Image metadata

Put product identity inside the image. Nothing about it looks different.

The identity travels with the file, so a machine reading the picture can tell you which product it is. Helping an agent act on a specific product

Add product identity

Runs in your browser. The image does not leave it.

Inside the imageGTIN and Digital Link written in

No GTIN yet? GS1 UK issues GTINs in the UK, with the barcodes that carry them. Your own GTINs are recognised by retailers and marketplaces worldwide, and they're what the GS1 Digital Link on a passport is built from.

What gets written into the file

Every field is optional. Fill in what you have and it goes into the image as standard metadata, in a form other software already knows how to read.

Product name and brandWritten as the title and creator in an XMP packet, the metadata format most image software reads.
GTINWritten as a PLUS Product in Image entry, the published standard field for naming a product shown in a picture.
Digital LinkWhere a scan of the product resolves. Leave it empty and it is built from the GTIN on GS1's resolver at id.gs1.org.
Product URLThe page the product lives on, kept beside the Digital Link so a reader can find both.
PNG and JPEGProduct identity is added as standard metadata that compatible software can read. Any existing XMP packet is replaced. The image data itself is not re-encoded.

Image metadata questions

Does the picture change?No. Only the metadata around the image data changes, so it looks exactly as it did.
Is my image uploaded?No. It is read and rewritten in your browser, and you download the new file.
Do I need a GTIN?No. A GTIN is what makes the identity unambiguous, so add it if the product has one. Check it first
Will it survive being uploaded somewhere?Not always. Many platforms re-encode images and strip metadata on the way through. Upload the file where you need it, download what the platform serves back and run that through the image inspector to see what survived.
Why put identity in an image at all?Pictures get copied, shared and passed to software a long way from the page they came from. Identity inside the file lets whatever finds the picture tell which product it shows and where its record lives.
