Generate barcodes in bulk from a list
Paste your values, upload a CSV, or make a numbered batch, and get a barcode for each. Download PNGs in a ZIP, or a print-ready PDF of label sheets.
Ten formats, each value checked as you type. Your list is processed in your browser.
What you get
- Four ways in
- Paste one value per line, load a CSV (with an optional caption column), make a numbered series, or make random codes that are all different.
- Ten formats, checked for you
- Code 128, Code 39, EAN-13, EAN-8, UPC-A, ITF-14, Interleaved 2 of 5, MSI, Codabar and Pharmacode. Every row shows whether it is valid, and if not, what that format accepts. Repeats are flagged.
- Your styling
- Bar width and height, empty border, text size and position, colours or a see-through background, and a different caption under any code.
- PNG ZIP, SVG ZIP or label sheets
- A ZIP of images up to 4x size, a ZIP of SVGs, or a print-ready PDF on A4, A3, A5, US Letter or US Legal.
- Label sheets that line up
- Pick a common label size or your own, set copies, and skip labels you have already used on a part-filled sheet. Barcodes are centred and never stretched.
- See the page first
- A picture of each page shows exactly where every label lands before you export.

How to generate barcodes in bulk from Excel or CSV
Typing barcodes one at a time does not scale past a handful. This tool turns a whole list into barcodes in one pass: paste it, upload it, or generate a numbered batch.
- Put your values in one column of a spreadsheet, one per row: SKUs, product numbers, asset tags or batch IDs.
- Save that as CSV. In Excel use File > Save As > CSV; in Google Sheets use File > Download > Comma-separated values.
- Load the CSV, or paste the values into the box, one per line. To make a series instead, press Make a series (a prefix, a first number, a count and a step) or Random codes.
- Pick a format. Every row shows whether it is valid for that format. Adjust bar width, height and colours in the style panel.
- Export a ZIP of PNG or SVG images, or generate a print-ready PDF of label sheets.
Which barcode format should you use?
| Format | Accepts | Typical use |
|---|---|---|
| CODE128 | Letters, digits and symbols (ASCII) | Inventory, shipping, internal IDs |
| CODE39 | Capital letters, digits, - . space $ / + % | Asset tags, older systems |
| EAN-13 | 12 digits (check digit added) or 13 with a valid check digit | Retail products |
| EAN-8 | 7 digits (check digit added) or 8 with a valid check digit | Small retail packs |
| UPC-A | 11 digits (check digit added) or 12 with a valid check digit | Retail products, North America |
| ITF-14 | 13 digits (check digit added) or 14 with a valid check digit | Cartons and cases |
| MSI | Digits | Shelf and warehouse labels |
If a barcode does not appear, the value probably does not fit the format. The most common cause is an EAN-13 or UPC value with the wrong number of digits or a wrong check digit. Fix the row, or switch to CODE128, which accepts almost any text.
Printing barcodes on label sheets
The PDF export lays barcodes out on a page for printing. Choose the paper (A4, A3, A5, US Letter or US Legal), portrait or landscape, a common label size or your own, how many labels go across and down, the gap between labels, and how many labels to skip if the sheet is part used. The page picture shows where every label lands before you export.
- Print at 100% or "actual size". Scaling to fit changes the bar widths and can make barcodes harder to scan.
- Leave the blank margin around the bars alone. Scanners need that quiet zone to find where a barcode starts and ends.
- Scan one printed sample with your real scanner before printing hundreds.
Free, private, and honest about the limits
There is no account, fee or watermark, and your list is processed in your browser rather than uploaded. The trade-off is that large batches run on your own device: a list can have up to 1000 codes, and if it slows down you can split it. For more on choosing a format, see barcode formats explained.
