pyStrich is a fast pure-Python module to generate 1D and 2D barcodes in PNG, SVG and other image formats. Currently it supports:

• Code 39 (code39)
• Code 128 and GS1-128 (code128)
• EAN-13 (ean13)
• Interleaved 2 of 5 and ITF-14 (itf)
• Data Matrix and GS1 Data Matrix (datamatrix)
• QR Code (qrcode)
• PDF417 (pdf417)
• Aztec Code (aztec)

PNG output requires Pillow, installable via the pyStrich[png] extra; SVG, EPS, DXF and terminal output do not. pyStrich supports encoding only, not decoding.

pyStrich was originally a fork of huBarcode. huBarcode was developed by HuDoRa from at least 2007, and has not been active since late 2013. Method B Ltd forked huBarcode as pyStrich in 2015 to provide Python 3 support and to continue development. pyStrich has been substantially enhanced over the years and has gone far beyond a simple port to Python 3. As of 2026, pyStrich is a modern Python package with full use of typing, linting and a comprehensive test suite.

Thanks to the folks at HuDoRa for the original huBarcode library that pyStrich grew out of.
