QR code generator

Client

Turn a URL, contact block, or Wi‑Fi string into a scannable PNG or SVG. Use the builders for structured Wi‑Fi and vCard payloads, adjust colors and size, add an optional center logo, then download or copy—no upload to our servers.

Generate

?

Builds the QR matrix in your browser, then draws a PNG you can download or copy. Payloads never leave your device.

Logos sit on a white pad in the center and use high error correction—keep them small and always test with a real camera before printing. Very long payloads produce denser patterns.

Payload builders

Fill fields and apply to the editor—then generate or use auto-refresh. Wi‑Fi strings follow the common WIFI: format; vCard is version 3.0.

Wi‑Fi

vCard

Max 2,048 characters. Capacity depends on length and error correction—very dense codes are harder to scan.

Print-friendly:

Colors

Place the PNG on a contrasting background for reliable scans.

Center logo (optional)

Upload a square-ish icon or mark. It is drawn on a white pad in the middle—keep it modest and test with a real phone before printing.

Common use cases

  • Share a landing page, menu, or signup link on posters and stickers.
  • Use the Wi‑Fi builder so guests scan to join without typing SSID or password.
  • Build a vCard from form fields instead of hand-writing BEGIN/VCARD lines.
  • Export SVG for sharp vector placement or a large PNG width for print—test scans on paper.

Common mistakes to avoid

  • Oversized logo or low contrast

    A logo that covers too much of the symbol or colors with little contrast can fail to scan. Shrink the logo, increase quiet zone, or pick clearer module colors.

  • Transparent background on busy artwork

    If “light” modules are transparent, avoid placing the QR on noisy or same-colored backgrounds—give the code a clean, contrasting surface.

FAQ

Is my QR content sent to Toolcore?

No. Generation uses JavaScript in your browser; we do not receive your text, images, or exported PNG.

Why does adding a logo force high error correction?

Covering part of the code removes some modules. Level H (high) restores redundancy so many phones can still decode the payload.

What is the maximum text length?

You can enter up to about 2,048 characters in the editor, but practical QR capacity is lower and depends on encoding and error level. Prefer short URLs for printed materials.

Why does SVG not show my logo?

SVG export is the QR pattern only (vector modules). The center logo is drawn on the PNG canvas after generation—use PNG for branded print, or add artwork in your design tool using the SVG as a base.
