How to make a QR code

Choose whether you are encoding a website address or plain text, type it in, and the code appears straight away. Pick colours if you like, check the "Encodes exactly" line to be sure it is right, then download a PNG for everyday use or an SVG for large prints.

Keep it easy to scan

  • Contrast matters. A dark pattern on a light background scans best. The tool warns you if the colours are too close.
  • Leave a margin. The quiet zone around the code helps scanners find it. Around four modules is a safe amount.
  • Size it for the distance. A poster seen from across a room needs a much larger code than a business card. SVG stays sharp at any size.
  • Always test it. Scan the finished image with a phone before you print or share it, especially after changing the colours.

What error correction does

QR codes can still be read even if part of the code is dirty or damaged, thanks to built-in error correction. A higher level survives more damage but makes the pattern denser. Medium is a good default; use High if the code might get scuffed, for example on a sticker or a sign.

Private by design

Everything here happens in your browser. The link or text you enter is never sent to our server or any outside service, so it is safe to make codes for private pages. Your last settings are remembered on this device only.

Frequently asked questions

Is my text or link sent anywhere?

No. The QR code is created entirely in your browser using a built-in encoder. Nothing you type is sent to our server or any other service, so it is safe for private links.

What is the difference between PNG and SVG?

PNG is a normal image, good for most uses — choose 512 or 1024 pixels. SVG is a sharp vector file that stays crisp at any size, which is ideal for printing large, like on a poster or sign.

Will coloured QR codes still scan?

Usually, as long as the pattern is clearly darker than the background. If the contrast is too low, the tool warns you. Keep a dark code on a light background and leave a margin (quiet zone) around it.

What is the quiet zone?

It is the empty margin around the code. Scanners need it to find the code, so leaving about four modules of space is a safe choice. The tool includes it in the downloaded image.

Can it handle other languages?

Yes. The text is encoded as UTF-8, so Japanese, emoji and other characters work. The code shows exactly what will be encoded, so you can check before you download.

Should I always scan-test my code?

Yes. Before printing or sharing widely, scan the downloaded image with a phone to be sure it opens the right thing, especially if you changed the colours.
