Frequently Asked Questions (FAQ)

Yes, BatchQR is 100% free to use. There are no limits on the number of QR codes you can generate. We believe in providing accessible tools for everyone.

Your data is completely secure. We use client-side processing (WebAssembly/JS), which means your CSV files and text data are processed strictly on your computer. Nothing is ever uploaded to our servers, ensuring total privacy.

WebAssembly (Wasm) is a high-performance technology that runs in your web browser. By using Wasm, we can execute the QR code generation logic directly on your machine. This avoids the need to send your sensitive data to a server, making the process faster and infinitely more secure.

Error Correction allows a QR code to be partially damaged or obscured and still be readable. We offer four levels: Low (L), Medium (M), Quartile (Q), and High (H). A higher level adds more redundancy, making the QR code more robust, but also increases its density. For most use cases, 'Medium' is the perfect balance.
