About Bulk QR Generation
Paste a list of values one per line — all values must be valid for the selected format. For example, EAN-13 requires 12 digits per line, Code 128 accepts any text. Invalid entries are skipped and flagged. Download the full set as a ZIP of PNGs, or click any individual barcode to save it separately.
Frequently Asked Questions
How many barcodes can I generate at once?
Up to 100 barcodes per batch. Each value on a new line gets its own barcode image using the same format and settings. For larger volumes, generate in multiple batches and combine the downloads.
What happens if my input is invalid for the chosen format?
Invalid entries are skipped and flagged with an error message. For example, entering letters into an EAN-13 field will error — EAN-13 accepts digits only. Valid entries in the same batch still generate successfully.
Which format should I use for bulk retail barcodes?
For retail products with GTIN numbers, use EAN-13 or UPC-A. For internal tracking, shipping, or custom codes, Code 128 is the most flexible — it accepts any text or numbers and is universally scannable.
How do I check a new batch of barcode numbers against ones I already use?
Paste the new numbers as List A and your existing inventory numbers as List B in ListDiff's Compare Two Lists. Anything shown as appearing in both lists is already in use; the rest are safe to assign. It runs entirely in your browser.
