Lossless Python Packages

tamp

Tamp is a low-memory, DEFLATE-inspired lossless compression library.

telegram-slskd-local-bot

Telegram bot that turns a song name into a lossless file in your library: resolves it on Spotify, searches Soulseek through slskd, ranks the copies and lets you hear them first. Chat delivery sends the track in Telegram instead. Docker-ready.

terse-mcp

Shrinks your AI agent's tool output so it burns fewer tokens, without changing what the agent reads. Lossless by default, no decode step.

chromapakz

Lossless RGBD video codec — RGB + bit-exact 16-bit depth in one royalty-free WebM; encode/decode in the browser with no WASM, plus C++ and Python.

qobuz-dl-ultra

O melhor downloader audiófilo e gerente de biblioteca para Qobuz. Apresenta FLAC de alta resolução, metadados avançados (otimizados para Roon/DAP), ReplayGain nativo e um mecanismo de letras retroativo.

longhand

Lossless local memory for Claude Code. The full, unabbreviated version. Every tool call, every file edit, every thinking block — stored verbatim on your machine. Persistent memory without tokens.

audio-transcode-watcher

Automated multi-format audio transcoding service with real-time file watching and lyrics fetching

neural-weight-compression

Neural Weight Compression: lossless LLM weight compression decoded inside the CUDA matvec. BF16 31 % smaller and faster than cuBLAS; fp8 13 % smaller at native fp8 speed. Bit-identical weights.

rsack

Ransack「rsack」is a lossless Korean music downloader

ultracompress

Historical UltraCompress research and public CLI: pack structure checks and SHA-256 fingerprints.

lmzip

Fast lossless compression for large model weights: 34% off BF16 checkpoints, byte-for-byte identical, with a CUDA decoder at 111 GB/s

waxcut

Frame-accurate, lossless MP3 splitting and duration parsing in pure Python. No ffmpeg, no subprocess, no decode step.

lossless-hermes-py

Lossless Context Management (LCM) for Hermes Agent — DAG-based conversation summarization that never forgets. Python port of lossless-claw.

datacortex

World's best JSON/NDJSON compressor. Format-aware lossless compression engine in Rust - schema inference, columnar reorg, type-specific encoding. 2-3x better than zstd on structured data.

matplotlib-lossless-webp

Tiny Python package that forces lossless compression in matplotlib when saving WebP images

tokenizesentences

Tiny, dependency-free English sentence tokenizer.

fakeflacfinder

FakeFlacFinder is a read-only command-line tool that checks FLAC integrity and looks for signs that the audio was previously compressed using a lossy format such as MP3.
