HandBrake is a free, open-source tool for converting video files into smaller, more compatible formats
(like H.264, MP4 or HEVC, aka x265). Simply download the app, open your video file, choose a preset (e.g.,
"Fast 1080p30"), set your output destination, and click "Start Encode" to begin conversion. It supports
batch processing via the "Add to Queue" feature for converting multiple files at once.
