gifsicle-bin 1.96.1

Pre-compiled gifsicle binary for GIF optimization

gifsicle-bin

Pre-compiled gifsicle binary distributed as a Python wheel.

Install with pip/uv and get gifsicle in your PATH — no brew install or apt install needed.

How is this different from pygifsicle?

pygifsicle is a Python wrapper around gifsicle that requires you to install the gifsicle binary separately (brew install gifsicle, apt install gifsicle, etc.). Use pygifsicle if your users can be expected to have gifsicle on their system already.

This package bundles the compiled gifsicle binary itself inside the wheel — nothing else to install. Use gifsicle-bin if you want end users to be able to use gifsicle without needing a system install at all (e.g. via uvx or pip install).

Built for agent-log-gif.

Installation

pip install gifsicle-bin
# or
uv add gifsicle-bin

Usage

Once installed, gifsicle is available as a command:

gifsicle -O2 --lossy=80 input.gif -o output.gif

Or from Python:

import subprocess
subprocess.run(["gifsicle", "-O2", "--lossy=80", "input.gif", "-o", "output.gif"])

Updating gifsicle version

gifsicle source is a clean git submodule — zero patches.

cd vendor/gifsicle && git fetch --tags && git checkout v1.XX && cd ../..

Update the version in pyproject.toml and config.h.cmake.in (grep for the old version). If configure.ac changed between versions, check for new HAVE_* defines and add matching entries to CMakeLists.txt + config.h.cmake.in.

To publish: git tag 1.XX && git push origin 1.XX — CI builds wheels for all platforms and publishes to PyPI via OIDC.
