MeetHandBrake.The open source video transcoder.

HandBrake is a free, open-source video transcoder for Mac, Windows, and Linux. It converts video files and supported source media into widely compatible modern formats, making it useful when a file is too large, a device cannot play it, or an existing library needs a more practical encoding.
Choose a source, begin with a preset that matches the intended device or quality target, then adjust only the settings that matter. HandBrake can batch related jobs in its queue, so a collection of files can be prepared without reconfiguring every export from the beginning.
Features
- Convert supported video sources and files into modern, widely supported formats.
- Start with built-in presets, then fine-tune video, audio, subtitle, filter, and output settings when needed.
- Encode with common containers and codecs, including options aimed at broad device and player compatibility.
- Queue multiple encoding jobs and process them without configuring every file from scratch.
- Crop, scale, deinterlace, denoise, and otherwise apply supported video filters during a conversion.
- Preserve or select audio tracks, subtitles, chapters, and other supported source information for the output.
Where it fits
HandBrake fits archival, media-server, sharing, and playback-compatibility workflows where the aim is to make a finished video more usable. It is particularly valuable for turning a large master or awkward source format into an intentionally chosen delivery file.
It does not replace an editor for cutting a story, mixing audio, or designing titles. Keep a clear record of the source and export settings so a good result can be reproduced later.
Privacy and requirements
HandBrake is free and open source, processes media on the computer, and does not require an account. Encoding can use substantial CPU, GPU, storage, and battery, while protected or copy-restricted media may not be readable. Download only from the official project and keep the source file until the completed encode has been inspected.
Pricing
HandBrake is free and open source.
