Tips for Better QR Codes
Error Correction Level
For printed materials, choose High or Quartile — they stay readable even if partially damaged or covered. For screen-only use, Low or Medium keeps the code compact.
Size Guide
Business cards: 300 px or more. Posters and banners: 800 px+. Social media icons: around 200 px. Larger sizes ensure reliable scanning from a distance.
Color Contrast
Always keep the foreground darker than the background. Low contrast between the two colors can make the code unreadable by scanners.
SVG vs PNG
SVG scales to any size without losing quality — ideal for print. PNG works everywhere and is better for web and messaging apps.
Common Use Cases
Put a QR code on business cards, flyers, or posters to link directly to your site or social profile.
Encode your Wi-Fi credentials so guests can connect by scanning — no need to type the password.
Embed ticket IDs or registration codes for fast, contactless event entry.
Encode contact information so recipients can save it to their phone with one scan.
Link printed materials to online menus, product pages, or PDF catalogs.
Embed payment URLs for quick checkout at shops, markets, or online invoices.
Frequently Asked Questions
Do QR codes expire?
No. QR codes generated here are static — the data is encoded directly into the image. They will work as long as the encoded content (URL, text, etc.) remains valid.
What is the maximum text length?
QR codes can hold several thousand characters. However, longer text creates denser patterns that are harder to scan. For best results, keep URLs short and text concise.
Can I overlay a logo on my QR code?
Yes, if you set the error correction level to High (30%). The built-in redundancy allows part of the code to be covered — typically up to about 30% of the area — and still be readable.
Do colored QR codes still scan?
Yes, as long as there is sufficient contrast between the foreground and background. Dark foreground on light background works best. Avoid light-on-light or dark-on-dark combinations.
Is my data sent to a server?
No. The QR code is generated entirely in your browser. Your text and URLs are never transmitted to any server.
Can I use generated QR codes commercially?
Yes. QR codes you create here are yours to use freely for any purpose — personal, commercial, or educational — with no restrictions.
