NanoZip is an experimental file archiver software. It consists of several original file compression algorithms, put into a single file archiver program aiming for high data compression efficiency. It has many experimental features, such as fine granular (i.e. not block based) parallel compression algorithms.

The latest NanoZip (2011) for 32-bit Windows, includes graphical user interface and command line interface. The other versions include only the command line interfaces. nanozip-0.09a.win32.zip d7b43d2f fecb19e2 ba36c5e5 da8cca6e c254f07b 3c132779 c3b82a2a 2bd8f114 (sha256) nanozip-0.09a.win64.zip 0bc7cfd0 5dec5417 d04d397c 937baf44 d0e4897d 97ae16c1 7ed8b130 c754d276 nanozip-0.09a.linux32.zip db94977e 80bbab02 d122e7bd 6f6f83c7 767931a4 014bde8e ef1b2a5a 9ae7dde1 nanozip-0.09a.linux64.zip e66dd3f9 e0a1da91 37a1483c 36c9979f 3ff1dbf1 175876a0 47504ee4 ff4b2cd7

Thanks for helping me with the website bills.

NanoZip (nz) has good compression performance over wide range of file types. For example: compressing 500 MB Linux binary distribution:

size (mb)
time (sec)
nz 0.09 -cc73724722
nz 0.09 -cO8316437
nz 0.09 -co916710
uharc 0.6b -mx96448363
7-zip 9.12 -mx991879
nz 0.09 -cD117232
rar 4.2 -m5117414
nz 0.09 -cd1316.51.9
gzip 1.3.3 -9159845
nz 0.09 -cf1691.92
gzip 1.3.3 -3170155
The '-cO' algorithm in NanoZip is the strongest known asymmetric compression algorithm. No other algorithm decompresses faster at this compression ratio. See thorough compression comparison with other file compressors.

Audio compression

NanoZip has special algorithms for compressing audio data. An example case compressing 211 MB WAV files:
size (mb)
time (sec)
nz 0.09 -cd1239.37.2
flac 1.2.1 -8124283.4
nz 0.09 -cf1283.13.1
flac 1.2.1 -11344.13.2
The above results are with NanoZip multithreading disabled.

Text compression

Much of the original work in NanoZip is build around text compression. An example case compressing 100 MB text file:
size (mb)
time (sec)
nz 0.09 -cc19.6112111
nz 0.09 -cO21.08.35.3
nz 0.09 -co21.74.52.5
7-zip 9.12 -mx27.51172.2
bzip2 1.0.528.211.85.3
nz 0.09 -cD28.52.90.5
rar 4.2 -m531.129.70.9
gzip 1.3.3 -937.912.71.16

Chess compression

NanoZip understands chess game notation (1. e4 e5...) and outperforms on such data. 100 MB example file:
size (mb)
time (sec)
nz 0.09 -cO11.810.73.1
nz 0.09 -co12.75.71.9
7-zip 9.12 -mx19.594.21.8
bzip2 1.0.519.914.84.5
rar 4.2 -m523.930.80.7
nz 0.09 -cd24.01.10.5
gzip 1.3.3 -929.813.31.0
No illegal moves are checked nor is there an integrated chess engine, hence the results could be improved.

Multimedia compression

NanoZip algorithms handle linear sequences (e.g. 'abcdef...', 'x0u1a2p3...') embedded in heterogeneous data. 700 MB example:
size (mb)
time (sec)
nz 0.09 -cc12612131174
nz 0.09 -cO128507120
uharc 0.6b -mx161698572
nz 0.09 -co16211718
7-zip 9.12 -mx16215416
nz 0.09 -cDP165525
nz 0.09 -cD188212.9
rar 4.2 -m519851.56.7
nz 0.09 -cd21310.52.6
bzip2 1.0.52409136
gzip 1.3.3 -92471627.3
nz 0.09 -cf2552.882.77
lzop 1.03 -13436.272.16

Parallel compression algorithms and space use

NanoZip algorithms are memory frugal and recognize similarities between two data blocks even if the distance between them is large. This effect is amplified in the parallel compression algorithms. (-cdP below and -cDP in earlier example.) No such algorithms are known in the computer science literature. These do not split the data into blocks, but compress the input as a continuous stream while utilizing multiple processors. 800 MB example case (compiler binaries) using 500 MB memory:
size (mb)
time (sec)
nz 0.09 -cO4335132
nz 0.09 -cdP6523.72.7
7-zip 9.12 -mx972229.8
nz 0.09 -cF997.85.7
uharc 0.6b -mx101539401
rar 4.2 -m514350.55.2
gzip 1.3.3 -92281138.1

Archiver architecture

NanoZip outperforms other file archivers using a single thread only. The file archiver architecture allows parallel processing on multiple levels. 1) Independent threads for file reading and writing 2) The compression algorithms are designed in such way that parts of the compression can be done ahead and other threads finish or compliment the compression that was began earlier. 3) Some algorithms (depending on the data content) run with full CPU utilization regardless of number of processors available. 4) High level archiver architecture allows the entire process to be run in multiple branches (controlled by the '-p' -switch) by splitting the input task in any arbitrary number of blocks.


NanoZipLTCB is a subset of NanoZip compression library to highlight the performance for compressing plaintext with large memory model (multi-gigabyte). It compresses at the rate of 16 MB/s and decompresses 32 MB/s on modern hardware with the compression ratios over 6.2:1. No other file compressor compresses (and/or decompress) faster at these compression ratios. It only accepts the files from the large text compression benchmark. nanozipltcb-0.09.linux64.zip (2010) 0a587667 2c9a497c 2b61338a 87ac98a0 80f484f7 eaa1317e 7fe6d995 3cd29e21

Suffix sorting

NanoZip has original high performance algorithm for computing Burrows Wheeler Transform (BWT).
total seconds187.454322.928162.504126.592125.202
The table shows approximated Manzini Corpus results based on Yuta Mori's timings [4] for the latest suffix array construction algorithms. With the exception of MSufSort3 all algorithms work with similar space requirements. The R08 timings are adjusted by the ratio of MSufSort3 timings done with the same hardware as R08.


BWMonstr has the highest compression ratio amongst pure Burrows- Wheeler compression algorithms. It achieves the result of 203476 (2.1174 bpb) for book1 from the calgary corpus, which is better than most PPM and CM compression algorithms. The program has the lowest known space requirements (~0.6N) for computing both BWT transform and post-transform compression. This is an unoptimized demo compressor (with command line interface only). It is not indended for practical file compression purposes. bwmonstr.002.win32.zip (2009) 77895735 0d7f1cc7 367ce2c8 154389b4 87b0e7d6 2046bff9 3273b538 b0b9b891 See detailed compression comparison.
