It ships as pre-built wheels for macOS, Linux, and Windows, or can be compiled from source to enable platform-specific optimizations.\n\nOnce imported, hdf5plugin makes these filters transparent to h5py workflows. This is useful for scientific and data-intensive applications where the default gzip compression is insufficient or where specialized algorithms offer better performance or compression ratios.","worth_installing":"Yes, if you work with HDF5 files and need compression beyond gzip. The package is actively maintained, has no known vulnerabilities, and offers a straightforward import-and-use interface. Verify that the embedded filter licenses align with your project before committing, and be aware that source compilation may be needed to unlock platform-specific performance gains."},"id":"hdf5plugin","links":{"html":"https://skillfed.io/packages/hdf5plugin","md":"https://skillfed.io/packages/hdf5plugin.md","pypi":"https://pypi.org/project/hdf5plugin/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-06-25","license_spdx":null,"license_treatment":"unclear","name":"hdf5plugin","python_support":"supports_current","summary":"HDF5 Plugins for Windows, MacOS, and Linux"},"popularity":{"monthly_downloads":661299,"position":5451,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"7.0.0"}
