These include ZIPX, RAR, APK, ISO, IMG, XPI and CAB, 8 of the formats can be used for compression. While not boasting tons of extra features apart from an image preview and viewer, it is a solid program with support for around 35 archive formats. The website also has a useful online unarchiver which can extract several different formats without needing software.īandizip is a program we’ve looked at in the past and it’s known for producing good compression ratios for the archives it creates. Pay attention to the installer as it pre-ticks an option to send statistical data to B1, download the standalone setup file to get the full installer and not the online downloader. Nearly 30 formats can be extracted including 7z and ZIPX. The program can only archive in ZIP or its own open source B1 format which uses LZMA compression. Max Compression used: EGG Priority on compress ratioī1 has versions for Windows, Mac, Linux and Android and calls itself a friendly and simple archiver. Useful options such as configuring an antivirus to scan manually, command line, span, merge and restore corrupted archives are all available. ALZip supports decompression of 40 archive formats such as 7z, RAR, CAB and ISO, and can compress to 8 different types that includes their own EGG format which offers generally better compression than ZIP. It’s also very useful to extract the contents of setup installers.ĪLZip used to be shareware but has been made available to use for free by the developer, the product key is shown on their website when you download the program. 7-Zip can compress to 7 formats and decompress to another 25 or so, including WIM, CAB, MSI, MBR and and VHD files. The stable version 9.20 has not been updated since 2010, but there are several newer alpha builds that keep development slowly moving. Being open source, 7z is now found in most other free and paid archiving applications. In each description is the result of whether the Omni.ja can be opened by the program and the setting used for the maximum compression tests.ħ-Zip is one of the most well known and popular archivers around due to the 7z archive format which compresses files into much smaller sizes than ZIP. We are going to test out the following 15 archivers, some free and some shareware. If you wish to go straight to the tests and results, they can be found on page 2 of this article. This is a valid optimized JAR file that should be supported by most archiver’s, but some detect it as corrupt and won’t open what is a legitimate archive. Finally we ran a quick test to see if each archiver can successfully open the Mozilla Firefox omni.ja file (English version). The second set of results is when using the best compression format the archiver has to offer. The first is to test (de)compressing a ZIP file as it’s still the most common and widely used format. To cover common real world scenarios, we’re going to perform 3 compress and 2 extract tests for each archiver, there are two main sets of results. Here we put 15 file archivers to the test to see which ones have the best compression rate plus the fastest speed. There are many claims made about who’s fastest or offers the best compression rate, but you will never know who’s right until they’ve been tried out. Many software archivers come with their own features but in the end what’s still important is the speed at which files can be compressed or extracted and the output size of the compressed file. ZIP archive compression is the only one which is natively supported out of the box by Windows, but like the copy function in Windows, there are better and faster alternatives.įor more serious compression needs, dedicated archiver software that can handle ZIP or other better formats may be required. Of course, there are many file compression formats around besides ZIP, others such as RAR and 7z are also very well known. Living in the internet age, it’s beneficial if a file can be compressed to half its size before you upload or download it, this can save bandwidth and time. Unlike JPG or MP3, ZIP is an archive format which allows you to store several files and also folders inside a single compressed ZIP file. One of the most popular and widely used file compression formats around today is ZIP which was developed by PKWare in 1989. Whether it’s game discs, Windows install discs, webpages, music, video, images, internet downloads or setup installers, most files are shrunk down from their original size to reduce the storage space they consume. Just about everything that gets stored electronically nowadays is compressed in some form or another.
