Image Metadata Viewer は何をしますか？
Image Metadata Viewer はブラウザ上でデータを調査するツールで、結果と制限を明確に示します。 検証済みの機能： EXIF inspection, GPS field visibility, XMP and IPTC parsing, No metadata upload.
Metadata can be useful and privacy-sensitive
Keep camera and rights fields when they support an asset workflow. Remove or review GPS, device identifiers, author names, and timestamps before publishing a photo when they could expose private information.
使い方
- Choose one supported local image no larger than 50 MB.
- Select Read metadata to parse available EXIF, TIFF, XMP, IPTC, ICC, GPS, and container fields.
- Search the JSON result for location, camera, date, author, or rights fields before sharing the image.
実際の入出力例
Inspect a JPEG carrying camera information
入力
photo.jpg with EXIF Make="Canon" and Model="EOS R"出力
{"file":{"name":"photo.jpg","type":"image/jpeg"},"metadata":{"Make":"Canon","Model":"EOS R"}}Only fields physically present in the selected file appear; the tool does not infer missing camera or location data.
一般的なエラーと対処
| 症状 | 原因 | 対処 |
|---|---|---|
| The result contains file facts but no EXIF fields. | The image was exported without metadata or a service stripped it. | Inspect the original camera file; metadata cannot be recovered from pixels after removal. |
| A date or GPS value looks unexpected. | Metadata may omit a time zone, use camera-local time, or store coordinates separately from display formatting. | Cross-check the original device settings and treat metadata as recorded claims, not guaranteed truth. |
Important behavior of Image Metadata

Image Metadata — FAQ
Does the Image Metadata upload my input?
No. Processing runs in the current browser tab, and the page does not send tool input to a KitLumi processing endpoint.
What input does the Image Metadata accept?
It accepts one supported local image file. The workspace checks the input and reports malformed or unsupported values before it produces a result.
What does the Image Metadata produce?
It produces formatted JSON containing file facts and available metadata fields. Copy and download controls appear when the output format supports them.
What limitation should I know?
GPS fields can reveal sensitive location information; review metadata before sharing a photo.
