How to Create a QR Code (Step-by-Step Guide for Beginners)
By Diljit Ramachandran · /about · Published · Last updated · 3 min read
A QR code (Quick Response code) is a two-dimensional barcode that stores data, such as a web address, WiFi login or contact card, in a grid of black and white squares. To create one, open a generator, pick a type, enter your content, style it and download the image. It takes about two minutes.
How do you create a QR code?
Follow these five steps in a generator such as QRCodeStack.
- Decide what it should open. A website, a WiFi login, a PDF or a contact card; this also tells you whether it should be static or dynamic (see below).
- Choose the type in the generator. There are over 40, including website URL, WiFi, PDF, vCard, YouTube and Google Maps.
- Enter the content. Paste a URL, or give a WiFi network name, password and encryption type.
- Style it. Set colors, dot patterns and corner styles; the preview updates as you go.
- Download it. Choose PNG, SVG, JPEG or PDF; SVG suits print. Dynamic codes also save to your dashboard for scan tracking and edits.
For a plain black-and-white static code, the free QR code generator needs no signup and adds a small “Powered by qrcodestack.com” line. Colors and a logo on static codes need a paid plan on the pricing page, from $9/month.
How do you add a logo to a QR code?
Upload your logo file (up to 2 MB) in the customization panel; it is centered and sized automatically. This works because of error correction: at the highest level, about 30% of the code’s data can be restored when part of the pattern is covered. Keep the logo small; see creating a QR code with a logo.
How do you make QR codes for a website, WiFi or a PDF?
Website: choose the website type and paste the full URL. A dynamic code lets you change the URL later; a static one embeds it permanently.
WiFi: enter the network name, password and encryption type (WPA/WPA2 is the most common) so guests join without typing. See the WiFi QR code generator.
PDF: upload the file and the code opens it when scanned. With a dynamic code you can replace the PDF later without reprinting; see the PDF QR code generator.
Should you make a static or dynamic QR code?
Make it dynamic if the content might change after you print, and static if it is permanent. A static QR code is a fixed pattern holding the data itself; a dynamic QR code is a redirect you can edit. See static vs dynamic QR codes.
| Static | Dynamic | |
|---|---|---|
| Change the destination after printing | No | Yes |
| Scan analytics | None | Device, browser and scan time; city on Business and trial |
| If you stop paying | Keeps working | Stops redirecting |
| Best for | WiFi passwords, contact cards, fixed URLs | Campaigns, menus, anything that may change |
What makes a QR code scan reliably?
Check these five points before you print.
- Test before printing: scan with more than one device before a bulk print.
- Keep contrast high: use dark dots on a light background.
- Leave the quiet zone: a blank margin four modules wide on every side, the width Denso Wave specifies.
- Print it large enough: at least 2 x 2 cm for close range, larger for posters; see the size guide.
- Add a call to action: text such as “Scan to visit our website” tells people what to expect.
Common questions
Is it free to create a QR code? The free generator makes a black-and-white static PNG with no signup. Dynamic codes start with a 7-day trial, no credit card, then paid plans from $9/month.
Do QR codes expire? Static codes never expire because the data is in the image. Dynamic codes work while your subscription is active.
What is the best QR code generator? It depends on the job: a free generator is enough for a plain static code. For codes you edit and track, compare codes per plan, what the analytics show and what happens if you stop paying.
