什么是图片元数据?
图片元数据是嵌入在照片文件中的隐藏信息。这些数据由数码相机和智能手机创建。
EXIF 数据
EXIF 包括相机型号、镜头设置、拍摄日期和时间等详情。
GPS 和位置元数据
大多数现代智能手机会在您拍摄的每张照片的元数据中嵌入精确的 GPS 坐标。

Frequently Asked Questions
Does removing metadata change image quality?
The image is re-encoded to remove hidden EXIF and GPS data. Visual quality is kept close to the original, but the file is technically rewritten.
Is GPS location data removed?
Yes. Re-encoding through the browser removes embedded metadata, including location fields stored by many phones and cameras.
Are my photos uploaded?
No. Metadata removal runs locally in your browser, so Selected image contents are processed locally in your browser.
