Linear barcode scanner

Client

Upload an image to read 1D barcodes—Code 128, EAN-13, UPC-A, and related retail formats. Generate new bars on the linear barcode generator.

Barcode scanner for Code 128 and retail EAN/UPC

Searches like “barcode scanner 128”, “128 barcode scanner”, and “code 128 barcode scanner” usually mean reading existing vertical bars from a photo—not generating new ones. Upload PNG or JPEG; BarcodeDetector in Chrome, Edge, or Opera returns the payload locally. Pair with the linear barcode generator to recreate or resize labels.

Read Code 128, EAN-13, EAN-8, UPC-A, and related linear barcodes from a photo or screenshot—create bars on linear barcode generator or matrix codes on QR decoder. Still-image upload only; no live camera.

PNG, JPEG, WebP, or GIF up to 8 MB.

?
Hold the label flat, fill the frame with bars, and avoid glare. Code 128 needs quiet zones (white margin) on both sides. Very small codes may need a higher-resolution source photo.

Nearby workflows on Toolcore

  • Linear barcode generator — to render Code 128, EAN-13, or UPC-A from copied digits.
  • GTIN check — to validate GS1 check digits on scanned retail numbers.
  • QR decoder — when the label is a square QR matrix, not linear bars.
  • QR generator — for Wi‑Fi or URL matrix codes after verifying linear SKUs.

Common use cases

  • Read a Code 128 or EAN-13 payload from a product photo without a handheld scanner.
  • Verify printed barcodes match the digits in your catalog before relabeling.
  • Copy GTIN digits into checksum tools after scanning a packaging screenshot.

Common mistakes to avoid

  • Expecting QR matrix codes

    This page reads linear (1D) bars only. Square QR codes belong on the QR decoder page.

  • Safari or Firefox without BarcodeDetector

    1D scan needs Chrome, Edge, or Opera on desktop today. Use the generator with typed digits elsewhere.

  • Blurry or skewed photos

    Re-shoot with the bars horizontal, higher contrast, and quiet white margins on both ends.

FAQ

Is the image uploaded to a server?

No—decoding uses the BarcodeDetector API in your browser on a canvas draw of your file.

Which barcode types are supported?

Code 128, Code 39, EAN-13, EAN-8, UPC-A, UPC-E, and ITF when your browser exposes them via BarcodeDetector.

Does this replace a hardware scanner?

It reads still images you upload—not a live camera stream. For warehouse line scans, use dedicated hardware; this helps desktop verification and screenshots.

Can I generate a barcode from the result?

Yes—use Copy payload, then Open in generator, or follow the GTIN check link for retail digits.
