## Overview
Inspect, analyze, and completely scrub privacy-compromising EXIF, GPS geotags, camera serial numbers, and personal metadata from photos and audio recordings. 100% in-browser with zero uploads.

## Format Specifications
- **Category:** Media & Images
- **Supported Formats:** `EXIF`, `JPEG`, `PNG`, `WebP`, `TIFF`, `WAV`, `MP3`
- **Privacy Guarantee:** 0 bytes uploaded to remote servers. All computation executes locally in browser memory.
- **Compliance:** GDPR, HIPAA & SOC 2 Friendly (process sensitive payloads and PII directly on your local device).

## Technology Stack
- exifreader Metadata Engine
- Binary EXIF Strip Pipeline
- Web Audio API
- Waveform Visualizer

## How It Works
1. Image and audio files are read into Uint8Array binary buffers.
2. ExifReader parses EXIF, IPTC, XMP, and ICC metadata segments, extracting sensitive GPS coordinates, device serial numbers, and capture dates.
3. Scrubbing creates a clean binary copy by removing metadata application markers (APP1, APP2, etc.) while preserving raw pixel fidelity without recompression.
4. Web Audio API decodes audio files locally to display interactive waveforms and allow lossless trimming.

## Practical Use Cases
### Removing GPS Geotags Before Social Sharing
Strip exact home and workplace coordinates from smartphone photos before uploading to public websites and forums.

### Whistleblower & Investigative Privacy Protection
Erase camera serial numbers, lens IDs, and software signatures from evidence photos before publication.

### Real Estate & Corporate Photography Preparation
Clean embedded copyright, creator names, and GPS data from corporate marketing assets.

### Audio Clip Trimming & Audio Scrubbing
Trim voice memos and audio recordings down to essential segments without transmitting private voice samples to third-party servers.

## Frequently Asked Questions
### Does scrubbing metadata reduce image quality?
No. Unlike tools that re-compress images through a canvas, our lossless scrubbing removes the binary metadata headers directly, leaving image data bit-for-bit identical.

### What sensitive information is typically found in photo EXIF data?
Smartphone and camera photos typically contain exact GPS latitude/longitude/altitude, device serial number, capture timestamp, camera model, lens parameters, and software versions.

### Can I batch scrub multiple photos at once?
Yes. The batch tab allows you to drag and drop multiple images to inspect and download cleaned files in one workflow.
