Are the QR codes generated here free?

Yes, all QR codes generated on this site are completely free. There are no limits on the number of QR codes you can create, and they never expire. Static QR codes work forever.

What is error correction in QR codes?

Error correction allows a QR code to be read even if part of it is damaged or obscured. There are four levels: L (7% recovery), M (15% recovery), Q (25% recovery), and H (30% recovery). Higher levels make the QR code more robust but also larger.

What data types can I encode in a QR code?

You can encode URLs, plain text, email addresses (mailto), phone numbers (tel), SMS messages, WiFi network credentials, and vCard contact information. Each type uses a specific format that devices can automatically recognize.

What is the difference between SVG and PNG QR codes?

SVG (Scalable Vector Graphics) QR codes can be scaled to any size without losing quality, making them ideal for print. PNG (bitmap) QR codes have fixed resolution but are universally supported. For most uses, SVG is recommended.

Static QR codes like the ones generated here never expire. The data is encoded directly in the pattern, so as long as the QR code image exists and the destination (like a URL) is active, it will always work.

Frequently Asked Questions

What is a QR code? ▼

A QR (Quick Response) code is a two-dimensional barcode that stores information like URLs, text, contact details, or WiFi credentials. It can be scanned by smartphone cameras to quickly access the encoded data. QR codes were invented in 1994 by Denso Wave for tracking automotive parts and have since become ubiquitous.

Are the QR codes free? ▼

Yes, all QR codes generated here are completely free with no limits. Static QR codes encode data directly in the pattern and never expire. You can generate as many as you need for personal or commercial use.

What is error correction? ▼

Error correction allows a QR code to remain scannable even if part of it is damaged. Level L recovers 7% of data, M recovers 15%, Q recovers 25%, and H recovers 30%. Higher levels produce larger QR codes but are more resilient. Use H if you plan to add a logo overlay.

What data types can I encode? ▼

This tool supports URLs, plain text, email addresses (opens email client with pre-filled fields), phone numbers (initiates a call), SMS messages, WiFi network credentials (auto-connects on Android), and vCard contact cards (adds to phone contacts).

SVG vs BMP — which should I use? ▼

SVG is a vector format that scales to any size without losing quality — ideal for print materials, websites, and professional use. BMP is a bitmap format with fixed resolution. For most purposes, SVG is the better choice.

Do QR codes expire? ▼

Static QR codes never expire. The data is encoded directly in the pattern, so the QR code will always work as long as the image is intact and the encoded destination (like a URL) remains active.
