A QR code should do one simple job: get someone from a physical object to the right place, without making them think about the technology. This walkthrough uses the free tool on The Tupy Show and gives you a practical handoff checklist for a flyer, card, or poster.
1. Decide what the scan should do
Choose the destination before designing the code. For a podcast flyer, link to the episode library or a specific episode. For a business card, a contact page may be more useful than a homepage. For a short message with no website, choose plain text instead.
Use a page you can maintain. If a QR code will be printed on hundreds of cards, a short URL on your own domain gives you control over what visitors see at that address. The QR image itself still contains a fixed value; changing the page at that address is a separate website task.
2. Generate it in the browser
Open the QR Generator, select Website link or Plain text, and enter your content. Website addresses without a scheme get https:// added automatically. Check the destination displayed underneath the preview—especially spelling, path, and any query parameters.
The tool offers four dark color choices against white and PNG sizes of 512, 1024, or 2048 pixels. Generation happens locally in your browser. There is no account, paid generation service, or redirect subscription built into the code. Your destination website may have its own requirements.
3. Pick PNG or SVG for the job
PNG is convenient for documents, social graphics, and tools that accept ordinary image uploads. SVG is useful when a designer or printer needs scalable artwork. Both downloads encode the same content.
Keep the square shape and the white space around it. DENSO WAVE specifies a clear margin four modules wide on each side of a standard QR code. A module is one small square in the grid. This generator includes that margin; avoid cropping it off or placing text inside it.
4. Test the actual finished design
A scan of the preview is only the first check. Put the exported code into the finished layout, print a sample at the intended size, and scan that sample. Try more than one phone, the likely viewing distance, and the lighting where people will use it. There is no single print size that covers every destination length and viewing situation.
Check the landing page as well as the scan. Does it load on mobile data? Is the expected content visible? Does it require a login the audience will not have? A perfectly readable code still disappoints if its destination is confusing.
A simple handoff checklist
Static codes do not contain a built-in expiration timer, but a deleted page, expired domain, or changed access setting can still make them unusable. Save the exported file alongside the destination URL so a future reprint is easy.
- The displayed destination matches the page or message you intended.
- The download keeps its square proportions and white border.
- The code has been tested inside the finished design, not just in isolation.
- A short, readable URL appears nearby for people who cannot scan.
- Someone is responsible for keeping the destination available.
