— frequently asked questions

Which format should I use for retail products?

EAN-13 for most international retail products, UPC-A for North American retail.

Why does EAN-13 ask for 12 digits instead of 13?

The 13th digit is a check digit calculated automatically from the first 12 — the tool adds it for you.

Can I print the SVG output?

Yes — SVG is vector format and scales to any print resolution without pixelation.

Is there a limit on batch mode?

There is no hard limit, but very large batches may take a moment to package into a ZIP.

Is this free?

Yes — free with no sign-in.

— ready to use it?

Free. Instant. No sign-in. Open it and get the job done.
