Free AI Wiper 上线浏览器端离线 AI 元数据清理工具
Show HN: Remove AI Metadata Offline in Browser
Free AI Wiper 发布浏览器端工具，可在本地检查并移除文件中的 AI 元数据与溯源信息，包括 Content Credentials、C2PA/JUMBF 记录和生成器信息，文件不上传、不重新压缩。
Private, browser-based file cleaning
Inspect and remove supported AI metadata, including Content Credentials and generator information. Private metadata removal is optional. Your file stays on your device.

See the hidden AI trail—not a fake visual makeover.
This demonstration uses the exact same visible pixels on both sides. Only the supported portable provenance surrounding the image changes.

Clear answers
What a clean result actually means.
We describe only what the file inspection can verify. No universal AI detector exists.
What does Free AI Wiper remove?
It removes detectable AI metadata and provenance such as Content Credentials, C2PA/JUMBF records, generator information and selected metadata supported by each file format.
Does the file leave my device?
No. The current cleaners process supported files and text inside your browser. The selected content is not uploaded.
Does cleaning prove a file was made by a human?
No. A clean result means the supported portable signals were not found after cleaning. It does not prove how the content was created.
Will a social network stop showing an AI label?
Not necessarily. Platforms may use portable metadata, their own detection systems or creator disclosure. Free AI Wiper only verifies the signals it can inspect in the file.
Does cleaning change audio quality?
For supported WAV, MP3, native FLAC and M4A files, the cleaner preserves the original audio bytes without re-encoding. Metadata cleanup does not detect or remove SynthID or other watermarks embedded in the sound.
Does cleaning reduce image quality?
For supported image formats, the cleaner preserves the encoded image payload and removes container metadata. It does not recompress the visible pixels.
Inspect your first file now.
Images, documents, MP4/MOV video, WAV/MP3/FLAC/M4A audio and text are available today. Nothing is uploaded and your original stays untouched.
