CalcKitHow to Use the QR Code Generator
QR codes turn any link, text, Wi-Fi password or contact detail into a scannable square — perfect for business cards, menus, event posters, product packaging and "scan to pay" signs. This generator makes one instantly, free, with no sign-up or watermark.
Type or paste your text or URL, pick a size, and press Generate QR Code. Your code appears immediately — ⬇ Download PNG saves it for print or sharing. Larger sizes stay sharp on posters; the small size is fine for screens.
Three tips for codes that scan reliably: keep good contrast (dark code on light background), don't shrink printed codes below ~2 cm, and always test-scan with your own phone before printing a thousand flyers. For URLs, shorter links make simpler, easier-to-scan codes.
The image is generated by a free public QR API; your input is only used to create the image. Need a strong password to share via QR (like Wi-Fi)? Make it with our Password Generator first.
