2. Data compression - Wikipedia

   en.wikipedia.org/wiki/Data_compression

   Data compression. In information theory, data compression, source coding, [1] or bit-rate reduction is the process of encoding information using fewer bits than the original representation. [2] Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy.

3. Smallpdf.com - Wikipedia

   en.wikipedia.org/wiki/Smallpdf.com

   History. Smallpdf was founded in 2013 by Mathis Büchi, Lino Teuteberg, and Manuel Stofer while they were living abroad in Korea. The idea came from the need for their families to compress and send large documents via email. [4] The initial version of the site featured a standalone PDF compression tool. [5] Since then, the online platform has ...

4. Data compression ratio - Wikipedia

   en.wikipedia.org/wiki/Data_compression_ratio

   A compression ratio of at least 50:1 is needed to get 1080i video into a 20 Mbit/s MPEG transport stream. Uses. The data compression ratio can serve as a measure of the complexity of a data set or signal. In particular it is used to approximate the algorithmic complexity. It is also used to see how much of a file is able to be compressed ...

5. Weissman score - Wikipedia

   en.wikipedia.org/wiki/Weissman_score

   Weissman score. The Weissman score is a performance metric for lossless compression applications. It was developed by Tsachy Weissman, a professor at Stanford University, and Vinith Misra, a graduate student, at the request of producers for HBO's television series Silicon Valley, a television show about a fictional tech start-up working on a ...

6. bzip2 - Wikipedia

   en.wikipedia.org/wiki/Bzip2

   bzip2 is a free and open-source file compression program that uses the Burrows–Wheeler algorithm. It only compresses single files and is not a file archiver. It relies on separate external utilities for tasks such as handling multiple files, encryption, and archive-splitting. bzip2 was initially released in 1996 by Julian Seward.

7. Lossless compression - Wikipedia

   en.wikipedia.org/wiki/Lossless_compression

   Lossless compression is a class of data compression that allows the original data to be perfectly reconstructed from the compressed data with no loss of information. Lossless compression is possible because most real-world data exhibits statistical redundancy. [1] By contrast, lossy compression permits reconstruction only of an approximation of ...
