FastLZ (MIT license) is an ANSI C/C90 implementation of Lempel-Ziv 77 algorithm (LZ77) of lossless data compression. Candleman 1 0 – rpg action & adventure platformer game. It is suitable to compress series of text/paragraphs, sequences of raw pixel data, or any other blocks of data with lots of repetition. It is not intended to be used on images, videos, and other formats of data typically already in an optimal compressed form.
The focus for FastLZ is a very fast compression and decompression, doing that at the cost of the compression ratio. As an illustration, the comparison with zlib when compressing enwik8 (also in more details):
Ratio | Compression | Decompression | |
---|---|---|---|
FastLZ | 54.2% | 159 MB/s | 305 MB/s |
zlib -1 | 42.3% | 50 MB/s | 184 MB/s |
zlib -9 | 36.5% | 11 MB/s | 185 MB/s |
FastLZ is used by many software products, from a number of games (such as Death Stranding) to various open-source projects (Godot Engine, Facebook HHVM, Apache Traffic Server, Calligra Office, OSv, Netty, etc). It even serves as the basis for other compression projects like BLOSC.
For other implementations of byte-aligned LZ77, take a look at LZ4, Snappy, Density, LZO, LZF, LZJB, LZRW, etc.
Usage
This free compressor can now compress an entire html web page or just a chuck of HTML code if you prefer. Compressed HTML for your Web Server. Having compressed HTML files online will save you a lot of money on your server bills if you have a very bandwidth heavy website. It's one of the easiest ways to optimize a website so start compressing. If you have JavaScript code or CSS Styles written directly in the HTML, this smart compression algorithm identify those code blocks and leave them as it is without compressing to make sure your html page load correctly. This tool avoid any STYLE, SCRIPT, PRE, TEXTAREA and BLOCKCODE code blocks been compress. Get information on the LG LA100VC.

Block Format
Let us assume that FastLZ compresses an array of bytes, called the uncompressed block, into another array of bytes, called the compressed block. To understand what will be stored in the compressed block, it is illustrative to demonstrate how FastLZ will decompress the block to retrieve the original uncompressed block.
The first 5-bit of the block, i.e. the 5 most-significant bits of the first byte, is the block tag. Currently the block tag determines the compression level used to produce the compressed block.
Block tag | Compression level |
---|---|
0 | Level 1 |
1 | Level 2 |
Javascript Condenser 1 4 – Quickly Compress Your Javascript Code Editor
The content of the block will vary depending on the compression level.
Block Format for Level 1
FastLZ Level 1 impements LZ77 compression algorithm with 8 KB sliding window and up to 264 bytes of match length.
The compressed block consists of one or more instructions.Each instruction starts with a 1-byte opcode, 2-byte opcode, or 3-byte opcode.
Instruction type | Opcode[0] | Opcode[1] | Opcode[2] |
---|---|---|---|
Literal run | 000 , L₅-L₀ | - | - |
Short match | M₂-M₀, R₁₂-R₈ | R₇-R₀ | - |
Long match | 111 , R₁₂-R₈ | M₇-R₀ | R₇-R₀ |
Note that the very first instruction in a compressed block is always a literal run.
Literal run instruction
For the literal run instruction, there is one or more bytes following the code. This is called the literal run.
The 5 least-significant bits of
opcode[0]
, L, determines the number of literals following the opcode. The value of 0 indicates a 1-byte literal run, 1 indicates a 2-byte literal run, and so on. The minimum literal run is 1 and the maximum literal run is 32.The decompressor copies (L + 1) bytes of literal run, starting from the first one right after opcode.
Example: If the compressed block is a 4-byte array of
[0x02, 0x41, 0x42, 0x43]
, then the opcode is 0x02
and that means a literal run of 3 bytes. The decompressor will then copy the subsequent 3 bytes, [0x41, 0x42, 0x43]
, to the output buffer. The output buffer now represents the (original) uncompressed block, [0x41, 0x42, 0x43]
.Short match instruction
The 3 most-significant bits of
opcode[0]
, M, determines the match length. The value of 1 indicates a 3-byte match, 2 indicates a 4-byte match and so on. The minimum match length is 3 and the maximum match length is 8.The 5 least-significant bits of
opcode[0]
combined with the 8 bits of the opcode[1]
, R, determines the reference offset. Since the offset is encoded in 13 bits, the minimum is 0 and the maximum is 8191.The following C code retrieves the match length and reference offset:
The decompressor copies (M+2) bytes, starting from the location offsetted by R in the output buffer. Note that R is a back reference, i.e. the value of 0 corresponds the last byte in the output buffer, 1 is the second to last byte, and so forth.

Example 1: If the compressed block is a 7-byte array of
[0x03, 0x41, 0x42, 0x43, 0x44, 0x20, 0x02]
, then there are two instructions in the there. The first instruction is the literal run of 4 bytes (due to L = 3). Thus, the decompressor copies 4 bytes to the output buffer, resulting in [0x41, 0x42, 0x43, 0x44]
. The second instruction is the short match of 3 bytes (from M = 1, i.e 0x20 >> 5
) and the offset of 2. Therefore, the compressor goes back 2 bytes from the last position, copies 3 bytes ([0x42, 0x43, 0x44]
), and appends them to the output buffer. The output buffer now represents the complete uncompressed data, [0x41, 0x42, 0x43, 0x44, 0x42, 0x43, 0x44]
.Example 2: If the compressed block is a 4-byte array of
[0x00, 0x61, 0x40, 0x00]
, then there are two instructions in there. The first instruction is the literal run of just 1 byte (L = 0). Thus, the decompressor copies the byte (0x61
) to the output buffer. The output buffer now becomes [0x61]
. The second instruction is the short match of 4 bytes (from M = 2, i.e. 0x40 >> 5
) and the offset of 0. Therefore, the decompressor copies 4 bytes starting using the back reference of 0 (i.e. the position of 0x61
). The output buffer now represents the complete uncompressed data, [0x61, 0x61, 0x61, 0x61, 0x61]

Long match instruction
The value of
opcode[1]
, M, determines the match length. The value of 0 indicates a 9-byte match, 1 indicates a 10-byte match and so on. The minimum match length is 9 and the maximum match length is 264.The 5 least-significant bits of
opcode[0]
combined with the 8 bits of opcode[2]
, R, determines the reference offset. Since the offset is encoded in 13 bits, the minimum is 0 and the maximum is 8191.The following C code retrieves the match length and reference offset:
The decompressor copies (M+9) bytes, starting from the location offsetted by R in the output buffer. Note that R is a back reference, i.e. the value of 0 corresponds to the last byte in the output buffer, 1 is for the second to last byte, and so forth.

Example: If the compressed block is a 4-byte array of
[0x01, 0x44, 0x45, 0xE0, 0x01, 0x01]
, then there are two instructions in there. The first instruction is the literal run with the length of 2 (due to L = 1). Thus, the decompressor copies the 2-byte literal run ([0x44, 0x45]
) to the output buffer. The second instruction is the long match with the match length of 10 (from M = 1) and the offset of 1. Therefore, the decompressor copies 10 bytes starting using the back reference of 1 (i.e. the position of 0x44
). The output buffer now represents the complete uncompressed data, [0x44, 0x45, 0x44, 0x45, 0x44, 0x45, 0x44, 0x45, 0x44, 0x45, 0x44, 0x45]
