Frequently Asked Questions

How many QR codes can I generate at once?

You can generate up to 500 QR codes per batch. This limit ensures smooth performance in the browser. For larger batches, simply run the tool multiple times.

What file formats are supported for export?

You can download your QR codes in PNG, JPG, or SVG format. PNG is recommended for most uses, while SVG is ideal for print materials that require scalability.

PNG/JPG

Raster Formats

Best for digital use
Fixed resolution
Smaller file sizes
Universal compatibility

SVG

Vector Format

Perfect for print
Infinitely scalable
Crisp at any size
Editable in design tools

Does my data get uploaded to a server?

No. Everything runs entirely in your browser. Your text, CSV files, and generated QR codes are never sent to any server. The ZIP file is also created locally on your device.

100% Client-Side Processing: All operations happen in your browser using JavaScript. No data transmission occurs.

What CSV format does the tool accept?

The tool accepts standard CSV files (.csv) and plain text files (.txt). It automatically detects whether the first row is a header and lets you choose which column to use for QR data and file naming.

What does "Error Correction Level" mean?

Error correction determines how much damage a QR code can sustain and still be scannable. Higher levels add redundancy to the code, making it more resilient but slightly larger.

Level	Recovery	Best For
L (Low)	~7%	Clean environments, digital displays
M (Medium)	~15%	General purpose, most print materials
Q (Quartile)	~25%	Outdoor use, small prints
H (High)	~30%	Harsh environments, tiny codes

Recommendation: Use level M for most applications. Choose H for QR codes that will be printed small or placed in harsh environments.

Can I customize the colors of all QR codes at once?

Yes. Open the Customize QR Code panel before generating. Any color, size, or error correction settings you choose will apply uniformly to all QR codes in the batch.
