Frequently asked questions
Is this really free and private?
Yes. This tool runs entirely in your browser using JavaScript. Your content never leaves your device — nothing is uploaded to any server. The code is open and transparent.
What's the difference between error correction levels?
Error correction allows QR codes to remain readable even if partially damaged or obscured. Low (L) is 7% redundancy, Medium (M) is 15%, Quartile (Q) is 25%, and High (H) is 30%. Higher levels mean larger, denser codes but better resilience.
How much text can I encode?
QR codes can technically hold up to ~4,000 alphanumeric characters, but practical limits are lower. For best scannability, keep content under 300 characters. Longer text creates denser codes that are harder to scan reliably.
Can I use these QR codes commercially?
Yes. QR code technology is open and standardized (ISO/IEC 18004). The codes you generate are yours to use however you like — personal, commercial, printed materials, digital displays, products, or marketing.
What image format should I choose?
PNG is recommended for QR codes because it's lossless and maintains sharp edges. For print, choose 512px or 1024px. For digital use, 256px is usually sufficient. Avoid JPEG — compression artifacts can interfere with scanning.
