Why you might need to create a QR code
A QR code has become a fast way to share a link, WhatsApp number, or contact info without anyone typing anything by hand — just scan the code with a camera. Whether it's for your business, a restaurant menu, or a business card, creating a custom QR code saves time and makes it easier for people to reach the information.
How a QR code keeps working even if part of it gets damaged or covered
A QR code is designed with a feature called "error correction" that lets it keep working even if part of it gets damaged or covered, for example with a logo. The system adds redundant data inside the code itself, and there are 4 error correction levels that differ in how much data can be lost while the code stays readable — from the lowest level (about 7%) to the highest (about 30%). That's why you can place a small logo in the center of the code, or even if a small part gets scratched or faded, a scanner will still be able to read it correctly.

Practical tips before you start
Before creating and using your code, keep these points in mind:
- If you'll place a logo or image in the center of the code, choose a higher error correction level so the code stays readable.
- Test the code with a real phone camera before printing it or publishing it widely.
- If you'll print the code very small, keep the color contrast (usually black and white) clear so it stays easy to scan.
- If you need to update the link the code points to after publishing, use a dynamic QR code instead of a static one if the tool offers it.
Since the tool works without any sign-up and without permanently storing your data, there's no need to worry about your privacy.
Common use cases
- Adding a QR code to a business card that links directly to your website or social accounts.
- Printing a code on a restaurant menu that links to an online menu instead of a printed one.
- Sharing a Wi-Fi link with guests with one scan instead of typing the password manually.
- Linking a physical product to its details page or a how-to-use video.

Frequently asked questions
Does a QR code work without internet?
The code itself opens with the camera without internet, but if it leads to a link, you'll need an internet connection to open it.
Is the QR Code Generator tool completely free?
Yes, you can use it for free with no limit on how many times you use it.
Is the code's data stored with you?
No, generating the code happens only to complete your request, with no sign-up and no permanent storage of your data.
Can I place a logo or image in the center of the code?
Yes, thanks to the error correction feature built into the QR code design, you can place a small logo in the center without breaking the code.
Does the code's size affect how scannable it is?
Yes, a code that's too small can be hard to scan from a distance, so choose a suitable size depending on where you'll use it (card, sign, menu).
Can I generate a QR code for a WhatsApp number that opens a chat directly?
Yes, you can create a code with a direct WhatsApp link, and scanning it will open a ready-made chat with that number instantly.
