Practical Use Cases
Privacy review
Check whether an image contains location or camera data before sharing.
Capture inspection
Review recorded date, equipment, and exposure fields when available.
Privacy and File Processing
Exif Viewer keeps its Images containing supported EXIF metadata input in browser memory while the operation runs. The workflow creates ZIP, JSON metadata report, or Metadata-free PNG when selected for local preview or download and does not send the entered values or selected file bytes to the GXA Toolbox application server.
Supported Inputs and Outputs
Input
- Images containing supported EXIF metadata
Output
- ZIP
- JSON metadata report
- Metadata-free PNG when selected
Quality and Fidelity
The optional clean copy is decoded and re-encoded as PNG. Visible pixels are retained through canvas rendering, but color profiles, animation, and source encoding details may change.
Limitations and Important Notes
- Not every metadata block or vendor-specific tag is parsed.
- Absence from the report is not a forensic guarantee that all hidden data is absent.
- The PNG clean copy may be larger than a source JPEG.
Worked Example
Use a representative source image, apply Exif Viewer, and compare the result with the original at full size before publishing it.
Helpful Tips
- Keep the untouched source image while evaluating Exif Viewer.
- Check the ZIP or JSON metadata report or Metadata-free PNG when selected result at its intended display size.
