batchqr

Generate QR codes in large batches with parallel processing.

Features

• Batch generation — process thousands of QR codes in parallel
• Multiple input formats — CSV, JSON, Excel, or Python lists
• Multiple output formats — PNG, SVG, PDF, EPS
• Flexible export — individual files, ZIP archives, or PDF label sheets
• Styling — custom colors, logo overlays, preset themes
• CLI & API — use from the command line or as a Python library
• Fault-tolerant — per-item error handling, failed items don't kill the batch

Quick Start

Python API

import batchqr

# Single QR code
batchqr.make("https://example.com").save("qr.png")

# Batch generation
results = batchqr.batch([
    "https://example.com/1",
    "https://example.com/2",
    "https://example.com/3",
]).save_all("./qrcodes/")

From CSV

import batchqr

batchqr.batch.from_csv("data.csv").save_zip("qrcodes.zip")

CLI

# Generate from inline data
batchqr make "https://example.com" -o qr.png

# Batch from CSV
batchqr batch data.csv --output ./qrcodes/

# Legacy CLI still works
qrbatch generate --input data.csv --output ./qrcodes/ --format png

Configuration

from batchqr import QRConfig

config = QRConfig(
    error_correction="H",   # L, M, Q, H
    box_size=10,
    border=4,
    fg_color="#000000",
    bg_color="#ffffff",
    image_format="png",
)

Styling

import batchqr

# Use a preset theme
qr = batchqr.make("https://example.com").theme("corporate-blue").save("styled.png")

# Or customize directly
qr = batchqr.make("https://example.com").color("#1a1a2e", "#ffffff").style("rounded").save("custom.png")
