Understanding File Formats
Learn about different file types and when to use each format
Video Formats
MP4 (MPEG-4)
Most widely supported video format. Ideal for web streaming, social media, and mobile devices. Uses H.264 codec for excellent compression and quality balance.
WebM
Open-source format optimized for web. Uses VP8/VP9 codecs. Perfect for HTML5 video and offers better compression than MP4 at similar quality levels.
MOV (QuickTime)
Apple's format for high-quality video editing. Common in professional video production. Best converted to MP4 for broader compatibility.
Audio Formats
MP3 (MPEG Audio Layer 3)
Universal audio format. Excellent compression with good quality. Perfect for music players, podcasts, and streaming. Supported by virtually all devices.
FLAC (Free Lossless Audio Codec)
Lossless compression for audiophiles. Preserves original quality perfectly. Files are larger than MP3 but ideal for music archives and professional use.
WAV (Waveform Audio)
Uncompressed audio format. Highest quality but large file sizes. Used in professional audio production and editing workflows.
