  2. 2.Optionally pick an error-correction level (M is fine for most uses; H for logos or small prints) and an output size.
  3. 3.Click Download PNG to save the code, then print or share it. Your text never leaves your browser.

About QR Code Generator

A QR code generator turns any piece of text — a web address, a Wi-Fi password, a phone number, a vCard contact — into the familiar black-and-white square that any phone camera can read in a second. This one generates the code the instant you start typing and lets you download it as a crisp PNG, and it does all of that without ever sending your text to a server.

What you can encode. The most common use is a link: put a URL in the box and you get a QR code that opens it when scanned — perfect for posters, business cards, packaging, restaurant menus, and event flyers. But a QR code is just text, so you can also encode a Wi-Fi login (guests scan to join your network without typing the password), a vCard or MECARD contact so someone can save your details with one tap, an email or SMS pre-fill, a phone number, a payment link, or plain text such as a coupon code. Anything you can write, you can turn into a code.

What the error-correction level means. Every QR code stores redundant data so it still scans when part of it is dirty, scratched, or covered — for example by a logo placed in the middle. You choose how much redundancy: level L recovers about 7% of the code, M about 15%, Q about 25%, and H about 30%. Higher recovery makes the code more robust but also denser (more squares), so it needs to be printed larger or scanned from closer. M is the everyday default and what most generators use; step up to Q or H only for codes that will be printed small, placed on curved surfaces, or overlaid with a logo.

How much data fits. Capacity depends on the content type and the error-correction level. At the most forgiving settings a single QR code can hold roughly 7,089 numeric digits, 4,296 alphanumeric characters, or 2,953 bytes of binary data. In practice, keep URLs short: the more characters you encode, the denser the grid and the harder it is for an old or low-resolution camera to read. If a long link won't scan reliably, shorten it first or drop to a lower error-correction level.

Why generating in the browser is more private. Many free QR sites route your data through their servers, and some generate a redirect link they control — meaning they can log every scan, change the destination later, or let the code expire. Because this tool runs entirely as client-side JavaScript, your text never leaves your device, the QR code encodes your destination directly (no tracking redirect), and it will never expire or break. There is no account, no watermark, and no limit on how many codes you make.

Tips for reliable scanning. Keep a quiet margin (white border) around the code — this tool adds one automatically. Print at high contrast: dark code on a light background scans best; avoid low-contrast color pairs. Test the printed code with more than one phone before you commit to a large print run. For a code that will carry a logo, choose error-correction level H so the overlay doesn't break it.

Frequently asked questions

Is this QR code generator free and unlimited?
Yes. It runs entirely in your browser, so there are no server costs, no sign-up, no watermark, and no limit on how many QR codes you can create or download.
Do my QR codes expire or track scans?
No. The code encodes your text or link directly — there is no tracking redirect and nothing on a server to expire. Once you download the PNG it works forever, offline included.
Which error-correction level should I choose?
Use M (about 15% recovery) for everyday links and posters. Choose Q or H (25–30% recovery) if the code will be printed small, placed on a curved surface, or overlaid with a logo, since higher levels stay scannable when part of the code is obscured.
