About This Tool
The Barcode Generator creates standards-based Code 128 and EAN-13 barcodes directly in SVG. Code 128 works well for printable ASCII labels, while EAN-13 supports common retail-style numeric codes and automatically calculates a missing check digit.
ToolPool runs this utility in your browser, so your input stays on your device and is not uploaded to our server.

Workflow Tips
Barcode Generator is designed for quick browser work, but it is still worth reviewing the result before you use it in a live project, client document, public page, or production workflow. Keep an original copy of important source material, compare the output with what you expected, and repeat the task with slightly different settings when quality, formatting, or accuracy matters.
For larger workflows, pair this page with Barcode Reader, QR Code Generator, QR Code Decoder, Random Data Generator. Moving between related utilities can save time when you need to clean source data, prepare web assets, create supporting IDs, check calculations, or package output for another system. Internal links also make it easier to stay in one private workspace instead of jumping between several single-purpose sites.
The local processing model helps protect sensitive content because ToolPool does not need to receive your files, text, or form values to complete the task. Good privacy habits still matter after the result leaves the page: avoid pasting unnecessary secrets, check downloaded files before sharing them, and clear the workspace when you are finished on a shared computer.
