qrcode
QR Code image generator
Decision gist · record as of 2026-08-14
Yes. qrcode is a mature, well-maintained library with no security issues, low install friction, and a permissive BSD license. It's suitable for any project needing QR code generation—from simple one-liners to complex styled codes. The single runtime dependency and optional image extras keep bloat minimal.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Image output requires optional dependencies: install with the pil extra for advanced image features, or the package falls back to built-in encoding.
- Low friction: pure Python with a single optional runtime dependency (colorama).
- Active maintenance, last commit 2026-03-25, and no known vulnerabilities.

What it is and what it does
qrcode is a pure-Python QR code generator that encodes text or binary data into Quick Response codes—two-dimensional barcodes readable by standard QR scanners. It supports multiple output formats: PNG images, SVG vector graphics, and ASCII art for console display. The package provides both a simple one-line API for quick generation and a full QRCode class for fine-grained control over error correction levels, code size, colors, and styling.
The library's main dependency is colorama for console output. Optional image dependencies are available via extras. It supports Python 3.9 through 3.13 and has been actively maintained since 2011, with no known security vulnerabilities. Use it to embed codes in web applications, generate codes for inventory systems, create scannable links in documents, or add QR functionality to CLI tools.
Use it for
- Generate QR codes for URLs in web applications or email campaigns to drive traffic or track engagement.
- Create inventory or asset tracking codes for warehouse or retail systems that can be scanned with mobile devices.
- Embed styled QR codes with custom colors in printed materials or marketing collateral.
- Build CLI tools that output QR codes as ASCII art or image files for quick sharing or documentation.
- Encode contact information or credentials into scannable QR codes for event check-ins or guest onboarding.
