Free Bulk Barcode Generator

🔒 Runs in your browser — nothing is sent to a server

Generate barcodes in bulk online for free. Paste a list of values — one per line — pick a format (Code 128, EAN-13, EAN-8, UPC-A, Code 39, or ITF-14), and the generator produces a separate print-ready barcode for every row. Preview each code individually, copy or download any single barcode as PNG or SVG, or grab the whole batch as a single ZIP archive. Ideal for asset-tag runs, event-ticket sheets, warehouse bin labels, inventory rollouts, and any workflow where copying-and-pasting into a single-code generator would take hours. Everything runs inside your browser — no uploads, no account, no rate limits.

Common bulk-generation use cases

The bulk workflow exists because some jobs are intrinsically many-at-once: onboarding IT assets with sequential internal IDs, printing a block of numbered event tickets, issuing classroom library cards at the start of term, labelling the entire bin layout of a new warehouse, or generating gift-certificate codes for a promotion. In each case, the payloads are known up front and the style is uniform — exactly what batch mode is built for.

Tips for laying out a printable sheet

If the final output is a physical sheet of labels, decide label dimensions first, then tune the generator settings to match. Set bar width to the largest value that still fits your label (2–3 px for A4 office labels), enable a comfortable margin (15 px or more) for the quiet zone, and show the human-readable value beneath the code for visual matching. Export as SVG, then drop the files into your label-sheet template and let the template handle the grid placement.

FAQ

How do I generate multiple barcodes at once?

Switch to "Multiple codes" mode, then paste your list into the text area with one value per line. Every non-empty line becomes a separate barcode in the preview grid below. You can regenerate instantly after tweaking the style, then download any individual code or export the entire batch as a ZIP archive containing a PNG or SVG for every row.

How many barcodes can I generate in a single batch?

There is no hard cap imposed by the generator — every barcode is rendered directly in your browser, so the practical limit is whatever your device can handle without the tab becoming sluggish. In testing, modern laptops handle 500+ barcodes comfortably and will manage 1,000+ with a brief render pause. For very large batches (tens of thousands), split the work into chunks of 500–1,000 for the smoothest experience.

Can I mix different barcode types in one batch?

Not in a single run — the selected barcode type (Code 128, EAN-13, and so on) applies to every line in the list. If you need a mixed-type batch, run the generator separately for each type and then combine the resulting ZIPs. Within one type, however, every line is encoded independently, so you can freely mix short and long payloads as long as they all satisfy the type rules.

How do I download every barcode as a ZIP?

After generating the batch, scroll to the bottom of the preview grid. You will see two buttons: "Download all PNG as ZIP" packages every rendered code as a PNG file inside a single archive, and "Download all SVG as ZIP" does the same for SVG. Each file inside the archive is named after the encoded value, so matching a barcode to its payload later is trivial.

Can I customise each barcode individually in batch mode?

Style settings — bar width, height, margin, rotation, font, and text alignment — apply uniformly to every barcode in the batch. That is usually what you want for a printable sheet, where consistent dimensions are essential. If you need per-code variation (different sizes, colours, or fonts), generate the batch first and then process the SVG files externally, or run several batches with different settings.

Is there a smart way to print a sheet of bulk barcodes?

Yes. Export the batch as SVG, then import the files into a label-sheet layout in Word, Avery Design & Print, or any DTP application — vector graphics rescale without blurring, so the same files work across every label size. If you need a quick print of just a few codes, the preview grid includes a "Print" button that opens a browser print dialog with all barcodes arranged on the page.

Glossary

Batch processing

Running the same operation over many input records with a single command. In this generator, batch processing turns a pasted list of payloads into an equal-length series of barcodes rendered in one click — the alternative to repeating the single-code workflow once per item.

ZIP archive

A compressed container file holding many individual files as a single downloadable unit. The bulk generator packages every rendered PNG or SVG into a ZIP so you only have to manage one download, and file names inside the archive are derived from each barcode payload for easy lookup.

Asset tag

A durable barcode label attached to a physical asset (laptop, projector, tool, chair) that encodes a unique internal identifier for inventory tracking. Asset-tag runs are one of the most common use cases for bulk barcode generation — IT departments commonly issue labels in batches of hundreds when onboarding new hardware.

SKU (Stock Keeping Unit)

An internal alphanumeric product identifier used by retailers and warehouses to track inventory distinct from the GTIN used at retail checkout. Bulk generation of SKU barcodes (almost always as Code 128) is a frequent task when launching a new product line or migrating to a new warehouse management system.

Label sheet

A pre-perforated sheet of adhesive labels (Avery 5160, DYMO, Herma, etc.) arranged in a grid, designed to be fed through an office printer. Exporting bulk-generated barcodes as SVG and laying them out on a label sheet is the fastest way to produce hundreds of physical labels without specialist equipment.
