intelhex
Python library for Intel HEX files manipulations
Decision gist · record as of 2026-08-14
Yes, if you work with Intel HEX files in embedded systems or microcontroller development. The package is stable, dependency-free, and widely used (top 5000 on PyPI). The dormant maintenance status is not a concern for a mature, single-purpose library with no known vulnerabilities, but verify compatibility with your Python version before relying on it for new projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Low install friction with no runtime dependencies.
- Maintenance is dormant—last release was 2020-10-20—but the package remains in production/stable status with an active repository and recent commits, suggesting it is mature and stable rather than abandoned.

What it is and what it does
intelhex is a Python library for reading, writing, and manipulating Intel HEX files, the de facto standard format for representing firmware and data in embedded systems and microcontroller programming. It provides both a programmatic API for working with HEX data in Python code and command-line utilities like hex2bin and bin2hex for format conversion.
The library has no runtime dependencies and installs as a pure Python wheel, making it lightweight and straightforward to integrate into embedded development workflows. It is classified as production/stable and supports Python 3.5 and later, though the last release was in 2020 and the project is now dormant—meaning it receives no active development but remains functional for its core use case.
Use it for
- Convert between Intel HEX and binary formats when preparing firmware for microcontroller programming.
- Parse and manipulate HEX files programmatically within embedded development toolchains.
- Extract or modify specific memory regions in HEX files before flashing to devices.
- Validate and inspect HEX file structure and content in build or CI/CD pipelines.
- Generate HEX files from scratch when building custom firmware packaging tools.
