Lossless Photo Privacy Sanitizer: Purge Prompts, GPS & C2PA Footprints
A free, client-side utility to losslessly strip sensitive prompt texts, ComfyUI workflows, GPS coordinates, and C2PA container manifests while preserving 100% original pixel quality.
Whenever you create artwork with Midjourney, ChatGPT, or capture photos on modern smartphones, the file carries hidden metadata. In many cases, this metadata includes your exact engineering prompts, private workflows, device serial numbers, GPS coordinates, and C2PA container tracking manifests.
Sharing these images publicly can expose your creative intellectual property (prompt theft) or reveal your real-world location and identity.
The Lossless Photo Privacy Sanitizer solves this problem cleanly. It operates 100% in your browser using pure binary chunk filtering, stripping every byte of sensitive metadata while leaving your visual pixels 100% bit-for-bit identical.

Drag and drop your photos into the workstation below to inspect and strip their hidden metadata headers in seconds.
Lossless Photo Privacy & Metadata Sanitizer
100% Client-Side • Purges Prompts, GPS, Camera Tags & C2PA Headers With Zero Quality Loss
What Gets Stripped vs. What Stays Intact
❌ What We Erase (Sensitive Leaks)
- Prompts & Parameters: Text chunks (
tEXt/iTXt) storing exact generation prompts and negative prompts. - Location & GPS: EXIF geotags recording physical coordinates.
- Device Identifiers: Camera serial numbers, hardware models, and capture timestamps.
- C2PA Tracking Manifests: Bloated container chunks (
caBX) logging user creation sessions.
✔️ What We Preserve (Quality & Integrity)
- 100% Lossless Pixels: We never recompress, blur, or degrade your original image resolution.
- Pure Color Fidelity: Exact RGB values and alpha transparency channels remain untouched.
- Ethical Transparency: We do not alter deep latent pixel watermarks (such as SynthID), ensuring visual sharpness and ethical provenance compliance.
Most online converters degrade image quality by drawing images to lossy canvases and re-saving them as compressed JPEGs. This tool reads the underlying binary structure, surgically removing only the metadata chunks while preserving the raw raster pixel blocks bit-for-bit.

All media rendering, chunk filtering, and asset bundling are processed locally inside your web browser’s sandboxed runtime using native Canvas and WebAssembly APIs. Zero bytes of your files, images, or metadata are transmitted to or stored on our servers.
This utility is provided for personal privacy hygiene, asset optimization, and development workflows. Users retain full responsibility for verifying output files and ensuring their content complies with applicable copyright, intellectual property, and content provenance regulations under EU jurisdiction.
