QR Code Generator / QR Guide
QR Code Generator Guide
This hub is built for practical QR work, not just for generating a code and moving on. It starts with what QR codes are and how to scan them on a phone, then helps you choose what the code should contain, handle Wi-Fi QR more carefully, and pick the right export format for the final destination.
Use it when you want the QR code itself and the surrounding workflow to feel more deliberate.
Where to start
Pick the entry point that matches your current question.
You want the QR basics first
Start with What QR codes are if you want a simple model before you choose between URL, Text, and Wi-Fi QR types.
You want the phone-scanning basics first
Start with How to scan QR codes on a phone if you want the default iPhone / Android camera workflow before you generate anything else.
You are choosing the QR type
Start with the URL vs Text vs Wi-Fi guide and match the code to the action after the scan.
You are about to share network access
Start with the Wi-Fi safety guide so you check the sharing scope and setup details first.
You are exporting for slides or print
Start with the PNG vs SVG guide so the file format matches the final workflow.
Choose by the scan result
A QR code is useful only when the action after the scan is clear.
Print or signage
Use a URL QR code and prefer SVG when the design will be resized. Test the final print size and keep enough quiet zone around the code.
Wi-Fi access
Use a guest network when possible, verify the SSID, security type, and password, and avoid posting access to the main private network.
Handouts or shared notes
Avoid packing long text into the code. If the content may change, link to a page you can update instead of freezing the full text inside the QR code.
Checks before you share it
Generation is only the first step; the real test is whether people can scan it in context.
Scan on another device
A code that works on your own phone may still depend on a logged-in session or cached page. Test it on a separate phone before publishing.
Keep the printed size stable
Shrinking the code or cropping its margin can break scanning. Test at the final size, especially on flyers, labels, and slides.
Label the destination
A standalone QR code does not tell people where it leads. Add visible text such as menu, survey, Wi-Fi, or event map next to it.
Articles
Choose the article that matches whether you are still learning the basics, deciding what the code should contain, or preparing for print and sharing.

A beginner guide to what QR codes are, what happens after a scan, how URL, Text, and Wi-Fi codes differ, and why long content or tiny print can hurt scan reliability.
How to scan QR codes on a phone
A beginner guide to scanning QR codes on iPhone and Android with the default camera, including basic checks for light, distance, focus, framing, and Wi-Fi QR differences.
When to use URL, Text, or Wi-Fi QR codes
Learn when to choose a URL QR code, a text QR code, or a Wi-Fi QR code for posters, handouts, guest access, and other practical use cases.
Safe Wi-Fi QR setup and common failure points
A practical guide to creating Wi-Fi QR codes safely, checking SSID and security settings, and avoiding the most common scan and connection issues.
PNG vs SVG for printing and sharing QR codes
A practical comparison of PNG and SVG for QR codes, including when to use each for slides, handouts, print, and design-tool workflows.
Test the decision in the tool
Once you know the right mode and export format, generate one real QR code and check it in the same environment where people will scan it.
