HandBrake Free & Open Source Video Converter

Yes, HandBrake is completely free and open-source software. You can download, use, and share it freely without any cost. HandBrake is licensed under GPLv2, and the source code is available on GitHub.

HandBrake supports almost all mainstream video formats as input, including MP4, MKV, AVI, MOV, WMV, FLV, etc. Output formats support MP4, MKV, and WebM containers. Video encoding supports H.264, H.265/HEVC, AV1, VP8, VP9, MPEG-4, and more.

In HandBrake, select the H.265/HEVC encoder for better compression ratios. Adjust the "Constant Quality" (RF) value - higher values mean smaller files but lower quality (recommended between 18-23). You can also choose slower presets for better compression efficiency.

HandBrake itself does not support ripping DVDs with CSS copy protection. It can only rip discs without copy protection. To handle encrypted DVDs, you need to use other tools to remove the protection first.

This depends on your settings. With appropriate encoding parameters (such as RF value 18-20), the converted video quality can be very close to the original. H.265 encoding produces smaller files at the same quality. We recommend testing with a small sample first.

In HandBrake's video encoder options, select an encoder with hardware acceleration, such as "H.264 (Intel Quick Sync)", "H.264 (NVIDIA NVENC)", or "H.265 (AMD VCE)". Make sure your graphics driver is updated to the latest version.

Conversion speed is affected by multiple factors: CPU performance, encoder selection, preset speed, video resolution, etc. Enabling hardware acceleration can significantly improve speed. Slower presets provide better compression but are slower. 4K video conversion requires stronger hardware.

Yes, HandBrake officially provides full English interface support. The default language is English. You can change the interface language in Preferences if needed.
