Editing Deflate (section)

=== Encoder implementations ===
* [[PKZIP]]: the first implementation, originally done by [[Phil Katz]] as part of PKZip
* [[zlib]]: standard reference implementation adopted in many apps because of its open-source, permissive license. See {{section link|Zlib#Forks}} for higher-performance forks.
* [[Crypto++]]: contains a public-domain implementation in [[C++]] aimed at reducing potential [[Vulnerability (computing)|security vulnerabilities]]. The author, Wei Dai states "<cite>This code is less clever, but hopefully more understandable and maintainable [than zlib]</cite>".
* [[7-Zip]]: written by Igor Pavlov in [[C++]], this version is freely licensed and achieves higher compression than zlib at the expense of [[central processing unit]] (CPU) use. Has an option to use the Deflate64 storage format.
* [[PuTTY]] 'sshzlib.c': a standalone implementation under the [[MIT License]] by Simon Tatham, it has full decoding capability, but only supports static tree only creation
* libflate:<ref>{{Cite web |url=http://plan9.bell-labs.com/sources/plan9/sys/src/libflate/ |title=Plan 9 from Bell Labs's /n/sources/plan9/sys/src/libflate |website=plan9.bell-labs.com |publisher=Lucent Technologies |archive-date=2006-03-15 |archive-url=https://web.archive.org/web/20060315063934/http://plan9.bell-labs.com/sources/plan9/sys/src/libflate/ |url-status=dead}}</ref> part of [[Plan 9 from Bell Labs]], implements deflate compression
* [[Red Gate Software#HyperBac|Hyperbac]]: uses its own proprietary compression library (in C++ and assembly) with an option to implement the Deflate64 storage format
* [[Zopfli]]: C implementation under the [[Apache License]] by [[Google]]; achieves higher compression at the expense of CPU use. ZopfliPNG is a variant of Zopfli for use with [[Portable Network Graphics|PNG]] files.
* igzip: an encoder written in the [[x86 assembly language]], released by [[Intel]] under the [[MIT License]]. 3x faster than zlib -1. Useful for compressing genomic data.<ref>{{cite web |title=High Performance Deflate Compression with Optimizations for Genomic Data Sets |url=https://software.intel.com/en-us/articles/igzip-a-high-performance-deflate-compressor-with-optimizations-for-genomic-data |website=Intel Software |access-date=18 January 2020 |date=1 October 2019}}</ref>
* libdeflate:<ref>{{cite web |title=libdeflate |url=https://github.com/ebiggers/libdeflate |website=Heavily optimized library for DEFLATE/zlib/gzip compression and decompression}}</ref> a library for fast, whole-buffer Deflate-based compression and decompression. Libdeflate is heavily optimized, especially on x86 processors.

AdvanceCOMP uses the higher compression ratio versions of Deflate in 7-Zip, libdeflate, and Zopfli to enable recompression of [[gzip]], [[Portable Network Graphics|PNG]], [[multiple-image Network Graphics]] (MNG) and [[ZIP (file format)|ZIP]] files with the possibility of smaller file sizes than zlib is able to achieve at maximum settings.<ref>{{cite web |last1=Mazzoleni |first1=Andrea |date=21 February 2023 |title=amadvance/advancecomp |website=[[GitHub]] |url=https://github.com/amadvance/advancecomp/blob/fcf71a89265c78fc26243574dda3a872574a5c02/doc/advzip.txt}}</ref>
