The toolkit
All scanner tools
Eight tools, one decoder. Each opens with the scanner in the first viewport.
Scanner QR
Scannez un code QR avec la caméra, une capture d’écran ou une image. Le décodage se fait dans votre navigateur : rien n’est envoyé, rien n’est installé, aucun compte n’est requis.

Scanner de codes-barres
Lisez les codes-barres EAN-13, EAN-8, UPC-A, Code 128 et Data Matrix via la caméra ou une image. Nous vérifions la clé de contrôle et affichons les champs GS1.
EAN-13 · EAN-8 · UPC-A · UPC-E
Image / capture
The code is not in front of your camera but inside a screenshot, a photo or a PDF? Drop the file here — decoding happens in your browser, not on a server.

EAN / UPC Scanner
Scan a product code, verify the check digit, place the registration prefix. The scanner tells you whether a GTIN can be genuine at all.
EAN-13 · EAN-8 · UPC-A · UPC-E
GS1 DataMatrix
Industrial codes carry more than a number: batch, expiry, serial, quantity. The scanner breaks the GS1 payload down into application identifiers.

Accès Wi-Fi
A Wi-Fi code contains the SSID, encryption type and password in the WIFI: format. The scanner separates the fields — useful when the label is gone.
WIFI: · WPA/WPA2/WPA3 · hidden SSID
Carte de contact
Digital business cards live inside QR codes. The scanner extracts name, organisation, phone, email and website into copyable fields.
vCard 2.1/3.0/4.0 · MECARD · BIZCARD
Vérification de sécurité
QR codes are invisible links. The scanner shows the destination before you click — and flags the patterns quishing relies on.

The network logic
Scanning is one half. The other is creation: QR codes for Wi-Fi, vCard, SEPA and links live on qrcodeerstellung.de, barcode symbologies on barcode.qrcodeerstellung.de, and print-ready logistics labels with VDA 4902, KLT and MAT on label.qrcodeerstellung.de.
All three share one rule: the tool comes before the explanation. This page links straight to the tools, never to marketing pages.
