QR Code & Barcode Repair

Upload a photo of a code that won't scan. The tool decodes what survives in the print and rebuilds a clean replacement to reprint.

Open repair tool

Paste one value per line, upload a CSV exported from Excel or Sheets (value,label per row), or set a prefix and starting number to auto-generate a sequence — the preview grid updates live and flags any code that fails its checksum before you print it. Pick the export that fits: Download all as a ZIP of individual PNGs, print an Avery-sized label sheet as a PDF, or send the grid straight to your printer.

A common use is asset tag barcodes — generate a Code 128 or QR code, print it, stick it on the equipment, and scan the barcode asset tag to pull up that item's record. See how asset tagging works in UNIO24, or follow the complete workflow for QR code asset tracking from first label to first scan.

Nothing you paste or upload ever leaves your device — codes render on-canvas locally, and the export libraries only load when you click a download button. Labeling a retail product instead of a batch of internal tags? The dedicated UPC barcode generator validates UPC-A, UPC-E, and EAN check digits one code at a time. Need a single customizable code instead of a batch? Try the QR code generator for links, Wi-Fi, or contact details with logo and color options. The barcode generator is built with barcodegen.online.

Bulk barcode generator — common questions

Quick answers about generating, exporting, and printing barcodes in batch.

  • Can I generate barcodes for free?

    Yes — completely free, no sign-up, no watermark, and no cap beyond the per-batch row limit shown in the tool. Generate as many batches as you need.

    Which barcode types can I create?

    CODE128 for general-purpose alphanumeric codes, EAN-13, EAN-8 and UPC-A for retail products, ITF-14 for shipping cartons, CODE39, Codabar and MSI for older warehouse and industrial systems, plus QR. Pick one from the symbology buttons at the top of the tool — the note under them spells out what that format accepts — and every row renders in it. Running a whole batch in CODE128, which is what most asset tags use? The bulk Code 128 barcode generator opens with that format already picked and covers its subsets, check character, and printing quirks.

    Can it make QR codes or other 2D barcodes?

    Yes, QR is one of the symbology options — or open the dedicated bulk QR code generator, which starts in QR mode with the same list, CSV, and sequence workflow. For a single QR code with logo and color customization, use the QR code generator instead.

    How do I turn an Excel list into barcodes?

    Export your Excel or Sheets column as CSV, then upload it or paste the CSV text directly — each row becomes one barcode, with an optional second column for a human-readable label under the code.
