How to create a QR code with logo

Generate a real, scannable QR code with custom colors and an optional centered logo, entirely in your browser.

  1. 1

    Pick a content type

    Select URL, Wi-Fi, vCard, SMS, Email, or Phone at the top of the tool.

  2. 2

    Fill in the fields

    Enter the URL, network credentials, contact details, or whatever your preset requires. The encoded string preview updates live.

  3. 3

    Customize colors and quiet zone

    Pick foreground and background colors. The default quiet zone (2 modules) is fine for most uses — increase it for physical printing.

  4. 4

    Optionally add a logo

    Upload a PNG/SVG logo and slide its size between 10–30%. Error correction is auto-set to H so the QR remains scannable.

  5. 5

    Download PNG or SVG

    Click PNG for raster or SVG for print/design use. The QR is saved directly from your browser — no upload required.

자주 묻는 질문

Are the QR codes generated by this tool real scannable QR codes?

Yes. We use the official QR Code encoder (ISO/IEC 18004) via the qrcode library — each code is a valid, scannable QR code that works with any phone camera or reader app. Earlier builds used a cosmetic pattern that looked like a QR code but was not scannable; that has been fixed.

Can I add my logo in the center of the QR code?

Yes. Upload your logo via the Logo panel and slide the size between 10–30% of the QR. The generator automatically forces Error Correction level H (30% redundancy) so the underlying data stays readable despite the occlusion.

What kinds of data can I encode — just URLs?

Six presets are supported out of the box: URL, Wi-Fi credentials (WPA/WEP/open), vCard contact, SMS message, Email with subject + body, and phone number. Each preset encodes to the canonical text format (e.g. `WIFI:T:WPA;S:...;P:...;;` for Wi-Fi, `BEGIN:VCARD... END:VCARD` for contacts).

How much data can I fit in a single QR code?

Up to ~4,296 alphanumeric characters or ~2,953 bytes at the lowest error correction level, but practical limits are much smaller. Shorter input keeps the QR easy to scan on small displays — for URLs we recommend staying under 200 characters.

Which error correction level should I choose (L, M, Q, H)?

L = 7% recovery (smallest QR), M = 15% (good default), Q = 25%, H = 30% (largest but survives damage/logos). Use M for screen display, Q or H for print or anywhere the code might get scratched. With a logo overlay we force H automatically.

Do my QR codes expire? Can they be tracked?

No. The QR is generated entirely in your browser and encodes the content directly — there is no redirect through our servers, no tracking, no expiration. The QR works offline forever once printed.

PNG or SVG — which export should I pick?

Choose SVG if you plan to print at any size or embed in design files (it is resolution-independent and tiny). Choose PNG for social media, email signatures, or anywhere a raster image is expected. Both are rendered with the same encoder.
