How to Generate QR Codes in Bulk From a CSV (Free)

Making one QR code is easy — making three hundred for event tickets, asset labels, or product links is the painful part. A bulk generator turns a list into a folder of QR images in one step. Here's how to do it for free in your browser.

Generate QR codes in bulk

1. Open the free Batch QR Code Generator.
2. Paste your list or upload a CSV (one value per line/row — a URL, text, or ID).
3. Choose the QR size.
4. Click generate and download the ZIP containing every QR code.

All codes are generated on your device, so your data is never uploaded.

Preparing your CSV or list

The cleaner your input, the cleaner your output:

• One value per row. Each line becomes one QR code.
• Use full URLs. Include https:// so scanners open links directly.
• Keep it consistent. A single column of values is easiest; descriptive, unique values make the downloaded files easy to match up later.

Choosing a size

• Small (e.g. 128–256 px) — fine for on-screen links and ticket PDFs.
• Large (512 px+) — better for print, labels, and signage, where the code must scan from a distance or survive scaling.

When in doubt, generate larger; you can always scale a QR down, but scaling up loses sharpness.

Common use cases

• Event tickets — a unique QR per attendee for fast check-in.
• Asset and inventory labels — encode IDs and stick them on equipment.
• Marketing and packaging — point each product or campaign to its own link.

For one-off codes, the single QR Code Generator is quicker; to confirm a generated code scans correctly, use the QR Code Reader. If you need 1D barcodes instead, try the Barcode Generator.

Privacy note

The Batch QR Code Generator builds every code in your browser — your list and the resulting ZIP never touch a server.

Frequently asked questions

How many codes can I make at once? Large batches use more memory; if a run fails, split your list into smaller chunks.

Are my values uploaded? No. Generation happens entirely in your browser.

When a static bulk generator isn't enough

These QR codes are static — each one encodes a fixed value forever. That's perfect for fixed asset IDs or permanent product links, but it has real limits. You can't edit the destination after printing, so if a campaign URL changes you must regenerate and reprint every code. There's no scan tracking either: a static code can't tell you how many people scanned it or where. And the tool encodes exactly what you give it, so a typo in row 200 becomes a dead QR on 200 labels — proofread the source list, and spot-check a few outputs with the QR Code Reader. If you need editable destinations or scan analytics, you want a dynamic QR service (which redirects through a tracking URL) rather than a static batch.
