    FLV

    FLV (Flash Video) is a video container format developed by Adobe and widely used by early online platforms such as YouTube (early years), Google Video, and Yahoo Video. Designed for web streaming via Flash Player, FLV delivered smooth playback with relatively small file sizes. However, as Flash technology has been discontinued, FLV now has limited compatibility with modern browsers and devices, making conversion to more common formats like MP4 or MP3 often necessary.

    MP3

    MP3

    MP3 is one of the most widely used audio file formats, known for its high compatibility and small file size. It uses lossy compression technology, reducing file size while maintaining acceptable audio quality, making it the preferred format for music downloads, podcast audio, and playback across various devices. On Windows, macOS, Android, and nearly all media players, MP3 remains a lightweight, universal, and almost ubiquitous audio format.
