About Video Compressor
What is Video Compressor?
VidPackit is a browser-based video compression and format conversion tool that processes video and audio locally without server uploads.
What Video Compressor does
The tool uses WebCodecs and the File API to decode, compress, and re-encode video files directly inside desktop browsers. It allows users to reduce video file sizes using four defined compression levels, change resolution presets to 720p, 480p, or 360p, convert between formats including MP4, WebM, MOV, and MKV, and extract audio tracks into MP3, AAC, WAV, FLAC, or OGG.
Who Video Compressor is for
For creators, developers, and web users who want to compress or convert video files locally on their device without uploading files to remote servers.
How Video Compressor works
Users drop a video into the browser, select a compression level or target resolution, choose an output format, and encode locally on their device.
