KeePass KdbpFile format
A plugin to allow Import and Export in Fast KDBP format
*** NOTE: Not compatible with KeePass 2.35 or greater *** This is a plugin to KeePass <http://www.KeePass.info> to allow import and export of a new file format called KDBP. This contains 100% of the data in a standard kdbx file, and is encrypted using exactly the same compression, cryptography and integrity code. The difference is that inside the encrypted container, rather than XML, is a binary format serialized using Protocol Buffers. This has the advantage of being smaller and faster than XML, and is therefore particularly suitable for use with mobile versions of KeePass, such as Keepass2Android <http://keepass2android.codeplex.com/>. ... -

EJCCMTools
Generation of EJCCM files from SAM/BAM files
EJCCMTools is a Java software package for compression of SAM or BAM files, performing subsequent gene or transcript expression profiling and visualizing gene read coverage profiles. This novel compression scheme reduces file size by a factor of 214 compared to BAM files while keeping the full ability to analyze and visualize gene and isoform expression levels. As a result of the compression EJCCM files are generated. -

DNAcompact
Genome compression algorithm with/without reference (Linux/Windows)
...The proposed method without a reference led to bit rates of 1.720 and 1.838 bits per base for bacteria and yeast, which are approximately 3.7% and 2.6% better than the state-of-the-art algorithm. Regarding performance with reference, we tested on the first Korean personal genome sequence data set, and the proposed method demonstrated a 189-fold compression rate, reducing the raw file size from 2986.8 MB to 15.8 MB. -

UglifyJS
JavaScript parser library for NodeJS
...Its parser converts JavaScript into an abstract syntax tree that can be inspected or manipulated programmatically. The code generator can rebuild readable JavaScript or remove unnecessary whitespace to reduce file size. Its mangler shortens variable names while accounting for scope, globals, eval calls, and with statements. Compression routines simplify expressions, combine declarations, transform conditionals, and remove unreachable code. The package also includes a command-line interface and remains primarily a legacy version superseded by the rewritten UglifyJS2 project. -

bmp2rle
Encode bitmap(bmp) file with run-length encoding
...Try this project, I hope it can make a banlance between caculation and bandwidth. But first of all, you should know that the compression ratio of RLE is highly depend on the bitmap file data, the ratio can larger than 1, only when the same color continuously repeats in one line, it will gain a smaller compression ratio. -

Parallel DPCM
C# Parallel implementation of DPCM alogrithm
An implementation of the DPCM algorithm for compressing and decompressing an avi video file. It shows the compression size, as it is saved in a txt file near the avi original file. The decompression results in another avi file, saved near the original file. If the width and height of the frames aren't a multiple of 16, they are completed with black pixels. The pixel macroblocks of 16x16 are generated on separate threads for each frame and they are replaced on frames at decompression sequentially. ...
