EAN-13 Barcode Generator

Generate EAN-13 barcode SVG previews and calculate the checksum digit from 12-digit product-code examples in your browser.

Barcode generation runs locally in your browser. No upload, storage, account, or third-party API is used.

12 or 13 digit EAN value

EAN-13 uses 12 data digits plus a checksum digit. Entering 12 digits calculates the final digit automatically.

EAN-13 barcode workflow tips

Use EAN-13 generation for barcode examples, product-data QA notes, and documentation where a 13-digit retail-style code is needed.

Calculate the check digit

Paste 12 digits and the tool calculates the final EAN-13 checksum digit before rendering the barcode.

Compare adjacent formats

Use UPC-A Barcode Generator for 12-digit UPC examples or Code 39 Barcode Generator for alphanumeric labels.

Keep product data local

The preview is generated from pasted digits only. It does not look up product ownership, GS1 records, prices, or live catalog data.

What this tool does

The EAN-13 Barcode Generator accepts 12 digits to calculate the final checksum digit, or 13 digits to verify an existing code, then renders a browser-local SVG barcode preview for examples, documentation, and QA mockups.

Common use cases

Generate a browser-local EAN-13 barcode SVG, calculate the checksum digit from 12 digits, or verify a pasted 13-digit example for documentation and QA mockups.

Use EAN-13 Barcode Generator when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.

How to use it

Enter 12 digits to calculate an EAN-13 checksum, or paste all 13 digits to verify the final digit.
Review the normalized EAN-13 value, checksum digit, and generated barcode preview.
Copy the SVG markup or download the SVG for documentation, product-data mockups, or test fixtures.

Example workflow

Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.

Privacy note

EAN-13 barcode generation runs locally in your browser. ClearUtils does not upload, store, fetch, or validate product data with external services.

FAQ

Can this calculate an EAN-13 check digit?

Yes. Enter 12 digits and the tool calculates the thirteenth checksum digit before rendering the barcode preview.

Does this look up real product data?

No. It only renders a barcode from digits you type. It does not query product databases, GS1 records, prices, or ownership information.

Is my product code uploaded?

No. EAN-13 barcode generation runs locally in your browser and does not upload, store, fetch, or log your input.
