Create scanner-ready barcodes and batch label sheets

Choose the symbology your scanner or business system expects, validate one value or a line-separated batch, tune bar width, height, margin, text, and colors, then export SVG or PNG locally.

Select the format required by the receiving system, validate the data, and export a scanner-ready vector or raster asset.

Quick answer

Select the exact one-dimensional barcode format required by the receiving scanner, enter one value or up to 12 line-separated values, and export a combined SVG or PNG sheet. AppHelp validates the data with the selected symbology and shows GTIN-style check-digit guidance for EAN-13, EAN-8, UPC-A, and ITF-14. It encodes identifiers but does not assign, register, or authorize UPC, EAN, GTIN, or GS1 numbers.

How to use

  1. 1. Confirm the required symbologyCheck the scanner, retailer, warehouse, library, laboratory, or packaging specification first. The same text encoded in the wrong barcode format may scan but still be rejected by the receiving system.
  2. 2. Enter one value or a batchUse Single barcode for one label or Batch sheet for one value per line. Load the selected format sample to understand its accepted character and length rules.
  3. 3. Validate data and check digitsFix every invalid row. For EAN-13, EAN-8, UPC-A, and ITF-14, review the calculated or supplied check digit before export.
  4. 4. Tune and test the labelKeep dark bars, a light plain background, adequate bar width and quiet zones, then export SVG for scalable production or PNG for common office and digital use. Test the final physical size with the target scanner.

Examples

EAN-13 retail code

Input
5901234123457
Output
A valid EAN-13 label with check digit 7

Code 128 asset tag

Input
APPHELP-2026-001
Output
A mixed letter-and-number Code 128 label

Batch label sheet

Input
One compatible value per line
Output
One combined SVG or PNG containing up to 12 generated barcodes

Common use cases

  • Generate internal inventory, asset, shelf, shipping, and logistics labels
  • Prepare EAN or UPC artwork from identifiers already assigned to products
  • Create ITF-14 carton labels and numeric Interleaved 2 of 5 codes
  • Build Code 39 or Code 93 labels for industrial and compatibility workflows
  • Produce a small batch sheet without uploading a CSV or list to a remote service
  • Prototype barcode dimensions and human-readable captions before production

Edge cases

  • Generating an EAN, UPC, GTIN, or GS1-shaped barcode does not create ownership, registration, uniqueness, or retailer acceptance for its number.
  • EAN-13, EAN-8, UPC-A, and ITF-14 use strict lengths and check digits; a visually rendered code can still be wrong for a business database.
  • Code 39 is less dense than Code 128, so the same information often produces a physically wider label.
  • Interleaved 2 of 5 requires an even count of numeric digits, while Pharmacode accepts only a bounded integer range.
  • The on-screen preview is not a substitute for testing the final printer, material, surface, scanner, distance, and application settings.
  • Reducing margins, using colored or light bars, stretching artwork, or rasterizing at low resolution can make a valid value unscannable.
  • A human-readable text override changes only the printed caption, not the encoded barcode data.

Frequently asked questions

Which barcode format should I choose?
Use the exact format required by the receiving workflow. Code 128 is flexible for internal mixed-character identifiers; EAN and UPC are retail formats; ITF-14 is common on trade cartons; other formats serve specific legacy or industry systems.
Does this tool give me a UPC, EAN, GTIN, or GS1 number?
No. It only renders the value you provide. Obtain and manage identifiers through the organization, registry, marketplace, or business process that governs your products.
What is a barcode check digit?
It is a digit calculated from the preceding data digits and used to catch common scanning or typing errors. EAN-13, EAN-8, UPC-A, and ITF-14 include check-digit rules.
Can I generate several barcodes at once?
Yes. Choose Batch sheet and enter one compatible value per line. The interactive sheet renders and exports the first 12 non-empty rows together.
Should I download SVG or PNG?
SVG is preferable for scalable label design and print workflows because the bars remain sharp. PNG is convenient for office files and systems that require raster images, but it should not be enlarged after export.
Why does a valid barcode fail to scan after printing?
Common causes include narrow or blurred bars, insufficient quiet zones, poor contrast, scaling distortion, reflective or curved material, low printer resolution, and using a symbology the scanner is not configured to read.
Are my barcode values uploaded?
No. Validation, rendering, sheet composition, copying, and export happen locally in your browser.
