Bulk QR code generator — thousands of codes from one CSV

Generating codes one at a time stops working somewhere around the twentieth. The bulk generator takes a CSV file and returns a ZIP of finished codes, named from a column you choose.

How it works

• Upload a CSV where one column holds the link or value, and another holds the name
• Choose which column is which, and add a prefix if your values are partial
• Pick colours, module shape, size and file format
• Download a ZIP containing every code plus a manifest listing what each file encodes

Nothing is uploaded

Generation runs inside your browser. Your spreadsheet never reaches a server, which matters when the rows are customer records, ticket numbers or asset tags.

What people use it for

• Event tickets, one unique code per attendee
• Table codes for a restaurant, numbered by section
• Asset and machine tags across a factory floor
• Product labels carrying batch and warranty references
• Student or employee ID cards

How long it takes

Roughly a minute for a thousand PNGs at 512 pixels. Larger sizes and larger jobs take proportionally longer, and the tab needs to stay open while it runs.
