Barcode Decoder

Quick Start

1
Upload an image: drag and drop or click to select. Supports PNG / JPEG / WebP / AVIF / HEIC / HEIF.
2
Start decoding: click "Decode barcodes" to parse barcodes in the current image.
3
Review results: check decoded text, barcode format, and position for each detected result.
4
Copy one: use the "Copy" button on each result item.
5
Copy all: use "Copy all" to copy every decoded result in one click.
6
Retry decoding: replace the image or clear and run again.

Common Scenarios

Packaging and label QA

verify barcode content on product labels, shipping stickers, or printed materials.

Single-image multi-code check

decode multiple barcodes in one image and verify item by item.

Code audit

verify encoded values such as batch IDs, serial numbers, and order references.

Archive extraction

extract barcode content from screenshots, camera photos, or scanned documents into copyable text.

Detection capabilities

Single-image flow: upload one image at a time; one or multiple barcodes can be decoded from it.
Stable ordering: multi-barcode results are sorted from top-left to bottom-right.
Position hint: each result includes top/left/width/height for easier cross-checking.
Format badge: shows the detected barcode type. Current support includes EAN-13, EAN-8, UPC-A, UPC-E, Code 128, Code 39, Data Matrix, PDF417, and Aztec.

Usage Advice

Use clear, well-focused images with minimal glare whenever possible.
Keep enough white margin (quiet zone) around the barcode and avoid tight crops.
For noisy backgrounds or partial occlusion, crop the barcode area first and retry.
HEIC/HEIF files are preprocessed in-browser before decoding, so they may take longer than JPEG/PNG.
After decoding, spot-check key characters such as batch IDs, serial numbers, order IDs, or product codes.

Limitations & Compatibility

This is an image-based workflow and does not include live camera scanning.
GIF input is not supported (including animated GIF). Convert to PNG/JPEG/WebP first.
BMP/TIFF/PDF input is currently not supported.
Only one image is processed at a time; multi-image batch upload is not supported.
Severe blur, heavy perspective distortion, or large occlusion may cause decode failures.

Privacy & Security

All processing happens locally in your browser. You can replace, clear, and decode again at any time.
If barcode content is sensitive, use this tool on a trusted device and network.
Before copying, exporting, or sharing decoded results, verify critical values to avoid mistakes or misuse.
