QR Code Generator
Create free, high‑resolution QR codes for links, text, Wi‑Fi, contact info and more. Customize colors, add a logo, and download as PNG or SVG.
QR Code Generator Tool
Tip: Use SVG for print and design tools (Canva, Figma, Illustrator) and PNG for quick sharing.
How this QR code generator works
This tool creates static QR codes directly in your browser using open QR standards (ISO/IEC 18004). Your content is encoded into a matrix of black and white modules that can be read by any modern smartphone camera.
Unlike many online generators, this page does not require an account, does not watermark your codes, and lets you download high‑resolution PNG or infinitely scalable SVG files suitable for both web and print.
Supported QR content types
- URL – open a website, landing page, app store link, or social profile.
- Text – show a message, coupon code, or instructions directly on screen.
- Wi‑Fi – let visitors join your network without typing the password.
- Email – pre‑fill recipient, subject, and body in the user’s email app.
- vCard – share full contact details that can be saved in one tap.
- SMS – open the SMS app with phone number and message ready to send.
Error correction levels explained
QR codes use Reed–Solomon error correction so they can still be scanned if partially damaged or covered. The higher the level, the more redundant data is stored:
- L (Low) – recovers ≈ 7% of data. Smallest code, best for screens.
- M (Medium) – recovers ≈ 15%. Good default for most uses.
- Q (Quartile) – recovers ≈ 25%. Safer when adding a small logo.
- H (High) – recovers ≈ 30%. Best for logos or harsh environments.
Higher error correction makes the pattern denser. If you plan to overlay a logo or print the code on uneven surfaces, choose Q or H and keep the logo under about 30% of the QR’s width.
Best practices for reliable scanning
- Maintain a clear quiet zone (blank margin) around the code – this tool can add it automatically.
- Ensure high contrast between foreground and background (e.g., dark code on light background).
- Avoid inverting colors (light code on dark background) unless you test thoroughly.
- For print, use at least 2–3 cm (≈1 inch) side length for close scanning.
- Test your QR code with multiple devices and apps before mass printing.
Static vs. dynamic QR codes
This generator creates static QR codes: the content is embedded directly in the pattern and cannot be changed after printing. This is ideal for:
- Permanent URLs that you control (e.g., your own website or redirect links).
- Wi‑Fi credentials, contact details, or fixed text.
- Use cases where you don’t need analytics or editing.
If you need to change the destination later, encode a short URL that you control (for example, a redirect on your own domain) and update the redirect target when needed.
QR Code Generator FAQ
Are QR codes generated here free to use commercially?
Yes. QR codes created with this tool are free to download and use in personal or commercial projects. We do not add watermarks or tracking. Always ensure that the content you encode (logos, links, text) complies with copyright and trademark laws.
Do these QR codes expire or stop working?
No. Static QR codes do not expire. As long as the underlying content (for example, your website URL) remains valid and reachable, the QR code will continue to work indefinitely.
What file format should I use: PNG or SVG?
Use SVG when you need perfect sharpness at any size (logos, posters, packaging, vector design tools). Use PNG for quick sharing in documents, slides, or messaging apps. This generator lets you download both.
Can I track scans or edit the QR code later?
This tool does not provide analytics or editable (dynamic) QR codes. To make a destination changeable, encode a redirect URL that you control and update the redirect on your server. For scan tracking, use web analytics on the landing page or a link shortener that supports statistics.
