Bulk barcode generator: one list in, a sheet of labels out
Making barcodes one at a time is fine for a single product and hopeless for a catalogue. Paste your SKUs or item codes — one per line, or a CSV with a label column — pick a format, and every line becomes its own scannable barcode. The preview shows what will print, invalid rows are flagged before you download anything, and the batch arrives as individual PNG files or one printable A4 PDF sheet with the labels lined up for cutting. Everything is generated in your browser, so a list of supplier or customer codes never leaves your machine.
Frequently asked questions
What is a bulk barcode generator?
A bulk barcode generator turns a whole list of codes into many barcodes in one batch. You paste your SKUs or item codes, one per line, or upload a CSV, choose a format such as Code 128 or Code 39, and the tool renders a scannable barcode for every line — then hands you a printable A4 label sheet or individual PNG files. It replaces generating each barcode one at a time, which stops being practical beyond a handful of items.
Which barcode format should I use in India — Code 128 or Code 39?
Code 128 is the better default for most Indian businesses: it encodes any text in less space, is accepted by every logistics and inventory system, and suits shop labels, invoices, asset tags and warehouse bins. Code 39 is an older standard still demanded by some legacy and government formats; it supports only uppercase letters, digits and a few symbols, and produces wider barcodes. If a buyer or a marketplace has not specified a format, generate Code 128.
Can I generate EAN-13 barcodes in bulk?
Yes. Choose EAN-13 and paste 12-digit numbers, one per line; the 13th check digit is calculated automatically, and a wrong check digit is flagged before you download anything. One caution: EAN-13 numbers printed as retail product identifiers in India are allocated by GS1 India, so use your own GS1-issued numbers on packaging and marketplace listings. Generated codes are perfect for internal stock, MRP labels and warehouse use.
How many barcodes can I generate at once?
Up to 1,000 barcodes in a single batch, which is why people reach for a batch barcode generator rather than a single one. Paste one code per line, and an optional second column after a comma sets the text printed under each barcode. Rows that do not match the chosen format are listed in red with the reason and are excluded from the download, so one typo cannot spoil a whole sheet.
How do I download many barcodes at once?
Use “Download all as PDF”. Every barcode is laid out on A4 sheets at your chosen label size, with the value printed under each one so it can be checked by eye, and the sheet is ready to print and cut. You can also save any single barcode as a PNG from the preview grid. Nothing is uploaded — the PDF and the images are created inside your browser.
Are these barcodes free to use commercially?
Yes. The generator is free, with no sign-up, no watermark and no restriction on commercial use of the files you create. The one thing to keep separate is the numbering: EAN-13 codes used on retail products must come from GS1, while self-generated Code 128 or Code 39 codes are fine for your own stock, invoices, dispatch and internal tracking.
