Frequently Asked Questions

What is a barcode generator?

A barcode generator is an online tool that converts text or numeric data into a scannable barcode image. Enter your data, choose a barcode format, and download the result as a PNG or SVG file — no software installation required.

Which barcode format should I use?

It depends on your use case. Use EAN-13 or UPC-A for retail products, Code 128 for shipping and logistics, Code 39 for asset tracking, and ITF-14 for outer cartons and bulk packaging.

Can I generate barcodes for free?

Yes — all barcode generators on this site are completely free with no usage limits. You can generate single barcodes, bulk batches, or sequential ranges without any cost, registration, or software installation.

What file formats can I download?

Generated barcodes can be downloaded as PNG for standard printing and digital use. For bulk or sequential batches, all barcodes are packaged together in a ZIP file for easy download.

Can I generate multiple barcodes at once?

Yes. The bulk mode lets you paste multiple values (one per line) and generates all barcodes simultaneously. For large batches you can also use the dedicated Bulk Barcode Generator which supports up to 500 barcodes at once and downloads them all as a ZIP file.

Can I generate sequential barcodes?

Yes. The sequential mode auto-generates a numbered series of barcodes using a configurable start value, end value, prefix, suffix, and increment — useful for inventory systems, asset tags, and product ranges.

What is the difference between EAN-13 and UPC-A?

EAN-13 is a 13-digit global retail standard used worldwide. UPC-A is a 12-digit format used primarily in the United States and Canada. An EAN-13 barcode starting with a leading zero is functionally equivalent to a UPC-A barcode.

Do generated barcodes include a check digit?

Yes. For formats that require a check digit — EAN-13, UPC-A, and ITF-14 — the tool calculates and appends it automatically from your input. You can also verify or calculate check digits manually using the Barcode Check Digit Calculator.
