How to create a QR code online for free (logo, Wi‑Fi & SVG)

Generate a scannable QR code from a link, Wi‑Fi login, or text. Customize colors, add a logo, and download PNG or SVG — 100% in your browser.

Step-by-step

  1. 1

    Open the QR Code Generator

    Tools → QR Code Generator, or /en/tools/qr-code-generator. The studio loads in the workspace — no install.

  2. 2

    Choose the payload

    URL, Text, Wi‑Fi, Email, Phone, SMS, or WhatsApp. For Wi‑Fi, enter the SSID and password.

  3. 3

    Customize

    Set size, quiet zone, error correction (L/M/Q/H), and foreground/background colors. Optionally add a logo — High correction is applied automatically.

  4. 4

    Download or copy

    Save PNG for print and chat, SVG for the web, or copy the PNG to the clipboard.

Overview

A QR code generator should encode your link or Wi‑Fi password on the device — not on someone else’s server. wikawe builds the code in your browser, lets you pick colors and a center logo, then exports PNG or SVG with no account.

Many “free QR” sites store every URL you type and stamp a watermark until you pay. Guest Wi‑Fi passwords, unpublished campaign links, and internal docs should never be uploaded just to draw a square barcode.

Why a privacy-first QR generator matters

Many “free QR” sites store every URL you type and stamp a watermark until you pay. Guest Wi‑Fi passwords, unpublished campaign links, and internal docs should never be uploaded just to draw a square barcode.

wikawe encodes locally. Logos are read as a data URL and drawn on a canvas in this tab. Download files are created on your device.

Common use cases

People search for how to create a qr code when they need a fast result without installing software. Print a Wi‑Fi QR so guests join without typing the password. Put a branded logo in the center of a campaign URL code. Export SVG for a website or packaging die-line that must stay sharp. Share a WhatsApp or email QR on a business card or table tent.

Generate, scan once on your phone, then download PNG or SVG — still on this device.

Private QR generation in the browser

The payload is encoded locally. Nothing is stored in a wikawe database.

Logo files are never uploaded — they are read in this tab and composited onto the canvas or SVG.

If the code will not scan

Increase contrast, enlarge the code, and add margin. Avoid busy backgrounds behind a printed QR.

If you added a logo, remove it or shrink it, and keep error correction on H. Try another camera app if one reader fails.

Pro tips

  • Keep high contrast. Light gray on white often fails in print.
  • Leave a quiet zone (margin) around the modules so camera apps can lock on.
  • Scan with your phone before a large print run, especially after adding a logo.
  • Prefer SVG when the code will be scaled in a design tool; PNG when you need a raster for WhatsApp or Instagram.

Frequently asked questions

Is the wikawe QR code generator free?+

Yes. Unlimited codes, logo overlay, and PNG/SVG export with no signup and no watermark.

Does creating a QR upload my data?+

No. Generation runs in JavaScript in your browser. URLs, Wi‑Fi passwords, and logos never go to wikawe servers.

Will a logo break scanning?+

A small centered logo (about 22% of the code) plus High (H) error correction is designed to stay scannable. Always test before printing.

PNG or SVG?+

PNG for print, chat, and social. SVG for websites and vector design files that must stay crisp at any size.
