What is a .BR file?
A .BR file is a type of compressed file that uses the Brotli compression algorithm. This algorithm was developed by Google in 2013 and is known for its efficiency in compressing data. The Brotli algorithm is particularly effective because it combines a modern variant of the LZ77 compression technique with Huffman coding, allowing it to compress files about 20% more effectively than its predecessor, the zopfli algorithm.
The .BR file extension is commonly used for compressing web page assets such as fonts (.WOFF), stylesheets (.CSS), JavaScript files (.JS), and vector graphics (.SVG). By using Brotli compression, these files become smaller in size, which helps web pages to load faster when accessed through internet browsers.
Popular web browsers like Google Chrome, Safari, Microsoft Edge, and Mozilla Firefox support the loading of .BR files directly, enhancing the speed and efficiency of web browsing.
If you need to open or manage .BR files, you can use several software programs. Some of the most common ones include: 1. **Google Brotli**: This is a command-line tool provided by Google for compressing and decompressing .BR files. 2. **PeaZip**: A free file archiver utility that supports a wide range of compressed file formats including Brotli. 3. **7-Zip-zstd**: An extended version of 7-Zip that supports additional compression algorithms including Brotli. 4. **Web-based tools like myl7 Brotli Encode/Decode Tool**: These are online tools that allow you to compress or decompress .BR files directly in your browser without the need to install any software.
Originally, Brotli was designed specifically for compressing WOFF font files, but its use has since expanded to include a variety of other web assets. It's worth noting that in the past, Brotli-compressed files used the .bro extension, but now the .BR extension is standard.
