FAQ
Which barcode formats are supported?
Nine mainstream 1D formats: CODE128 (general purpose, letters and digits), EAN-13, EAN-8, UPC-A, CODE39, ITF-14, Pharmacode, Codabar and MSI.
Why do I see a generation error after typing my content?
Several formats are strict about their input. EAN-13 needs 12-13 digits and UPC-A needs a fixed length, so content that breaks those rules raises an error. Check the number of characters and the character types.
What file format does the download button produce?
"Download SVG" exports the current barcode as an SVG vector file, ready for printing or further editing and scalable without any loss of quality.
Can I hide the text under the barcode?
Yes. Set the "show text" option to no and only the bar pattern is drawn, without the readable digits or characters.
