Check our videoThe GZ file format is a widely used compression format that reduces file size using the DEFLATE algorithm, commonly associated with Unix and Linux systems. It is supported by tools like gzip, 7-Zip, and WinRAR, and is often used for compressing single files or combining with tar for multiple files. GZ files consist of a header, compressed data, and an optional footer, with features like CRC-32 checksums for data integrity and optional metadata for additional information.
JPEG 2000 Core Image File (JP2) is a highly efficient image format designed for high-quality still image compression, offering superior performance compared to traditional JPEG. It is widely supported by applications like Adobe Photoshop, GIMP, and IrfanView, as well as specialized tools such as Kakadu and OpenJPEG for encoding and decoding. The format uses wavelet-based compression, supports lossless and lossy compression, and includes advanced features like progressive decoding, region-of-interest coding, and metadata embedding for enhanced flexibility and scalability.
You can also convert GZ into many other file formats. Please see the complete list below.
