なぜAI画像のメタデータを削除すべきなのか？
ChatGPTやMidjourneyで生成された画像には、隠された追跡データが含まれています。
Protect Commercial Prompt Privacy
AI image generators embed your full prompt string into image file chunks. Strip metadata so competitors cannot steal your secret prompt engineering techniques.
Remove C2PA & Digital Tracking Headers
Platforms like OpenAI, Google, and Adobe attach C2PA provenance headers. Our tool wipes all tracking manifests from PNG and JPEG files.
Disrupt Neural AI Detectors
Enable our pattern disruption engine to inject micro sub-pixel noise and DCT re-quantization, breaking high-frequency AI visual signatures for Hive and Illuminarty.
Safe for Stock & E-Commerce Platforms
Clean your AI artwork before selling on Etsy, Amazon, or stock photo platforms to avoid automated metadata flags and rejection.

Frequently Asked Questions
Everything you need to know about AI image metadata, C2PA headers, and prompt privacy.
What hidden metadata is stored inside AI-generated images?
Generators like DALL-E 3, ChatGPT, Midjourney, and Stable Diffusion embed prompt text, seed numbers, sampler settings, software signatures, and C2PA provenance manifests directly inside PNG/JPEG byte chunks (such as tEXt, iTXt, and EXIF APP1 headers).
How does this tool strip AI image metadata?
Our tool loads your image into an HTML5 browser canvas and re-renders the visual pixels onto a fresh, uncompressed image buffer. This process discards 100% of non-visual file chunks, headers, EXIF tags, and C2PA manifests.
How does the Enhanced AI Pattern Disruption feature work?
While metadata stripping erases file headers, AI image detectors (Hive, Illuminarty) analyze visual pixels for mathematical patterns. Our optional pattern disruption feature applies a 99.6% sub-pixel scale shift, micro-noise jitter, and DCT frequency re-quantization to break neural network detector fingerprints.
Are my images uploaded to any cloud server?
No! 100% of the image inspection and sanitization runs locally inside your browser's JavaScript memory. No image is ever uploaded to any server or third-party storage.
Does stripping metadata affect image quality?
No! Visual pixel quality is preserved at high resolution (95%+ quality encoding) while completely removing hidden text and tracking headers.
