核心要点
- EXIF 元数据由相机或手机写入 JPEG 文件的 APP1 标记段中。
- 照片常包含高精度 GPS 经纬度，极易暴露家庭住址与日常轨迹。
- 同时记录有相机型号、镜头参数、拍摄时间及设备唯一序列号。
- 通过 ArrayBuffer 二进制截断可在不重编码像素的情况下实现无损清理。
100% In-Browser & Local Execution

- GPS coordinates detector
- Camera model & date stripper
- Lossless binary ArrayBuffer scrubbing
- Zero file uploads
01.The Hidden Security & Privacy Risks of EXIF Geotagging
When taking photos with smartphones (iPhone, Android) or digital cameras, the device automatically records the exact GPS latitude, longitude, altitude, and timestamp into the image file’s APP1 header. Publishing these raw photos online exposes personal locations, daily routines, and device serial numbers to stalkers, adversaries, and data brokers.
02.Lossless Binary EXIF Scrubbing in Browser Memory
Unlike image re-encoding tools that decode pixels and re-compress them (causing generation loss), our EXIF Scrubber parses the raw binary ArrayBuffer, locates the JPEG APP1 / TIFF markers (0xFFE1), and cleanly strips the metadata segment while keeping 100% of image pixel data untouched.
How to Inspect and Strip EXIF Metadata
Step-by-step image metadata sanitization.
1
Upload or Drop Photo
Select an image file or drop it into the secure client-side dropzone.
2
Inspect Detected Metadata
View detected GPS coordinates, camera manufacturer, model, exposure settings, and timestamps.
3
Click Scrub Metadata
Instantly purge all EXIF segments from the binary image structure.
4
Download Sanitized Image
Save your clean, metadata-free photo with original visual quality intact.
Frequently Asked Questions
No. Binary scrubbing only removes metadata header segments; the underlying image pixels remain 100% bit-for-bit identical.
