The toolkit
All scanner tools
Eight tools, one decoder. Each opens with the scanner in the first viewport.
Leitor QR
Leia um código QR com a câmera, um print ou uma imagem. A decodificação acontece no navegador: nada é enviado, nada é instalado e você não precisa de conta.
QR Code · Micro QR · Aztec
Leitor de código de barras
Leia códigos de barras EAN-13, EAN-8, UPC-A, Code 128 e Data Matrix pela câmera ou imagem. Validamos o dígito verificador e mostramos os campos GS1.
EAN-13 · EAN-8 · UPC-A · UPC-E
Imagem / print
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.
PNG · JPG · WebP · GIF
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.

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
Contato
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
Verificação de segurança
QR codes are invisible links. The scanner shows the destination before you click — and flags the patterns quishing relies on.
URL · quishing heuristics · punycode
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.
