Scan a QR code without an app

No download, no account. Semacode reads QR codes straight in your browser – with your camera live, or from a photo or screenshot you upload.

Scan it nowHow it works
Nothing is uploaded – it all runs on your device.

No install needed – three steps

Open it in your browser

Just open Semacode, on phone or computer. Nothing to install.

Camera or image

Point your camera at the code, or upload a photo or screenshot if the code is already an image.

Read & open

Semacode decodes it locally and shows the link or content to open or copy.

Why no app is better

Nothing to install

No download, no permissions to grant, no account – open a page and you're scanning.

Private by default

Decoding runs on your device; nothing is uploaded unless you choose to.

Camera or upload

Live camera when the code is in front of you, image upload when it's already a picture.

Frequently asked questions

Can I really scan a QR code with no app?
Yes. Modern browsers can use your camera and decode images directly, so a web page is all you need – no app store, no install.
Doesn't my phone's built-in camera already do this?
Often it does – but it fails on codes that are only an image (screenshots, PDFs) or that are damaged. A browser tool handles those cases too.
Is it free?
Yes, completely free and no signup for reading a code.
Does it work on a computer?
Yes – upload an image, or use a webcam. Same tool, no install.
