使用结果前如何检查？
本工具查看所选文件中存在的元数据。未发现 GPS 字段不代表图片没有可识别内容；查看不会移除元数据，也不会修改原文件。
Image Metadata Viewer可以处理什么？
Image Metadata Viewer 用于在浏览器中检查数据，并清楚显示处理结果和限制。 已核对的功能： 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.
如何使用？
- 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.
实际输入输出示例
Inspect a JPEG carrying camera information
输入
photo.jpg with EXIF Make="Canon" and Model="EOS R"输出
{"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.
常见错误与修复方法
| 现象 | 可能原因 | 修复方法 |
|---|---|---|
| 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
该工具的实际边界： GPS fields can reveal sensitive location information; review metadata before sharing a photo.
标准与实现参考
- exifr official repository (opens in a new tab)Documents the metadata parser and supported EXIF, XMP, IPTC, ICC, and container fields.
- W3C File API (opens in a new tab)Defines browser access to user-selected local files.
关于Image Metadata的常见问题
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.
