BARCODE GUIDE
What is a barcode generator, and when should you use one?
Barcodes are still the backbone of retail, inventory and logistics. They’re fast for scanners, reliable for systems, and universally supported by POS setups. Kompi’s online barcode generator keeps the workflow clean: pick a format, encode your value, then export a crisp asset you can print anywhere.
CHOOSING FORMATS
Picking the right barcode type
Different barcode standards exist for different environments. Here’s a simple mental model:
- Code 128: flexible and high-density — great for logistics, internal labels and alphanumeric IDs.
- EAN-13 / EAN-8: common retail barcodes across many regions — often required for packaged goods.
- UPC-A / UPC-E: widely used in North America for consumer products.
- Code 39: simple and robust — good for assets, documents, badges and internal tracking.
If your retailer, marketplace, or scanner vendor specifies a format — follow that spec. Otherwise, Code 128 is a strong default for internal workflows.
BEST PRACTICES
Print, size and scan reliability
A good barcode is mostly about clarity: sharp edges, enough quiet space (blank margin), and printing at a sensible size for the scan distance. Always print a sample and test it with your actual scanner before rolling out at scale.
Labels & bins
For shelves and bins, prioritize readability over compactness. A slightly larger barcode prevents mis-scans.
Packaging
Avoid curved or glossy areas when possible. Test under real lighting and handling.
Documents
PNG works well for docs and quick prints; use SVG if your designer will scale it significantly.
For customer-facing experiences, pair barcodes with QR codes so machines and people both have a clean path.
BARCODES FOR EVERYDAY OPERATIONS
One barcode generator, three very normal use cases.
Retail, warehousing, internal labels — generate barcodes that scan reliably and download assets that print clean.
RETAIL & ECOMMERCE
Product & shelf labels
Turn SKUs, GTINs and product IDs into scan-ready barcodes for checkout and stock counts.
- • EAN / UPC formats for retail
- • Print clean labels fast
- • Pair with QR for customers
Warehousing & logistics
Use Code 128 for locations, totes, pallets and manifests in fast-moving environments.
- • Label aisle / rack / bin
- • Speed up picking
- • Reduce manual entry
INTERNAL & EVENTS
Assets, passes & docs
Add scannable IDs to devices, badges and files so everything stays trackable.
- • Track gear and equipment
- • Add IDs to paperwork
- • Combine with QR for info
Your barcodes shouldn't live in a totally separate system.
Generate barcodes that sit alongside QR codes, links, menus and analytics. One workspace, one workflow — not five random tools.

COMPARISON
Kompi vs typical barcode tools
Traditional barcode tools are often clunky, desktop-first, and disconnected. Kompi is clean, web-based, and part of a bigger workflow.
| Feature | Kompi Barcode Generator | Typical tools |
|---|---|---|
| Access | Runs in your browser, no installs. | Often desktop apps or dated sites. |
| Formats | Common retail + ops formats (EAN/UPC/128). | Limited formats or confusing controls. |
| Export quality | Crisp PNG + scalable SVG. | Often PNG-only or low-res. |
| Connected workflow | Integrates with QR codes, links and workspaces. | Barcode-only, disconnected tools. |
| Team friendly | Built for creators, brands and agencies. | Single-use downloads. |

FAQ
Barcode generator FAQs
Everything you need to know about using Kompi as your online barcode generator.
What is a barcode generator and how does it work?+
A barcode generator is an online tool that converts product codes, SKUs, GTINs or internal references into a scannable barcode image. Kompi’s barcode generator lets you choose the barcode type, enter your data, preview the result and download high-quality PNG or SVG barcodes for labels, packaging and documents.
Is the Kompi barcode generator free to use?+
Yes. You can use Kompi’s barcode generator online for free to create and download barcodes for everyday use. When you’re ready for more, you can upgrade to a Kompi workspace for features like QR codes, analytics, dynamic links and team collaboration.
Which barcode formats can I create with Kompi?+
Kompi supports popular 1D barcode types used in retail, ecommerce and logistics, including Code 128, EAN-13, EAN-8, UPC-A, UPC-E and Code 39. Pick the format that matches your POS system, warehouse scanners or marketplace requirements before generating your barcode.
Can I download barcodes as high-quality PNG or SVG?+
Yes. After you generate a barcode with Kompi, you can download it as a high-resolution PNG image or as a vector-based SVG. PNG is ideal for quick print and digital use, while SVG is perfect for professional printing where you might resize the barcode without losing sharpness.
Do I need to install any software?+
No. Kompi’s barcode generator runs fully in your browser. You don’t need any desktop software or driver configuration — just open the page, enter your data and download your barcode from any modern device.
Can I use Kompi barcodes in a physical retail store?+
Absolutely. Many merchants use Kompi to generate barcodes that are compatible with their scanners and POS systems. Just be sure you’re using valid product identifiers such as GTIN or EAN codes when required by your retail partners or marketplaces.
What’s the difference between barcodes and QR codes?+
Barcodes are 1D codes made of vertical lines that encode a limited amount of numeric or alphanumeric data, ideal for products, inventory and logistics. QR codes are 2D codes that can store more data, such as URLs, menus and contact cards. Kompi supports both barcodes and QR codes so you can handle product identification and customer experiences in one platform.
Can I track scans from my barcodes?+
Standard 1D barcodes don’t include analytics by themselves, but Kompi helps you connect barcodes to smart destinations. For example, combine barcodes with Kompi Links and QR codes that route through trackable URLs, so you can understand engagement alongside your other QR and link campaigns.
Is there a limit to how many barcodes I can generate?+
For normal usage there’s effectively no practical limit — you can generate as many barcodes as you need for SKUs, shelves, bins and internal labels. If you’re automating barcode generation at scale, using Kompi workspaces and a paid plan is recommended for reliability and collaboration.
TRUST
Reliability, privacy and responsible barcode use
Barcodes are only as good as the data and printing behind them. Keep identifiers clean, prints sharp, and scans tested.
Use consistent identifiers (GTIN/EAN where required, or clean internal conventions for locations and assets). Print at sensible sizes and test with your actual scanner hardware before rolling out at scale.
For customer-facing journeys, pair barcodes with QR codes that route through destinations you control. Use Kompi workspaces to keep everything organised across teams, brands and campaigns.
If you’re combining barcodes with trackable links, keep destinations branded and trustworthy — the experience depends on where people end up.
