WHAT IS SWF?
Small Web Format
FutureWave Software, later Adobe Systems
SWF stands for Small Web Format and is owned by Adobe. Typically, SWFs are small files containing animated vector graphics data. It can be supplemented with text data and bitmaps. The SWF file type is often used to create banners, animations, and games. You may encounter some difficulties when trying to open SWFs, but browsers that support the Flash extension and the Adobe Flash Player software support playback of these files. Or you can try converting videos from SWF to a more standard format like MP4. To learn how to do this, read the information below.
The SWF file format is a binary multimedia format. Newer versions are capable of rendering text information, including bidirectional, and advanced scripts tagged with DefineFont4. Rich functionality provides support for JPEG images with alpha channel for areas of opacity and anti-aliasing filtering. Programmers can create files with SWF specifications using several Adobe programs, including Flash, Flash Builder, Adobe Animate, and After Effects.
