No. Barcode Generator processes your settings inside your browser, so it never reaches a DocTools server. That also means the tool keeps working if your connection drops mid-task.

No installation is needed. Barcode Generator runs in Chrome, Edge, Firefox and Safari, on desktop and on mobile, with no extension or plugin.
Can I use Barcode Generator on a phone or tablet?
Yes. The Barcode Generator interface adapts to small screens and supports touch input, though very large jobs are faster on a desktop browser.
