Simler v50.0 — Universal Lossless Compressor
Simler is a fast, universal lossless compressor designed for text, images, audio, PDFs, and binaries.
It supports multiple algorithms, integrity checks, streaming I/O, and can be used both from CLI and Python.
Key Features:
Algorithms: Huffman (word/phrase-aware), zlib, gzip, lzma
Integrity checks: sha256, crc32, or none
Streaming/chunked I/O for large files (memory-friendly)
CLI + Python API support
Phrase mode for better text compression
Multi-platform: works on desktops, servers, and edge devices
Suitable for storage savings, DB/AI pipelines, and large dataset handling
---
How to Use
Command Line
Compress a file:
python simler.py input_file output_file -a auto -l 6 --phrase --integrity sha256
Options:
input_file – file to compress
output_file – compressed output (.sim recommended)
-a / --algo – algorithm: auto, huffman, zlib, gzip, lzma
-l / --level – compression level 1–9
--phrase – enable Huffman phrase mode (text only)
--integrity – checksum: sha256, crc32, or none
Decompress a file:
python simler.py input_file.sim output_file --decompress
Automatically detects algorithm from metadata
Verifies integrity if SHA256 or CRC32 is used
---
Python API
from simler import Simler
# Initialize compressor
sim = Simler(algo="auto", level=6, integrity="sha256")
# Compress a file
sim.save_sim("data.txt", "data.sim", phrase_mode=True)
# Decompress a file
data = sim.load_sim("data.sim")
# Compression ratio
ratio = sim.get_compression_ratio("data.txt", "data.sim")
print(f"Compression ratio: {ratio:.2f}%")
API Parameters:
algo – compression algorithm
level – compression level (zlib/gzip/lzma)
phrase_mode – Huffman phrase mode for text
integrity – checksum type
Notes:
Huffman mode works best on UTF-8 text and may need sufficient RAM for dictionary building
Binary/non-text files default to zlib/lzma/gzip for reliability
Supports large file compression with minimal memory overhead
