QR Code Reader / Decoder

Decode any QR code image directly in your browser. Drop a screenshot, photo, or saved image into the uploader and the tool returns the embedded text, URL, Wi-Fi credentials, contact card, or other payload — instantly and without sending the image anywhere.

Cara Penggunaan

Click the upload area and select an image containing a QR code (PNG, JPG, WEBP, GIF, or BMP).
The decoded content appears in the result box within a fraction of a second.
Check the “Detected type” badge — the tool recognises URLs, Wi-Fi configs, vCard / MeCard contacts, mailto, tel, SMS, geo coordinates, and otpauth links.
Use the Copy or Download button to keep the raw decoded payload.

Fitur

Sepenuhnya sisi klien – the image never leaves your device; decoding runs in your browser via canvas.
Smart payload parser – splits Wi-Fi, vCard, MeCard, mailto, tel, SMS, geo, and otpauth payloads into named fields.
Robust decoder – tries both normal and inverted images, handling dark-on-light and light-on-dark QR codes.
Salin & unduh – one click to copy the decoded text or save it as a plain-text file.
No account required – no signup, no rate limit, no credits consumed.

Common QR Payload Types

URL – Most common; opens a website when scanned.
Wi-Fi – Encodes SSID, password, and auth type so phones can join networks automatically.
vCard / MeCard – Stores a contact’s name, phone, email, and organisation.
otpauth – Used by authenticator apps to provision TOTP / HOTP secrets.
Geo – Latitude / longitude coordinates that open in a maps app.

 Tanya Jawab Umum

How does a QR code actually store data?

A QR (Quick Response) code is a 2D matrix barcode invented by Denso Wave in 1994. Black-and-white modules encode binary data using Reed-Solomon error correction, which lets the code remain readable even if up to 30% of it is damaged or obscured. The three large square "finder" patterns in the corners let a decoder locate and orient the code regardless of rotation.
What are the different QR code error correction levels?

QR codes support four error correction levels: L (~7% recovery), M (~15%), Q (~25%), and H (~30%). Higher levels mean more redundancy and a denser code, but greater tolerance for dirt, smudges, or logos placed over the design. The level is encoded in the format information stored around the finder patterns.
Why does the same payload sometimes produce a different-looking QR code?

QR codes apply one of eight mask patterns to make the black-and-white distribution as balanced as possible, which helps scanners. The encoder picks whichever mask scores best for the specific payload. Two encoders may pick different masks for identical input, producing visually distinct but equally valid codes.
Are QR codes inherently safe to scan?

The QR code itself is just data; the risk lies in what the payload tells your phone to do. URLs can lead to phishing sites, Wi-Fi blocks can connect you to a malicious access point, and otpauth links could be planted to mislead you. Always preview the decoded content (as this tool shows) before tapping or trusting it.
