A static QR code never expires — the data is baked in. A dynamic code based on a short link keeps working as long as that link is active, and you can repoint it any time.

Can I change the destination of a QR code after printing?

Only if the code points to a short link you control. Encode a urlik short link into the QR code, then edit the link later and every printed code updates automatically.

PNG or SVG — which should I download?

Use PNG for screens and everyday printing. Use SVG for large-format print or when you need to resize the code without losing sharpness.

What is the smallest a QR code can be?

Keep it at least 2 x 2 cm for close scanning, and scale up for distance. Higher error correction and shorter data both let a code stay reliable at smaller sizes.

How to Create a QR Code for Anything (Wi-Fi, vCard, Payments)

A QR code is a square barcode that a phone camera can read instantly. Point, scan, done — no typing a web address, no hunting for an app. That frictionless jump from the physical world to a digital destination is why QR codes are everywhere now: menus, posters, packaging, business cards and payment screens. The good news is that making one is free and takes about thirty seconds.

QR codes can hold more than links

Most people think a QR code is just a website link, but the format encodes plain text of any kind. That means a single generator can produce codes for many real-world tasks:

Link / URL — open a website, form or menu.
Wi-Fi — join a network by scanning, with no password typing.
Contact (vCard) — save someone's name, phone and email in one tap.
Email, phone, SMS — start a pre-filled message or call.
Location — drop a map pin at exact coordinates.
Payment — show bank or crypto details for a fast transfer.

Our QR code generator supports all of these — pick the type, fill the fields, and the correct payload is built for you.

How to create a QR code

Open the generator, choose the content type, and enter your data (a link, Wi-Fi name and password, contact details, and so on). A live preview updates as you type. Adjust the colors, size and error-correction level, then download the result as a PNG for print or an SVG for crisp scaling at any size. No sign-up, no watermark.

Customizing without breaking the scan

You can style a QR code with your brand colors, but two rules keep it scannable. First, keep strong contrast between the foreground and background — dark on light is safest. Second, keep the light "quiet zone" margin around the square. If you add a center logo, raise the error-correction level to H so the code still reads with part of it covered.

Static vs. dynamic QR codes

A static QR code encodes the destination directly — simple, permanent and free, but you cannot change where it points once it is printed. A dynamic QR code encodes a short link instead, so you can edit the destination later without reprinting. If your printed poster might ever point somewhere new, generate a short link first and make the QR code out of that.

Where QR codes shine

Restaurants swap paper menus for a scan. Shops put a code on packaging that opens setup instructions or a review page. Event organizers link to schedules and tickets. Freelancers add a vCard code to a business card so clients save their details instantly. And with a payment page, a market seller can accept a transfer just by showing a code.

Test before you print

Always scan your final QR code with more than one phone before committing it to print. Check it at the real display size — a code on a billboard needs to be far larger than one on a business card. A good rule of thumb is that the code's width should be at least one-tenth of the scanning distance.
