ZIP Archive Format ZIP Converter
The ZIP format was created in the late 1980s as a way of compressing files for archiving or sharing. Files are ‘zipped’ up into a new folder, usually saving it into a smaller file size. ZIP uses lossless compression and is reversible, so you can ‘unzip’ the folders and extract files without any impact on quality. As each file is compressed separately during ‘zipping’, you can easily extract or add individual files to a ZIP folder.
ZIP files became more popular with the rise in email use, as it was a simple way to share multiple larger files. The ZIP format is also often used to make back-ups, quickly transfer files between devices, and to allow quicker downloads from websites. Previously, users needed additional software to create ZIP folders. Now most operating systems, including Windows and iOS, let you easily zip and unzip files yourself.
7Z Archive Format 7Z Converter
A 7z file is also known as a 7-Zip compressed file and was developed by Igor Pavlov. It was developed in the late 1990s before being finally released in 1999 and is a compressed archive which uses 7 different types of open source archive technology including LZMA compression which compresses at an estimated 1MB/s and decompresses at up to 20MB/s. 7z files are particularly popular because of how efficient they are. They can contain multiple directories, as well as files, all of which are compressed which means that they support files up to the size of 16,000 Petabytes. To open a 7z file users can use 7-Zip, WinZip for both Windows and MacOS and File Viewer Plus.
