QRコード生成

QRコード生成 lets you create QR codes for links, plain text, Wi-Fi credentials, contacts and other payloads in seconds. It is useful anywhere you want to bridge offline surfaces and digital actions: packaging, flyers, menus, posters, slide decks or landing pages.

使い方

  1. 1

    Enter the payload

    Paste the URL, text, Wi-Fi string or other content that should open after scanning.

  2. 2

    Adjust the design

    Tune the QR size and colors so the final asset matches your layout, brand or print requirements.

  3. 3

    Download the PNG

    Save the finished QR code for use in print, web pages, presentations or internal materials.

技術的な詳細

A QR code reduces friction between a visual asset and a digital action. Instead of typing a URL manually, the user scans once and jumps straight into the intended flow.

That makes QR useful for marketing, events, retail, hospitality, printed materials and local business operations. One scan can replace several manual steps and improve response rates.

Because the generator runs in the browser, you can create a QR code, adjust the output size and download a ready-to-use PNG without waiting on a separate design workflow.
