Snappy
A fast compressor/decompressor
Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. Snappy is intended to be fast. On a single core of a Core i7 processor in 64-bit mode, it compresses at about 250 MB/sec or more and decompresses at about 500 MB/sec or more. (These numbers are for the slowest inputs in our benchmark suite; others are much faster.) In our tests, Snappy usually is faster than algorithms in the same class (e.g. LZO, LZF, QuickLZ, etc.) while achieving comparable compression ratios. -

Gemc
Prepare your CD images (BIN,CDI,NRG,CCD or similar) for compression
Gemc lets you prepare CD image files (such as BIN, CDI, NRG, CCD, or similar) so that they'll compress far better in programs such as WinRAR. HERE`S HOW TO USE IT: Run the CD image file (i.e. filename.bin) through GEMC to create an ECM file (i.e. filename.bin.ecm). Compress the ECM file (i.e. filename.bin.ecm) using your favorite compression program (i.e. 7Z,RAR,ZIP..). Back up, transmit via Internet, or whatever you normally do with CD images! When you want to burn the CD again, extract the original CD image from the ECM file. space saved depends on the number of sectors with unnecessary EDC/ECC data in them, which will depend on the specific type of CD -

Crunch
Insane(ly slow but wicked good) PNG image optimization
Crunch is an image compression tool for lossy PNG image file optimization. Using a combination of selective bit depth, color palette reduction and color type, as well as zopfli DEFLATE compression algorithm encoding that employs the pngquant and zopflipng PNG optimization tools, Crunch is effectively able to optimize and compress images with minimal decrease in image quality. While it may produce file size gains larger than those produced by lossless approaches, the impact on image quality is often imperceptible, and optimized file sizes are still significantly lower than the original. -

archiver
Easily create & extract archives, and compress & decompress files
Introducing Archiver 4.0 - a cross-platform, multi-format archive utility and Go library. A powerful and flexible library meets an elegant CLI in this generic replacement for several platform-specific or format-specific archive utilities. The core library APIs work pretty well but the command has not been implemented yet, nor have most automated tests. If you need the arc command, stick with v3 for now. Create and extract archive files. Walk or traverse into archive files. Extract only specific files from archives. Insert (append) into .tar files. Numerous archive and compression formats supported. Extensible (add more formats just by registering them) Cross-platform, static binary. Pure Go (no cgo). Multithreaded Gzip. Adjust compression levels. Automatically add compressed files to zip archives without re-compressing Open password-protected RAR archives. -

UglifyJS 3
JavaScript parser, mangler, compressor, beautifier toolkit
UglifyJS is a JavaScript compressor/minifier written in JavaScript. It also contains tools that allow one to automate working with JavaScript code. A parser which produces an abstract syntax tree (AST) from JavaScript code. A code generator which outputs JavaScript code from an AST, also providing the option to get a source map. A compressor (optimizer). it uses the transformer API to optimize an AST into a smaller one. A mangler, reduce names of local variables to (usually) single-letters. A scope analyzer, which is a tool that augments the AST with information about where variables are defined/referenced etc. A tree walker, a simple API allowing you to do something on every node in the AST. A tree transformer, another API intended to transform the tree. All the above utilities and APIs are defined in ~6500 lines of code (except for the effective generation of the source-map, which is handled by the source-map module). Compared to alternatives, UglifyJS is pretty small. -
