Quick Response codes store data in a grid of black and white squares that any modern camera can scan. They bridge printed surfaces and digital destinations, guiding customers to websites, menus or product pages without typing. Because the pattern encodes error correction, a damaged code often remains readable, ensuring reliable engagement on packaging, posters or business cards.

Your QR Code Generator lets you craft branded codes without design software. Pick a content type, fine-tune colours, shapes and gradients, then preview the result instantly. The interactive interface updates the symbol as you change sliders, ensuring each tweak respects scanning standards while matching your campaign palette and layout restrictions.

Generate a Wi-Fi label, payment link or calendar invite and export it as PNG, SVG or PDF for placement in posters, packaging or slides. The high-resolution output scales cleanly, so the same file works on business cards and billboards alike, saving design time and avoiding raster artefacts. Verify contrast and test scans from multiple distances before committing to print.

Technical Details:

The generator runs entirely in your browser using a lightweight rendering engine that converts textual payloads into vector paths. No server communication occurs; every option change recalculates the matrix, colours and decorations in real time, then injects an updated <canvas> or <svg> into the preview container.

Parameters persist to the page URL as query strings, allowing you to bookmark or share presets with collaborators. Exports rely on client-side download APIs, and the PDF option builds a compact 80 mm × 80 mm document with embedded bitmap for predictable print sizing.

Multi-content payloads

Encode URLs, vCards, Wi-Fi credentials, SMS messages, calendar events and more without changing tools or syntax.

Live design controls

Adjust colours, dot shapes, eye styles and margins while the preview refreshes instantly, ensuring rapid visual iteration.

Gradient & frame styles

Add linear or radial gradients, rounded frames or dashed borders to match brand guidelines and highlight scanning cues.

Logo embedding

Drag a bitmap or vector onto the drop-zone to centre a logo, with automatic size and margin adjustments for scan safety.

Multi-format export

Download crisp PNG, resolution-independent SVG or ready-to-print PDF with one-click buttons for seamless asset delivery.

Step-by-Step Guide:

Follow these clear steps to craft and download a scan-ready code.

Select a payload under the Content legend, then fill the displayed fields.
Open the Design panel and tweak dot style, eye shape, colours and size.
Expand Gradient advanced options to overlay linear or radial colour blends.
Switch to Extras to choose a frame, edit its label or upload a logo image.
Watch the live preview update above the form; adjust until the scan matches expectations.
Click PNG (2×), SVG or PDF to export the artwork for deployment.

FAQ:

Common questions answered for swift onboarding.

Is my data stored?

No. All processing happens locally; nothing leaves your browser.

Which browsers work?

Latest Chrome, Edge, Safari and Firefox versions support the required graphics and download features.

Can I change size later?

Yes. Adjust the Size field and re-export; SVG remains sharp at any scale.

Why does my logo hide dots?

Increase the Logo scale margin or use a higher error-correction level for reliable reading.

How do I embed on a site?

Export SVG and insert it inline or as an image tag; ensure width and height fit the layout.

Troubleshooting:

Resolve common issues quickly.

QR will not scan – Confirm sufficient contrast and dot size above 2 px.
Exported PNG looks blurry – Use SVG or raise the Size value before downloading.
Gradient appears banded – Try radial mode or choose colours with similar luminance.
Logo upload fails – Ensure file size is under 2 MB and the format is PNG, JPG or SVG.
Frame label truncated – Shorten text or reduce font size within the Extras panel.

Advanced Tips:

Go further with subtle optimisations.

Use radial gradients to draw the eye toward the code centre without lowering contrast.
Store campaign parameters in a shortened URL to keep the encoded matrix compact.
Place white quiet zones around printed codes; four module widths is safe.
Embed a call-to-action line under framed codes to improve scan rates.
Save presets by bookmarking the URL after completing your design.

Glossary:

Key terms used in the interface.

Module: One square in the QR matrix.
Quiet zone: Blank margin surrounding the code, required for cameras to detect edges.
Error correction: Redundant data allowing reconstruction after damage; levels L to H.
Eye: Three position markers located at the corners of a QR symbol.
Payload: The text or data encoded within the QR code.
