Create downloadable barcodes for product packaging, cartons, warehouse labels and internal tracking. Choose from supported formats including ITF-14, Code 128, EAN-13, UPC-A, GS1-128, QR Code and Data Matrix, then download the result as a PNG or SVG file.
Explore free calculators, templates and practical tools built to help food businesses understand pricing, profitability, forecasting and day-to-day operations.
The barcode generator converts the number or data you enter into a downloadable barcode image using the selected barcode format, scale, height and display settings.
Yes. The barcode generator is free to use and does not require an account or login.
The tool supports a range of linear and two-dimensional barcode formats, including ITF-14, Code 128, EAN-13, UPC-A, GS1-128, QR Code and Data Matrix. The available options are shown in the barcode type selector.
Linear barcodes store information across a sequence of vertical bars and generally contain a shorter identifier. Two-dimensional barcodes such as QR Code and Data Matrix can store more information within a compact square or rectangular symbol.
Yes. Supported retail barcode formats include EAN-13 and UPC-A. You must enter a valid product identifier assigned for your business and market.
Yes. ITF-14 and other supported formats can be used for outer cartons and logistics units where appropriate. The correct format depends on the identifier, packaging level and requirements of the businesses receiving the product.
Yes. Formats such as Code 128 can be used to encode internally assigned product, location, batch or asset references. Internal codes should be managed consistently so each barcode identifies the intended record.
The tool can generate supported GS1 barcode symbologies from the identifier or structured data you enter. It does not issue GS1 company prefixes, GTINs or other identifiers.
You do not need a GS1 account to use the generator. However, businesses using GS1 identifiers for commercial products generally need valid numbers allocated through the appropriate GS1 member organisation or trading arrangement.
No. The generator creates an image from the data entered. It does not allocate GTINs, company prefixes or other globally unique product identifiers.
A Global Trade Item Number, or GTIN, is a unique identifier used for trade items. Depending on the packaging level and barcode format, a GTIN may contain 8, 12, 13 or 14 digits.
EAN-13 is a 13-digit retail barcode commonly used on consumer products. The barcode encodes a valid GTIN-13, including its check digit.
UPC-A is a 12-digit retail barcode commonly used in North America. It encodes a valid GTIN-12, including its check digit.
ITF-14 is a linear barcode commonly used to encode a 14-digit trade item number on outer packaging such as cartons and cases.
Code 128 is a compact linear barcode that can encode numbers, letters and other supported characters. It is commonly used for logistics, warehouse labels and internal tracking.
GS1-128 uses the Code 128 symbology with GS1 formatting rules and Application Identifiers. It can encode information such as product identifiers, batch numbers, expiry dates and logistics-unit references.
Data Matrix is a two-dimensional barcode capable of storing more information in a compact area than most linear barcodes. GS1 DataMatrix can be used for structured product and traceability data where supported by the receiving system.
Yes. Supported GS1 barcode formats can encode batch and expiry information using correctly structured GS1 Application Identifiers. The receiving scanner or system must also support and interpret that data.
GS1 Application Identifiers define the meaning and format of each piece of data encoded within a GS1 barcode. Examples include identifiers for a GTIN, batch or lot number, expiry date and serial number.
The generator may validate or calculate check digits for supported barcode types where the selected format permits it. You should still confirm that the underlying identifier is valid and correctly assigned before using the barcode commercially.
The entered data may not match the length, character or check-digit requirements of the selected barcode type. Confirm that the value is valid for that format and remove unsupported spaces or characters.
Yes. Use the human-readable text option to choose whether the encoded value is displayed beneath supported linear barcodes.
Scale changes the rendered size and resolution of the barcode. Increasing the scale generally creates a wider image with more pixels, which can be useful for larger labels or higher-resolution printing.
Height adjusts the vertical size of supported linear barcodes. It does not change the information encoded in the symbol.
Yes. Generated barcodes can be downloaded in the supported file formats available within the generator.
PNG is convenient for documents, websites and basic printing. SVG is a scalable vector format that can be resized without losing sharpness, making it better suited to many packaging and professional design workflows.
Yes, provided the encoded identifier is valid, the selected barcode format is appropriate and the final printed symbol meets the size, contrast, quiet-zone and print-quality requirements of the relevant retailer, trading partner or standard.
Not necessarily. Scanner compatibility depends on the barcode format, encoded data, print size, contrast, resolution, surface, scanning distance and the scanner configuration. Test the final printed barcode using the equipment and workflow in which it will be used.
Barcodes require blank space around the symbol, commonly called a quiet zone, so scanners can distinguish the barcode from nearby text, borders and graphics.
No. Successful scanning also depends on the validity of the encoded data, final print dimensions, quiet zones, colour contrast, printer quality, packaging material and scanner compatibility.
Yes. Test the barcode at its final printed size and on the intended packaging material before committing to a full production run. Where commercial compliance is required, arrange appropriate barcode verification.
No. Barcode generation is completed locally within your browser, and the values entered into the generator are not sent to Supply'd servers.
Yes. Supply'd ERP can generate product, batch, carton and logistics labels using connected product, inventory, production and order information.
Yes. Supply'd ERP supports compatible barcode scanners across receiving, stock movements, stocktakes, production, picking, packing, dispatch and delivery workflows.
