GZipHelper
This nice post on the CodeGuru web site does Gzip compression to and from memory, instead of to and from files.
Braxio FreeZip
Advertises itself as the “The Best Free Zip Utility on the Net!” Free registration is optional, enables search utility which provides some payback.
JPEG 2000 Part 6 Final Committee Draft
JPEG 2000 Part 6 refers to the standard for compound documents.
MP3Gain
This product analyzes and adjusts MP3 files so that they all have the same volume. It appears to be free.
As of Septembery, 2003, Version 1.4.3 is shipping.
HaHaZip
A Win32 Zip compression utility. Looks very generic, and appears to be free.
LameFE
Billed as a front end for the Lame encoder, LameFE actually supports much more than that on the Win32 platform. Rip CDs, encode using Lame, Monkey’s Audio, or Ogg Vorbis, or playback using a similar batch of codecs.
Zoom Player
A media player that comes in a free and pay version. Although it’s labeled as a media player, it looks to me as though this is primarily inteded to be used as a DVD player.
Epigon Media Technologies
It’s a little hard for me to tell what Epigon is selling. They have a nice picture of some kind of board on their front page, but I don’t think they have any hardware for sale. They do appear to have audio codecs for MPEG-1, MPEG-2, and MPEG-4, as well as what appears to be […]
KZIP
Ken Silverman’s Zip utility. Ken says:
My own version of PKZIP. It’s quite a bit slower, and it’s a bit of a memory hog… but for good reason. KZIP creates smaller .ZIP files than PKZIP with maximum compression enabled! No, I didn’t cheat. You see… during compression, PKZIP gives up after it has found so many […]
ZipMix
Another Ken Silverman utility. Ken has this to say about ZipMix:
Sometimes, when you run 2 different .ZIP programs on the same data (PKZIP & KZIP for example), some files get compressed better in one program, while other files get compressed better in the other. ZIPMIX will take the best files from each one and create […]
OpenShiiva
OpenShiiva does just one thing: converts VOB files to MPEG-4 format. It does this on MacOS X. VOB files are wrapped MPEG-2 format streams, such as you might find on DVDs. You can expect a nice decrease in size when going from VOB to MPEG-4, so this is ideal for archiving DVD files to […]
Javascript Compression
Another compressor for HTML or Javascript files. This looks to be a Javascript implementation. Looks free.
Webcompression.org
This site is dedicated to discussion and explanation of HTTP compression with the Apache web server. Looks to me like the first place to go for information.
CiderPress
CiderPress is a Win32 programmer that is designed to support Apple II archiving formats. Full support for ShrinkIt (NuFX) archives, plus a bunch of features that provide glue functoins for dealing with AppleII stuff on modern Windows machines.
MP3 Streaming DownSampler
Damascus Porteng wrote this downsampler that will take an input MP3 stream and resample it at a lower bit rate. Looks like open source that will run on *NIX systems.
Yet another java id3 lib
A Java library that lets you read and write the ID3 tags embedded in MP3 files. Yep, it’s free.
IvyTV
IvyTV seeks to create an open source kernel mode driver for the iTVC15 familiy of MPEG codecs, which are found on the Hauppage PVR capture cards.
A Bit-Wise Adaptable Entropy Coding Technique
This paper describes an entropy encoder that can outperform Huffman or arithmetic coding.
ZipBackup
Another Win32 backup program. 30 day free trial, but you have to pay up after that.
Zip/JPEG Mask and Encryption
This cool program uses either Zip file or JPEG file to encrypt some of your data. I think it’s free, email me if I’m wrong.
Bee Archiver
This is an archiver. That’s all I know - the web page is in Russian, and the Babel Fish translation didn’t give me too much additional information.
Silesia compression corpus
Sebastian Deorowicz decided to create a compression corpus of his own, attempting to overcome some of the deficiencies he sees in the old guard.

Xceed Streaming Compression Library
The Xceed Streaming Compression Library is a high-performance “raw” compression library. It offers the ability to compress and decompress streaming data, buffers, strings or single files and supports multiple compressed data formats. Unlike the Xceed Zip Compression Library, this ultralight library doesn’t offer Zip file handling capabilities.
The Unzip Wizard
The folks at Softword Technology have this to say about their product: There are many unzipping software tools to unzip ZIP files, but the easiest and friendliest of them all is The Unzip Wizard! It appears that this product is aimed at providing the core functionality needed by novice users. Shareware.
Version 3.1.0 is shipping as […]
XZip and XUnzip - Add zip and/or unzip to your app
This CodeProject article gives you support for both zipping and unzipping files from archives without requiring a lib or dll. The code is absolutely free.
Update posted June 20, 2003.
ShipInBottle Archiver
This is a Russian language web site, so I’ll have to apologize in advance for any mistakes. As far as I can tell, this is a PPM-based archiver. I can’t tell if it’s free or not, so I’m listing it as both!

libDSP
A C++ library of digital signal processing routines. We link to it here because it includes a DCT algorithm, plus a few other possibly interesting routines.
