Show HN: Remove AI Metadata Offline in Browser

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.

Inspect and remove supported AI metadata, including Content Credentials and generator information. Private metadata removal is optional. Your file stays on your device.

Log in to process multiple files.

Same image, different file

This demonstration uses the exact same visible pixels on both sides. Only the supported portable provenance surrounding the image changes.

A verifiable process

Read the file container and identify supported provenance without decoding or up it.

Remove only the selected portable AI and optional private information.

Inspect the rebuilt file again before making the download available.

File coverage

JPEG · PNG · WebP · AVIF · HEIC · BMP · GIF · TIFF

Content Credentials, generator records and optional private metadata.

PDF · DOCX · PPTX · XLSX · HTML · SVG · MD

Supported document properties, image metadata, XMP and markup provenance.

MP4 · MOV · M4V

Portable provenance and generator information without re-encoding.

WAV · MP3 · FLAC · M4A

Supported provenance and descriptive tags without re-encoding audio.

Paste · UTF-8 .txt

Inspect and selectively remove supported hidden Unicode characters.

The current cleaner runs in this browser. We do not receive the file, filename, extracted metadata or cleaned output.

Clear answers

We describe only what the file inspection can verify. No universal AI detector exists.

It removes detectable AI metadata and provenance such as Content Credentials, C2PA/JUMBF records, generator information and selected metadata supported by each file format.

No. The current cleaners process supported files and text inside your browser. The selected content is not uploaded.

No. A clean result means the supported portable signals were not found after cleaning. It does not prove how the content was created.

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.

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.

For supported image formats, the cleaner preserves the encoded image payload and removes container metadata. It does not recompress the visible pixels.

Images, documents, MP4/MOV video, WAV/MP3/FLAC/M4A audio and text are available today. Nothing is uploaded and your original stays untouched.
