Barcode Generator not working? Here's how to fix it
Most issues are small and fixable in seconds. Work through these in order.
1. The tool won't load
Reload the page, or open it in a fresh tab. If an extension blocks scripts, use private (incognito) mode — the tool needs JavaScript, which is on by default in every modern browser.
2. The value is rejected
Check that your input fits the selected format. EAN and UPC expect a specific digit length, while Code128 and Code39 accept more text.
3. I chose the wrong format
Pick the format that matches your use. Retail scanners expect EAN/UPC; for general text use Code128 or Code39.
4. The barcode won't scan
Make sure the value is correct and complete. Print at a reasonable size with enough quiet space around the bars, and prefer SVG for sharp edges.
5. Nothing downloads
Check your browser's download location and pop-up/file settings. Many browsers quietly block automatic downloads from new sites.
Still stuck?
Try a different current browser (Chrome, Firefox, Safari, Edge). Because the tool runs locally, a fresh environment usually resolves remaining edge cases.
Verdict
Most Barcode problems are solved by a valid value, the right format, or a reload.
