10 focused utilities

Start with a product identifier, then validate, structure and encode it without sending the value to our servers.

01

GTIN & product identifiers

GTIN ValidatorCheck format, length and the GS1 modulo-10 check digit.GTIN Check Digit CalculatorCalculate the final digit for GTIN-8, GTIN-12, GTIN-13 or GTIN-14.GTIN NormalizerValidate a GTIN and express it in fixed 14-digit form.UPC to GTIN ConverterValidate UPC-A / GTIN-12 and produce its 14-digit representation.EAN to GTIN ConverterValidate EAN-8 or EAN-13 and produce its GTIN-14 representation.
02

GS1 Digital Link

GS1 Digital Link GeneratorBuild a standards-grounded link from common trade-item data.GS1 Digital Link ValidatorValidate URI syntax and the GS1 data encoded in a link.GS1 Digital Link DecoderInspect identifiers, qualifiers, attributes and URI extensions.
03

Barcode / QR

GS1 QR Code GeneratorCreate local SVG and PNG QR output from a valid Digital Link.
04

GS1 data parsing

GS1 Application Identifier ParserParse bracketed, element-string and scanner GS1 AI data.

A practical data path

From identifier to connected product

  1. 01Validate

    Check length, characters and check digits before data moves downstream.

  2. 02Structure

    Organize identifiers and attributes with GS1 Application Identifiers.

  3. 03Link

    Express product identity and qualifying data in a GS1 Digital Link URI.

  4. 04Encode

    Generate a QR code locally for testing and implementation workflows.

Why ProductPassKit

Clear technical utilities, without a platform tax

01

Immediate

Use every v1 tool without an account, workspace or onboarding flow.

02

Private by design

Core processing happens locally in your browser. Raw identifiers are excluded from analytics.

03

Precise about limits

Syntax validity is separated from ownership, resolver and print-quality claims.

04

Built for the next step

The toolkit connects today’s product identifiers to future Digital Product Passport workflows.

Digital Product Passport direction

Identity is the anchor. Product data is the journey.

ProductPassKit is being built to bridge reliable product identifiers, web-resolvable links and 2D data carriers with future Digital Product Passport workflows. The current tools support that foundation; they do not claim DPP compliance or certification.
