## What does this tool do?

QR Code Generator turns any text or URL into a QR code — the two-dimensional
barcode that phones scan with their camera. Type or paste your content, choose
an error correction level, and download the result as a **clean SVG or PNG**.

Everything happens **in your browser**. The content you type is encoded locally
and never uploaded, and the download has **no watermark, no logo and no
tracking**.

## Why no watermark and no tracking matters

Most QR generators watermark the PNG or gate the download behind an email. This
one doesn't. The QR you download is exactly what your scanner sees: a clean
black-on-white matrix with the standard quiet zone. Nothing is injected, and no
network request is made while generating.

## Error correction levels

A QR code embeds redundant data so it can still be read if part of it is
damaged or covered. You choose how much redundancy to add:

| Level | Recovery | Use it when |
| --- | --- | --- |
| **L** | ~7 % | Maximum data density, clean printing, controlled conditions |
| **M** | ~15 % | Good default for screens and general use |
| **Q** | ~25 % | Codes that may get dirty or partially covered |
| **H** | ~30 % | Logos overlaid on the code, harsh environments |

More recovery means a denser, larger code for the same content. If the content
doesn't fit at the level you picked, lower the level (for example from H to M).

## The quiet zone

Every QR code needs a **quiet zone**: a clear margin around the matrix, at
least **4 modules** wide, so scanners can tell where the code starts and ends.
This tool includes the 4-module quiet zone automatically in both the SVG and
the PNG.

## How much fits in a QR code

Capacity depends on the content and the error correction level. A QR code has
40 sizes ("versions"); the largest (version 40) holds at most about **2,900
bytes** of arbitrary data. Plain text and URLs encode more efficiently than
random binary content, and numbers encode more efficiently still.

For a URL or a short text you will almost never hit the limit. If your content
is too long, shorten it or lower the error correction level.

## Content formats that just work

You can encode any string. Common formats are just text written in a standard
way — no special mode is needed:

- **URL** — `https://example.com/page`
- **Email** — `mailto:hello@example.com?subject=Hi`
- **Phone** — `tel:+34600123456`
- **SMS** — `SMSTO:+34600123456:Hello`
- **Wi-Fi** — `WIFI:T:WPA;S:NetworkName;P:Password;;`
- **Contact (vCard)** — a `BEGIN:VCARD … END:VCARD` block

Paste any of these exactly as shown and the result will open the right app when
scanned.

## What this tool does not do

No dynamic QR codes, no scan analytics, no account, no logo uploads. It
produces a static QR code from your content and nothing else. Scan carefully:
like any QR code, a code that encodes a link will open that link on the phone
that scans it.
