Best Free Barcode Generators Online 2026 — Compared
Table of Contents
There are dozens of free barcode generators online. Most people land on one via search, use it once, and never think about it again. But if you are generating barcodes regularly — for inventory, retail products, or shipping — the tool you pick actually matters: watermarks, upload requirements, format support, and output quality vary significantly.
Here is an honest comparison of the most-used free options, what they do well, and where they fall short.
The Main Free Barcode Generator Tools Compared
| Tool | Formats | SVG? | Upload? | Watermark? | Account? |
|---|---|---|---|---|---|
| WildandFree Tools | CODE128, EAN13, UPC, CODE39, ITF14, Pharma | Yes | No (browser) | No | No |
| Barcode.tec-it.com | 100+ formats | Yes | Server | Yes (free tier) | No (limited) |
| Online-Barcode-Generator.net | ~20 formats | No (PNG only) | Server | No | No |
| Labelary.com | ZPL only | No | Server | No | No |
| Barcodesinc.com | ~30 formats | No | Server | No | No |
| Free-Barcode-Generator.net | ~15 formats | No | Server | No | No |
Barcode.tec-it — Most Formats, But Free Tier Is Watermarked
TEC-IT is a professional barcode software company. Their online generator supports 100+ symbologies including exotic formats most tools do not offer (PDF417, Data Matrix, Aztec, GS1 DataBar). For specialized industrial or logistics formats, this is the most comprehensive free option.
Downside: The free online version adds "TEC-IT" branding to downloaded barcodes. Clean output requires a paid license or their desktop software. For the six common formats, there is no reason to accept a watermark when cleaner alternatives exist.
Sell Custom Apparel — We Handle Printing & Free ShippingOnline-Barcode-Generator.net — Simple, Server-Side, Clean Output
One of the older tools in this space. Clean PNG output with no watermark, supports around 20 formats, simple interface. The main limitations: no SVG export, one file at a time, server-side processing (your data is uploaded), and the UI has not been updated in years.
Good for a quick one-off CODE128 or EAN-13. Not ideal for batch work or when SVG is needed for label design.
Labelary — For ZPL Labels Only
Labelary is not a general barcode generator — it is a ZPL (Zebra Programming Language) label previewer. If you are working with a Zebra thermal printer and writing ZPL code, Labelary shows you what the label will look like before printing.
Not useful for generating a standalone barcode image. Mentioned here because it appears in searches for barcode generators and confuses people who end up on the wrong tool.
When a Desktop App Makes More Sense
For very high-volume or automated workflows, a free desktop tool may be more practical than any browser option:
- Zint Barcode Studio (free, open-source): Windows/Mac/Linux desktop app that generates any barcode format with no limitations. Good for batch jobs via command line.
- GNU Barcode: Command-line tool for Linux. Integrates into scripts and automated label printing pipelines.
For 1-100 barcodes at a time, a browser tool is faster and requires no installation. For thousands of barcodes in an automated pipeline, a CLI tool is more appropriate. See the full online vs desktop comparison.

Open Free Barcode GeneratorFrequently Asked Questions
Which free barcode generator is best for EAN-13?
For EAN-13 specifically: WildandFree Tools (browser, no upload, SVG+PNG, no watermark) or Online-Barcode-Generator.net (server-side, PNG only, no watermark). Both calculate the check digit automatically. WildandFree is better if you need SVG for label design.
Is there a free barcode generator that supports all formats?
For the six most common formats (CODE128, EAN-13, UPC-A, CODE39, ITF-14, Pharmacode), WildandFree Tools covers them all free with no watermark. For exotic or industrial formats (PDF417, Data Matrix, GS1 DataBar), TEC-IT has the widest format support, but adds a watermark on free downloads.
Can I trust free barcode generators with proprietary SKU data?
It depends on whether the tool is browser-based or server-side. Browser-based tools (like WildandFree) process data locally — your SKUs never leave your device. Server-side tools send your barcode data to their servers during processing. For sensitive data, use a browser-based tool.
