Frequently Asked Questions
The generator creates QR codes based on the information you enter, including text, URLs, emails, phone numbers, locations, Wi-Fi credentials, calendar events, or business card details
Yes, you can choose foreground and background colors and specify the pixel size before generating the QR code.
You can download your QR code as PNG, JPEG, SVG, or EPS. Note: EPS may need external conversion from SVG.
Click the “Copy Embed Code” button to copy an HTML snippet with your QR code in base64 format.
Error Correction Level in QR codes refers to how much of the code can still be read accurately even if it gets damaged, dirty, or partially covered. QR codes use a system called Reed–Solomon error correction that allows them to recover missing data. There are four levels of error correction: L (Low), M (Medium), Q (Quartile), and H (High).
– Level L can recover about 7% of lost data and is suitable when the QR code will remain clean and you need to store as much information as possible.
– Level M can recover around 15% of data and is the most commonly used, offering a good balance between data capacity and reliability.
– Level Q restores roughly 25% and is useful when the code might be printed on uneven or slightly damaged surfaces.
– Level H offers the highest protection, recovering up to 30% of data, and is ideal when you’re placing a logo inside the QR code or printing it in environments where damage is likely.
In short, use Q or H for better durability in print or outdoor use, and M for standard digital or general.
The “Copy Embed Code” option lets you easily add your generated QR code to any website or blog without needing to upload the image manually. When you click this button, it copies a small piece of HTML code (called an embed code) to your clipboard. This code usually looks like:
<img src="data:image/png;base64,..." alt="QR Code">
You can then paste this code directly into your webpage’s HTML — for example, inside a blog post, sidebar, or contact page.
“Copy Embed Code” is the easiest way to display your QR code online instantly — no need to upload files or link to external images.
These two options are related to how your Wi-Fi network is configured and how your QR code should store that information.
1. Hidden Network:
A hidden network is a Wi-Fi network that does not broadcast its SSID (name) publicly. Normally, nearby devices can see a list of all available Wi-Fi networks — but if the network is hidden, its name won’t appear there.
– When to check this option:
If your Wi-Fi network is hidden, you must check this box so the QR code includes that information. Otherwise, the device scanning your QR code won’t be able to connect automatically.
2. Unencrypted / No Password:
This option is for open Wi-Fi networks that don’t have a password — meaning anyone can connect without entering one.
– When to check this option:
If your Wi-Fi network doesn’t require a password (no encryption), select this option. The QR code will then be generated without a password field.
Note: Using open (unencrypted) Wi-Fi networks is not recommended because they are insecure — anyone nearby can connect and potentially monitor your traffic. Always prefer encrypted connections (like WPA2 or WPA3) when possible.
