{"slug": "show-hn-remove-ai-metadata-offline-in-browser", "title": "Show HN: Remove AI Metadata Offline in Browser", "summary": "A browser-based tool called Free AI Wiper lets users inspect and remove supported AI provenance metadata — including C2PA manifests, Content Credentials, generator records and XMP provenance — from files locally without uploading them. The tool covers JPEG, PNG, WebP, AVIF, HEIC, BMP, GIF and TIFF images; PDF, DOCX, PPTX, XLSX, HTML, SVG and MD documents; MP4, MOV and M4V video; WAV, MP3, FLAC and M4A audio; and pasted UTF-8 text, and it states it does not detect or remove SynthID or other watermarks embedded in audio. Free AI Wiper says a clean result only means supported portable signals were not found after cleaning and does not prove how content was created, and that processing multiple files requires logging in.", "body_md": "Studio fieldnotes\n\nShared moments ago\n\nFile inspection\n\n3 traces found\n- C2PA manifest\n- Detected\n- Generator record\n- Detected\n- XMP provenance\n- Detected\n\nInspect and remove supported AI metadata, including Content Credentials and generator information.

No universal AI detector exists.\n\nIt removes detectable AI metadata and provenance such as Content Credentials, C2PA/JUMBF records, generator information and selected metadata supported by each file format.\n\nNo. The current cleaners process supported files and text inside your browser. The selected content is not uploaded.\n\nNo. A clean result means the supported portable signals were not found after cleaning. It does not prove how the content was created.\n\nNot 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.\n\nFor 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.\n\nFor supported image formats, the cleaner preserves the encoded image payload and removes container metadata. It does not recompress the visible pixels.\n\nImages, documents, MP4/MOV video, WAV/MP3/FLAC/M4A audio and text are available today. Nothing is uploaded and your original stays untouched.", "url": "https://wpnews.pro/news/show-hn-remove-ai-metadata-offline-in-browser", "canonical_source": "https://freeaiwiper.com/", "published_at": "2026-10-12 13:35:05+00:00", "updated_at": "2026-10-12 13:47:01.869874+00:00", "lang": "en", "topics": ["ai-tools", "generative-ai", "ai-ethics"], "entities": ["Free AI Wiper", "C2PA", "Content Credentials", "SynthID", "JUMBF", "XMP"], "also_reported_by": [], "alternates": {"html": "https://wpnews.pro/news/show-hn-remove-ai-metadata-offline-in-browser", "markdown": "https://wpnews.pro/news/show-hn-remove-ai-metadata-offline-in-browser.md", "text": "https://wpnews.pro/news/show-hn-remove-ai-metadata-offline-in-browser.txt", "jsonld": "https://wpnews.pro/news/show-hn-remove-ai-metadata-offline-in-browser.jsonld"}}
