When you cannot scan a QR code directly or need to extract information from a screenshot, this tool provides a convenient solution. A QR code decoder is an online tool that uses image recognition algorithms to automatically read the raw data encoded in a QR code matrix. As a common two-dimensional barcode, a QR code essentially encodes information (such as text, URLs, contact details, etc.) into a matrix of black and white squares. The task of this tool is to reverse-decode this process and output the original string information contained in the QR code.
1. What should I do if the decoded QR code shows garbled text?
This usually means the QR code itself encodes binary data or uses a non-standard character set. This tool outputs the raw byte data stored in the QR code; if the encoded content is not plain text, it will appear as garbled characters. For example, a QR code encoding a file or specific application data will result in an unreadable byte sequence.
2. What is the maximum supported image size?
The maximum file size for a single image is 2MB. This limit ensures fast decoding speeds and server stability, as oversized files may cause upload or processing failures.
Please ensure the uploaded QR code image is clear, complete, and free of glare or obstructions. The image file size must not exceed 2MB. This tool only provides data extraction services and assumes no responsibility for the decoded content (such as link safety or information authenticity); users must exercise their own judgment. Only one image can be processed at a time.
To improve the decoding success rate, we recommend uploading QR code images with high contrast (e.g., a dark QR code on a light background). For photos taken of screens or printed documents, there may be distortion or moiré patterns; try using image editing software to crop and straighten the image before uploading. This tool is designed for standard QR Code symbology decoding. A typical example: inputting a QR code image containing the URL "https://example.com" will output that exact URL string.
