FAQ
How do I decode an e-invoice QR for free?
Paste the QR string and this page reads its JSON payload — seller and buyer GSTIN, document number and date, total value, item count, main HSN code and the IRN — on your device with no upload.
Is it safe to paste an e-invoice QR here?
Yes. The QR carries business and tax details, so it is decoded entirely in your browser and nothing is transmitted or stored, which you can verify by turning off your Wi-Fi.
Does it verify the IRP signature?
No. It decodes the payload for reading; it does not have the IRP public key and does not verify the signature, so treat the contents as unverified.
What is the IRN?
The Invoice Reference Number is the unique identifier the Invoice Registration Portal assigns to a registered e-invoice, included in the QR.
Limits
Decodes the QR payload fields; it does not validate the signature or cross-check the IRN with the portal.
