Which format should I use?

CODE128 accepts any text and is the most flexible; EAN-13 and UPC are the standard retail-product formats (fixed-length numeric); CODE39 is common in logistics/inventory.

Why did my value get rejected for a format?

Each format has its own valid input rules (e.g. EAN-13 needs exactly 12-13 digits) - a value that does not match will show a clear error instead of a broken barcode.

Does this tool upload what I type?

No - the barcode is rendered on a canvas in your browser; nothing is sent to a server.
