Free barcode tools for Code 128, Code 39, Code 93, UPC/EAN, GS1-128, ITF, Data Matrix, PDF417, Aztec, check digits, labels, bulk output and scanning.

Primary barcode workflows

Start with the eight flagship barcode tools

Choose the required symbology, verify identifier arithmetic, then confirm print or scan readiness. Specialist formats, bulk generation, labels and size calculators remain available below when the workflow genuinely changes.

Identifier boundary: a mathematically valid or visually rendered barcode is not proof that a GTIN, UPC, EAN or GS1 number was officially assigned to the product or organization.

Choose → encode → validate → size → export → scan-test

Start with the receiving system and data contract. Generate the exact symbology, preserve readable dimensions and quiet zones, export the final artwork, and scan-test that final version before bulk use.

Choose the symbology

Use the format the receiving system expects; similar-looking barcodes are not interchangeable.

Barcode GeneratorEnter the value and choose the barcode type. The preview updates immediately; export first, then open print and style settings only when you need physical-size or appearance controls.Code 128 Barcode GeneratorType a SKU, serial number, shipping ID, or other Code 128 value and see the barcode immediately. Styling and print geometry stay in optional settings below the preview.Code 39 Barcode GeneratorCreate a Code 39 barcode with live validation and export it as SVG or PNG.Code 93 Barcode GeneratorCreate Code 93 locally, choose standard or Full ASCII input, control print sizing, and export PNG or SVG.Codabar Barcode GeneratorEnter Codabar data with A-D start and stop characters, validate it, and export SVG or PNG.Interleaved 2 of 5 Barcode GeneratorValidate numeric ITF data, render the barcode locally, and export SVG or PNG.

Retail and GS1 tools

Validate check digits and use the exact UPC/EAN/GTIN or GS1-128 format required by the destination workflow.

UPC Barcode GeneratorEnter an 11-digit body to append the check digit or a complete 12-digit UPC-A to verify it. Rendering does not assign an official GTIN/UPC.UPC-E Barcode GeneratorCreate UPC-E locally from 7 digits or validate a complete 8-digit code, inspect the expanded UPC-A value, and export PNG or SVG.EAN-13 Barcode GeneratorEnter a 12-digit body to append the check digit or a complete 13-digit value to verify it. Rendering does not assign an official GTIN.EAN-8 Barcode GeneratorCalculate the EAN-8 check digit and export the resulting barcode as SVG or PNG.ITF-14 Barcode GeneratorCalculate the GTIN-14 check digit and render an ITF-14 barcode locally.GS1-128 Barcode GeneratorEnter GS1 application identifiers and values manually, inspect the parsed AI count, then render and export a GS1-128 barcode locally.ISBN Barcode GeneratorConvert a valid ISBN-10 to ISBN-13 when needed, verify the check digit, and render an EAN-13 barcode.Barcode Check Digit CalculatorChoose an identifier length and calculate or verify its final check digit in the browser.Barcode Number ValidatorUse validation as a syntax/check-digit gate, not as proof that an identifier is registered, assigned, active, or accepted by a specific retailer or logistics network.

2D and stacked codes

Use Data Matrix, PDF417, or Aztec only when the receiving system explicitly expects that 2D symbology.

Data Matrix GeneratorCreate a local Data Matrix barcode, inspect its rendered size, self-test it when the browser supports Data Matrix detection, and download PNG or SVG.PDF417 GeneratorCreate a local PDF417 symbol with a browser-side encoder, inspect dimensions, self-test when supported, and download PNG or SVG without a WebToolArc barcode API.Aztec Code GeneratorCreate an Aztec Code locally from supplied data, control scale and padding, and export PNG or SVG without a WebToolArc barcode API.

Bulk, labels & sizing

Generate batches, label sheets and output dimensions after the identifier/symbology choice is settled.

Bulk Barcode GeneratorPaste Label | Value rows or import a file, review successful and failed rows immediately, then download the SVG batch or print the grid. Batch settings stay out of the first-use path.Bulk Data Matrix GeneratorPaste identifiers or upload a CSV/TXT file, create Data Matrix symbols in the browser, preview the batch and download PNG/SVG files with a manifest ZIP.Barcode Label GeneratorEnter label and barcode pairs and see the label sheet update as you type. Print or save PDF from the preview; change columns, format, or height only when the job needs it.Barcode Size CalculatorEnter barcode data and print assumptions to compare millimeters, inches, pixels, and the encoded value before committing to a label size.

Scan & verify

Decode the final artwork and inspect the detected format/value before production or handoff.

Barcode ScannerDecode locally when the browser or client-side fallback supports the symbology; scan success does not prove that a product or logistics identifier was officially assigned.
