Batch-generate QR codes for links

To batch-generate QR codes for a list of links, here’s a step-by-step method you can use with Python:

Step 1: Prepare Your List of Links

Create a text or CSV file (links.txt or links.csv) with one URL per line.

Example (links.txt):

arduino
CopyEdit
https://example.com/page1
https://example.com/page2
https://example.com/page3

Step 2: Use Python to Generate QR Codes

python
CopyEdit
import qrcode
import os

# Create a folder for the QR codes
output_folder = 'qr_codes'
os.makedirs(output_folder, exist_ok=True)

# Read links from a file
with open('links.txt', 'r') as file:
    links = [line.strip() for line in file if line.strip()]

# Generate and save QR codes
for index, url in enumerate(links, start=1):
    img = qrcode.make(url)
    img_path = os.path.join(output_folder, f'qr_code_{index}.png')
    img.save(img_path)

print(f"Generated {len(links)} QR codes in the '{output_folder}' folder.")

Notes:

• You can customize filenames based on the URL content instead of using an index.

• To use this, you need the qrcode Python library:

  bash
  CopyEdit
  pip install qrcode[pil]
  

Let me know if you want a version that also embeds logos, custom colors, or different formats like SVG.
