Online Tool Store
QR Code Reader
Decode QR codes from an uploaded photo or screenshot directly in your browser — copy the text or open the link, with nothing ever uploaded.
This works right here on your device — nothing gets sent out.
Nothing is uploaded — the image is decoded entirely on your device.
Decoded content
How the QR code reader works
- Choose an image containing a QR code — a screenshot, photo, or saved image.
- The tool draws the image onto an in-memory canvas and scans the pixel data for a QR pattern.
- The decoded text appears instantly — copy it, or open it directly if it’s a link.
How QR decoding works
A QR code encodes data as a grid of black and white modules, with three distinctive corner squares that let a scanner find the code’s position and orientation even if it’s rotated or tilted. Once located, the grid is sampled to recover a stream of bits, which is then decoded (with built-in error correction) back into the original text.
FAQ
What kinds of QR codes can this read?
Any standard QR code — links, plain text, Wi-Fi credentials, contact cards (vCard), and more. The tool decodes the raw content; interpreting a special format like Wi-Fi credentials is up to you or the app you paste it into.
Why didn’t it find a QR code in my image?
Make sure the code is in focus, well-lit, and not too small in the photo — a QR code that only takes up a tiny corner of a large photo can be harder to detect. Cropping the photo closer to the code often helps.
Does it automatically open links it finds?
No. If the decoded content looks like a web address, an “Open link” button appears so you can choose to open it yourself — nothing opens automatically.
Is my QR code image uploaded anywhere?
No. Decoding happens entirely in your browser using WebAssembly-free JavaScript — the image never leaves your device.
