What Is Video Compression?
Video compression reduces the size of a video file by encoding it with a more efficient codec or lower bitrate. This makes the file smaller and easier to share or upload, while ideally maintaining acceptable visual quality. Modern video compression algorithms are remarkably effective — a 500MB raw video can often be compressed to 50–100MB with minimal visible quality loss when watched on a screen.
When Do You Need to Compress a Video?
Video file sizes are a constant challenge. WhatsApp limits video messages to 16MB (and 64MB for some accounts). Many email services have a 25MB attachment limit. Online course platforms and university portals restrict uploaded video sizes. Video platforms like YouTube accept large files, but uploading smaller files is much faster. Sharing video clips in messaging apps, on social media, or through cloud storage services is much easier with smaller file sizes. Students recording presentations or project demonstrations may need to compress their video before submitting to their university's learning management system.

Quality Options Explained
The Low quality preset produces the smallest file size and is suitable for sharing previews or low-resolution copies. Details may be noticeably reduced, but the video remains watchable. Medium quality is the recommended setting for most use cases — it provides a good balance between size and quality, suitable for sharing on social media and messaging apps. High quality applies moderate compression while preserving as much visual fidelity as possible — ideal for archiving or professional sharing where quality matters.
