Read a QR code without an app

Sometimes a QR code is already in an image — a screenshot, a saved photo, a PDF page, or a poster you snapped. This reader decodes the code from that image and shows you exactly what it contains: a website link, Wi-Fi details, text, an email, or a phone number.

There is nothing to install. Upload, drag, or paste the image and the code is read on the spot, with a copy button for the result. If it is a link, you get a safe, clearly-labelled link you can choose to open.

How to read a QR code from an image

  1. Switch to Read. The reader is the second tab at the top of the tool.
  2. Add the image. Drop in a screenshot or photo, choose a file, or paste an image from your clipboard.
  3. See the result. The code's contents appear instantly — a link, text, Wi-Fi, and more.
  4. Copy or open. Copy the text, or open the link if you trust it.

Use a clear, well-lit image

For the most reliable read, use an image where the whole code is visible, in focus, and well lit, with a little margin around it. Very blurry, cropped, or heavily angled photos can be hard to decode — re-snap or re-crop if the first try fails.

Qué significa el texto decodificado

Cuando este lector decodifica un código te muestra la cadena almacenada sin procesar. Un prefijo inicial te indica para qué estaba pensado el código; así se leen los más comunes:

Si el resultado empieza por… …el código es
http:// or https:// un enlace de sitio web: se muestra aquí como un enlace clicable y claramente etiquetado que puedes elegir abrir.
WIFI: credenciales de Wi-Fi (nombre de la red, tipo de seguridad y contraseña) para unirse a una red.
mailto: un correo electrónico: una dirección, a menudo con asunto y cuerpo, pensada para abrir un borrador rellenado previamente.
tel: un número de teléfono para marcar.
SMSTO: or smsto: un mensaje de texto: un número y, a veces, un cuerpo de mensaje ya escrito.
(no prefix) texto sin formato: una nota, código o mensaje sin acción asociada.

Leer códigos de forma fiable

  • El lector decodifica toda la imagen a la vez, por lo que funciona con capturas de pantalla, fotos guardadas, páginas PDF exportadas como imágenes y escaneos, no solo tomas de cámara en vivo.
  • Trata un enlace decodificado con la misma precaución que cualquier enlace desconocido: la herramienta lo etiqueta claramente y nunca lo abre automáticamente, así que tú mantienes el control.
  • Si el resultado parece galimatías en lugar de un prefijo ordenado, puede que el código de origen esté dañado o solo capturado parcialmente: vuelve a fotografiarlo o recortarlo y léelo de nuevo.
  • Un resultado de Wi-Fi expone la contraseña de la red en texto plano, lo cual es normal en ese formato; solo ten cuidado con quién puede ver tu pantalla.

Preguntas frecuentes

How do I read a QR code from a picture?

Switch to Read, then drop in the picture, choose a file, or paste it. The code is decoded and its contents are shown with a copy button.

Do I need an app to read a QR code?

No. This reader runs in your browser on any device — phone, tablet, or computer — with nothing to install.

It says no code was found — why?

The image may be too blurry, too small, cropped, or badly lit. Use a clearer image where the whole code is visible and try again.

Where is my image processed?

Building or reading a QR code happens in your browser, so the file is created on your own device. How any data associated with the tool is handled is described in our privacy policy.
