About this tool
Upload a barcode image from your phone or computer to see its format and decoded value without uploading the file or registering.
Read common 1D barcodes
The reader prioritizes EAN-13, EAN-8, UPC-A, Code 128, and Code 39. When BarcodeDetector is available, multiple barcodes in one image are listed separately.
Resize large images before decoding
Oversized images are resized in your browser before native detection or the ZXing fallback runs, avoiding repeated work on a full 20MP photo.
How to use this tool
- Upload an image containing a barcode.
- Click Read barcode and let the browser decode it locally.
- Review the format and value, copy a result, or scan another image.
Private, local processing
Your image and decoded value stay in this browser on this device. They are not uploaded to NexaForge or sent to analytics.
