Frequently Asked Questions

What types of QR codes can it read?

Vizua asks the browser’s BarcodeDetector for qr_code results and displays each returned rawValue as text, with URL-like values made clickable. Detection and payload interpretation are browser-dependent; damaged, low-contrast, tiny, stylized, unsupported, or malicious codes may fail or require caution.

Which browsers are supported?

The tool requires a browser that exposes BarcodeDetector and accepts the qr_code format. Support can vary by browser version, operating system, runtime flag, and device, so Vizua checks the API at runtime instead of promising a fixed browser list.

Can it read multiple QR codes?

It displays every QR result returned by one detector call, but no image or browser is guaranteed to return all visible codes. Verify critical payloads independently and inspect a URL before opening it.

Tips for better results

  • Start with the cleanest source available; a small, blurry, or heavily compressed file contains less detail to preserve.
  • Check dimensions and format before downloading so the result matches the site, app, printer, or platform where you will use it.
  • For large files, close unnecessary tabs and test one representative file before processing a full batch.
  • Open the downloaded result once before sharing it or replacing an original.

Where QR Code Reader — Decode from Image fits in a workflow

Use QR Code Reader — Decode from Image for one-off adjustments or as a preparation step before publishing, sharing, archiving, or continuing the edit in another application. When batch processing is available, validate the settings on a small sample first and then apply them to the remaining files.
