Bulk Barcode Generator — Batch From a List
This bulk barcode generator turns a plain list into a whole batch of barcodes at once — paste your values one per line, click generate, and download the entire set as a ZIP of PNGs or open a printable label sheet. It is built for the moment you have 40 SKUs, 200 asset tags, or a warehouse bin list to encode and do not want to make each barcode by hand. Everything runs in your browser: no sign-up, nothing uploaded, capped at 250 values per run.
Create common barcodes.
How to use the bulk
- Switch the Barcode Generator to bulk mode and choose one symbology for the whole batch — CODE128 for mixed SKUs and asset tags, or EAN-13 / UPC-A if your list is retail product numbers.
- Paste your list into the box, one value per line; to add labels, write each line as value,caption (for example 100045,Medium T-Shirt) so the caption prints under that barcode.
- Click generate — the tool renders every line and validates each value, flagging any line it cannot encode so you can fix typos before printing. Keep each run to 250 values or fewer.
- Download the batch as a ZIP of individual PNG files to drop into a spreadsheet or label software, or open the printable label sheet to send straight to a printer.
- For a cut-ready page, use the label sheet and choose print to PDF; for a larger catalog, split it into multiple runs of 250 and repeat.
About the bulk
The whole point of batch mode is the input box. Instead of typing one value and downloading one image, you paste a list — one barcode per line — and the tool renders every line as its own barcode in a single pass. Each line can be just the value (SKU00123) or, if you add a comma, a value and a caption (SKU00123,Blue Widget 500ml). The part before the comma is what gets encoded into the bars; the part after the comma is the human-readable label the tool prints under that specific barcode, so your printout says "Blue Widget 500ml" instead of only the raw number. That one feature is what makes a batch actually usable on a shelf or a bin — a wall of identical-looking codes is far more useful when each carries its own plain-English caption. This is the same engine as the single-barcode tool and the Code 128 page; bulk mode just points it at a list.
Because the batch shares one symbology, pick the format that matches every value in your list before you generate. CODE128 is the safe default for internal use — it encodes any text or number, so mixed SKUs, location codes, and asset tags all pass. If your list is retail product numbers, choose EAN-13 or UPC-A and every line must be a valid digit string of the right length, because the tool validates each value against the chosen symbology and flags any line it cannot encode rather than silently producing a broken barcode. That per-line validation is the safeguard for a batch: one typo in a 200-line paste gets caught and named instead of shipping to a label printer. The run is capped at 250 values at a time, which keeps the browser responsive and is a sensible print-sheet size; for a larger catalog, split it into a couple of batches. If you only need one barcode as sharp vector art, the SVG page is the better tool — bulk mode outputs raster PNGs.
Once the batch is generated you have two ways out, and they suit different jobs. Download a ZIP and you get every barcode as a separate PNG file, named so you can drop them into a spreadsheet, a template, or your own label software. Open the label sheet instead and the tool lays the whole batch out on a printable page — captions included — that you send straight to a printer or "print to PDF" for a ready-to-cut sheet of tags. Both happen entirely on your device; your list of SKUs never leaves the browser. Two honest limits worth stating up front: this tool encodes numbers you already own, it does not assign or register GS1 company prefixes — if you need genuine retail EAN/UPC numbers, you buy those from GS1 first and paste them here. And it makes linear barcodes only, not QR codes; those live in the separate QR tool. For the barcode types and check-digit details behind a single code, see the Code 128 and EAN-13 pages, which are part of the same Barcode Generator.
Frequently asked questions
- What is a bulk barcode generator?
- It is a tool that creates many barcodes at once from a list instead of one at a time. You paste your values one per line, choose a symbology, and it renders the whole batch — then you download every barcode as a ZIP of PNG files or open a printable label sheet. This one runs entirely in your browser, needs no sign-up, and handles up to 250 values per run.
- How do I generate barcodes from a list or CSV?
- Switch to bulk mode and paste one value per line into the box. For a two-column list like a simple CSV, use the value,caption format — put the number or text to encode before the comma and the label to print under it after the comma, for example 100045,Medium T-Shirt. Copy the relevant column out of your spreadsheet, paste it in, and generate the whole batch in one click.
- How many barcodes can I make at once?
- Up to 250 values per batch. That cap keeps your browser responsive while rendering and happens to be a practical size for a single label sheet. If your catalog is larger, split it into multiple runs of 250 — each run downloads as its own ZIP or prints as its own sheet, so a 600-item list becomes three quick batches.
- Can I add a label or caption under each barcode?
- Yes — that is what the comma is for. Any line written as value,caption encodes the part before the comma into the bars and prints the part after it as the human-readable label beneath that specific barcode. So 100045,Medium T-Shirt shows "Medium T-Shirt" on the tag while encoding 100045. Lines with no comma just show the encoded value itself.
- Do I download a ZIP or a printable sheet?
- Either — you choose after generating. Download ZIP gives you every barcode as a separate PNG file, ready to drop into a spreadsheet, a design template, or label software. Open the label sheet lays the whole batch out on one printable page with captions, which you send to a printer or save as a PDF (print to PDF) for a sheet you can cut. Both are produced on your device.
- Which barcode type should I use for a bulk batch?
- CODE128 is the safe default for internal inventory, asset tags, and mixed SKUs because it encodes any text or number. Use EAN-13 or UPC-A only if your list is real retail product numbers — every line then has to be a valid digit string of the right length. The whole batch shares one symbology, so pick the format that fits every value before you generate.
- What happens if one value in my list is invalid?
- The tool validates every line against the symbology you chose and flags any value it cannot encode, rather than producing a broken barcode. So if you pick EAN-13 and one line has 11 digits instead of 12–13, or a letter sneaks into a numeric format, that line is called out. It is a real safeguard for a long paste — one typo gets caught instead of printed onto a label.
- Does this register GS1 barcodes or make QR codes in bulk?
- No to both. This tool encodes numbers you already own — it does not assign or register GS1 company prefixes, so genuine retail EAN/UPC numbers must be bought from GS1 first, then pasted here to make the images. It also makes linear barcodes only, not QR codes; those have a separate QR tool. Bulk mode is about turning a list of values you have into printable barcode images fast.
