobe's Flash software. The FLV extension, short for Flash Video, is a video format designed for compatibility with the Flash Internet plug-in. SWFs are typically animations, while FLVs are more often videos or pieces of interactive content. FLVs are playable in more players than SWFs, so converting between the formats will increase compatibility.
Navigate to mediaconverter.org in your favorite browser.
Click the "Upload a file" link on the homepage and choose the SWF you want to convert to FLV. The name of the file will be displayed in "Selected Files."
Choose "FLV" as the output extension. Click "Start" to initiate the conversion.
Click on the link that displays after the conversion is done to download the FLV.
Open Zamzar.com in your preferred web browser (see Resources).
Click the "Choose File" button and locate the SWF on your hard drive.
Select "FLV" in the drop-down menu. Indicate the email address to which you wish the file to be sent.
Click "Convert." Once Zamzar finishes, you'll receive a message with a link to your converted file.
