# QR code generator

> A free, no-signup QR designer — custom colours, logos and frames, exported as PNG or SVG.

The free QR generator at
[trackrev.io/tools/qr-code-generator](https://www.trackrev.io/tools/qr-code-generator) creates
branded QR codes entirely in your browser — no signup, no watermark, and codes that never expire.

## Design and export

<Steps>
  <Step title="Enter your link or text">
    Paste any URL (or plain text) to encode.
  </Step>

  <Step title="Style it">
    Set colours or a gradient, choose a dot pattern and corner style, add a logo, and optionally a
    frame with a call-to-action.
  </Step>

  <Step title="Export">
    Download as **PNG** (256 / 512 / 1024 / 2048 px) or **SVG** (vector), or copy the SVG.
  </Step>
</Steps>

## PNG vs SVG

* **PNG** — a raster image; pick a large size (1024+) for print.
* **SVG** — vector; scales to any size without losing quality. Best for print and large formats.

## Error correction

Higher error correction makes a code scannable even when partly obscured (e.g. by a logo), at the
cost of density:

| Level | Recovers | Use                            |
| ----- | -------- | ------------------------------ |
| L     | 7%       | Clean digital use              |
| M     | 15%      | General purpose                |
| Q     | 25%      | Default; some obstruction      |
| H     | 30%      | Logos, print, rough conditions |

<Tip>
  For QR codes you want to **track**, generate them from a
  [TrackRev tracking link](/link-tracking/qr-codes) instead of this free tool — then every scan is
  recorded with geo, device and (with revenue connected) attribution.
