Free Barcode Generator Online — PNG & SVG, No Account Needed
You need a barcode. Maybe it's for a product listing, a warehouse shelf tag, a shipping label, or a quick prototype before packaging goes to print.
You don't need software for that. ToolHub's free barcode generator runs entirely inside your browser — nothing is uploaded, nothing is stored, no account required.
What ToolHub's Barcode Generator Actually Does
It creates real, scannable barcodes across eight industry-standard symbologies. You pick the format, type your value, tune the look, and download PNG or SVG. The whole thing takes under a minute from a cold start.
Everything generates locally using the JsBarcode library. There's no server round-trip, which means generation is instant and your data stays where it belongs.
The Eight Supported Barcode Formats
Different industries standardized on different barcode types decades ago. Using the wrong one means scanners won't read it. ToolHub covers the formats that actually matter:
| Symbology | Where It's Used |
|---|---|
| Code 128 | General-purpose; supports full ASCII — the safest default for most use cases |
| Code 39 | Broad scanner compatibility; uppercase letters, digits, and a handful of symbols |
| EAN-13 | Retail products and GTIN-13 — the standard barcode on most packaged goods worldwide |
| EAN-8 | Short retail codes for small packages where EAN-13 won't physically fit |
| UPC-A | North American retail; required by most US and Canadian retailers |
| ITF-14 | Outer shipping cartons and logistics case labels |
| MSI | Warehouse shelving, bin labels, and internal inventory systems |
| Codabar | Libraries, blood banks, courier systems — older but still very active |
Selling on Amazon or in grocery retail? Go EAN-13 or UPC-A. Tagging internal SKUs and warehouse bins? Code 128 or MSI. Shipping cases to a distribution center? ITF-14 is what the dock scanner expects.
Generating a Barcode — Step by Step
Open the tool and you'll find the configuration panel on the left, a live preview on the right. Changes reflect immediately.
- Select a symbology — the dropdown labels each format with a short hint so you don't have to guess
- Enter your barcode value — the tool validates input against each symbology's character rules in real time and tells you exactly what's wrong if anything fails
- Set bar dimensions — width (module thickness, 1–6) and height (30–200px) slide independently
- Pick your colors — foreground bar color and background color both use standard color pickers; black on white is the most scanner-reliable combination, but the tool won't stop you
- Configure the text label — toggle human-readable text on or off, set alignment to left, center, or right, dial in font size and text margin; you can also override the displayed text with a custom label entirely
- Choose output format — PNG for universal compatibility, SVG for resolution-independent professional output
- Download or share — grab the file, or copy a shareable link that encodes your entire configuration
PNG vs. SVG — Which Format Should You Export?
Short answer: SVG for professional print, PNG for everything else.
SVG is a vector format. It scales to any size without pixelating, which matters the moment you start working with label printers, design files, or packaging artwork. Figma, Illustrator, Inkscape, and most label-layout software all handle SVG natively. Hand an SVG off to a designer and they can resize it freely without loss.
PNG is universally compatible. Every browser, image editor, spreadsheet, and e-commerce listing form understands it. For quick use cases — pasting into a document, uploading to a marketplace, printing on a standard label sheet — PNG is zero-friction.
ToolHub generates both from the same configuration. Export whichever fits your workflow, or download both.
Shareable Barcode Configurations
This feature tends to surprise people. After setting up your barcode, hitting the share button encodes the full configuration — symbology, value, dimensions, colors, label settings — into a URL parameter.
Send that URL to a colleague, paste it into a Slack thread, bookmark it for a recurring label format. Opening the link loads the exact same configuration with no rebuilding. Teams managing consistent barcode styles across product lines find this genuinely useful.
Who Actually Uses This Tool?
E-commerce sellers — Generate EAN-13 or UPC-A barcodes for product listings. If you've registered GS1-compliant GTINs, you already have the numbers; ToolHub handles the visual output.
Inventory and warehouse teams — Code 128 and MSI both suit internal SKU and bin labeling well. Print on Avery stock or any standard label sheet and stick directly onto shelving or assets.
Logistics and shipping — ITF-14 for outer shipping cases; Code 128 for parcel labels and packing slips. SVG output drops cleanly into label templates.
Libraries and archives — Codabar remains active in library management systems and older database integrations. If your scanner reads Codabar, the tool will generate a valid one.
Designers and product teams — Mockups and packaging prototypes need real, scannable barcodes — not placeholder images. ToolHub generates correctly-structured barcodes that won't confuse QA teams or confuse test scanners on a production line.
Why Not Just Use Desktop Barcode Software?
Desktop barcode tools typically cost money, require installation, or both. The licensed ones can run several hundred dollars for a perpetual seat. The free ones are often years out of date, limited to one or two symbologies, or have exports gated behind a registration wall.
ToolHub is free, runs immediately on any device with a browser, and imposes no limits on how many barcodes you generate. For teams that need barcodes occasionally, that's an obvious trade. For developers integrating barcode generation into a workflow, the shareable-link mechanism handles configuration versioning without any infrastructure.
If you also need QR codes — for URLs, Wi-Fi credentials, vCards, or email actions — ToolHub's QR code generator covers those with the same privacy model. Both tools are available on the same generators page.
Common Questions
Does it work offline? Once the page loads, generation requires no network connection. Everything runs in the browser tab. Disconnect your internet after loading and it still works.
Is there a generation limit? No. Generate as many barcodes as you need. There are no daily quotas, rate limits, or paywalled export tiers.
Will the barcodes actually scan? Yes. The tool uses JsBarcode, which produces ISO/IEC-compliant outputs. Input is validated against each symbology's specific character constraints — if the value wouldn't produce a valid barcode, the tool tells you before generating.
What size should I export for print? Export SVG and scale to your label's exact dimensions in your design tool or label software — that removes the resolution question entirely. If you need PNG, setting bar height to 120–150px at default width produces a clean print at standard label sizes.
