What is compressing video files used for?

People compress videos to fit attachment limits on e-mail or Discord, upload faster on slow connections, and save storage space on phones and computers.

Does compressing a video always ruin quality?

Not necessarily. A moderate goal like Smaller file, good quality shrinks a file noticeably while keeping it clear for normal viewing.

What format do I get after compressing here?

The tool outputs a standard MP4 file with H.264 video and AAC audio that plays on phones, computers, and messaging apps.

What Does It Mean to Compress a Video?
