ollamazip

Bundle Ollama models into single portable archives for transfer between machines.

Why would I need ollamazip?

Installation

pip install ollamazip

# With zstd compression support (recommended):
pip install ollamazip[zstd]

# With the graphical interface:
pip install ollamazip[gui]

# GUI in a native desktop window (via pywebview):
pip install ollamazip[gui-native]

Usage

# Pack a model into a portable .ollamazip file
ollamazip pack llama3:8b
ollamazip pack mymodel:latest -o mymodel.ollamazip
ollamazip pack qwen3:27b --compress gzip

# Unpack on another machine
ollamazip unpack llama3-8b.ollamazip
ollamazip unpack mymodel.ollamazip --name newname:v2
ollamazip unpack mymodel.ollamazip --verify

# Inspect an archive without unpacking
ollamazip list mymodel.ollamazip

# List installed Ollama models
ollamazip models

# Launch the graphical interface (opens in browser)
ollamazip gui
ollamazip gui --native    # open in a native window (requires gui-native extra)

Graphical interface

ollamazip gui starts a small local web app (NiceGUI) that lets you:

• Browse installed Ollama models with sizes
• Pack any local model into a .ollamazip archive
• Rename or delete local models (with orphaned-blob pruning)
• Browse a folder of .ollamazip archives, inspect metadata, unpack, move, or delete them

By default it opens http://127.0.0.1:8734 in your browser. Pass --native to run in a standalone desktop window instead.

Features

• Single-file bundles: Packs the manifest and all content-addressed blobs into one archive
• Smart compression: Auto-selects zstd (if available) or gzip; override with --compress
• Blob deduplication: Skips blobs already present on the target machine during unpack
• SHA256 verification: --verify validates every blob against manifest digests
• Model renaming: --name newmodel:newtag imports under a different name
• Cross-platform: Works on macOS, Linux, and Windows; respects OLLAMA_MODELS env var
• No dependencies: Core functionality uses only the Python standard library; zstd is optional

How it works

Ollama stores models as a JSON manifest referencing content-addressed blobs (SHA256). ollamazip pack reads the manifest, collects all referenced blobs, and bundles them into a tar archive. ollamazip unpack extracts them into the target machine's Ollama model store (~/.ollama/models/).
