getedgehq/strip-image-ai-metadata

Elimina metadatos C2PA y de generación AI de imágenes (PNG, JPEG, WebP) para eliminar etiquetas como "Generado por AI" / "ChatGPT" / "DALL-E" que plataformas como LinkedIn, Instagram y X muestran.

¿Qué es strip-image-ai-metadata?

Esta herramienta permite eliminar metadatos C2PA y de atribución AI de imágenes generadas por inteligencia artificial, como ChatGPT, DALL-E o Midjourney. Es útil para limpiar imágenes antes de publicarlas en plataformas que muestran etiquetas de atribución automática (LinkedIn, Instagram, X). El script preserva la calidad original de la imagen al no re-codificarla, solo elimina los metadatos incrustados. Soporta los formatos PNG, JPEG y WebP, y ofrece opciones para sobrescribir el archivo original o generar una copia con un nombre neutro tipo cámara. También incluye un modo de verificación automática para asegurar que los metadatos hayan sido eliminados correctamente.

Eliminar Metadatos AI de Imágenes

Plataformas como LinkedIn leen los metadatos C2PA incrustados por generadores de imágenes AI (ChatGPT, DALL-E, Midjourney, etc.) y muestran una etiqueta de atribución. Esta habilidad elimina esos metadatos sin re-codificar, preservando la calidad de la imagen.

Formatos soportados

  • PNG: elimina chunks caBX y chunks tEXt/iTXt/zTXt relacionados con AI
  • JPEG: elimina segmentos C2PA APP11 y segmentos APP1 (XMP/EXIF) relacionados con AI
  • WebP: elimina chunks C2PA y payload relacionado con C2PA

Uso rápido

Ejecuta el script incluido en una o más imágenes:

python3 scripts/strip_c2pa.py imagen.png      # elimina metadatos + renombra a IMG_YYYYMMDD_HHMMSS.png
python3 scripts/strip_c2pa.py imagen.jpg -o limpia.jpg
python3 scripts/strip_c2pa.py *.png

Por defecto, el script escribe una copia limpia con un nombre neutro estilo cámara (IMG_YYYYMMDD_HHMMSS.<ext>) en el mismo directorio y deja el original intacto. Usa -i/--in-place para sobrescribir el original, o -o para una ruta de salida explícita.

Flujo de trabajo

  1. Inspeccionar (opcional): Si el usuario no está seguro de si una imagen tiene metadatos C2PA, ejecuta:

    strings imagen.png | grep -i c2pa

    o lee los chunks PNG con Python para buscar caBX.

  2. Eliminar: Ejecuta scripts/strip_c2pa.py <ruta>. El script escribe una copia con nombre neutro por defecto e informa qué se eliminó.

  3. Verificar: El script escanea automáticamente la salida en busca de palabras clave C2PA/AI restantes y advierte si se encuentran.

Qué NO hace

  • No elimina marcas de agua visibles incrustadas en los píxeles.
  • No elimina metadatos EXIF estándar a menos que contengan palabras clave de atribución AI.
  • No re-codifica, por lo que el tamaño del archivo y la calidad de la imagen no cambian (excepto por los metadatos eliminados).

Cuándo re-codificar en su lugar

Si la plataforma aún muestra una etiqueta AI después de eliminar los metadatos, la atribución podría estar incrustada en los píxeles o almacenada en un formato no C2PA. En ese caso, usa ImageMagick para decodificar y re-codificar:

convert entrada.png -strip salida.png

Esto no tiene pérdida para PNG, pero puede causar una ligera pérdida de calidad para JPEG.

Individual skills in this repo

This repo contains 18 individual skills — each has its own dedicated page.

getedgehq/agent-evals

Build evals for an AI agent that already does real work. Use when someone asks "how do I know my agent is right", wants to test an agent before trusting it, compare models on cost versus quality, or turn production failures into tests. Walks from first tasks and yes/no verifiers, to isolated environments, to a trace-driven improvement loop.

getedgehq/cli-ux-review

Audit a command-line tool for user-friendliness — clear situation / next-step / options in every output, colour-highlighted runnable commands, no raw jargon, no silent hangs. Invoke for "CLI UX audit", "review my CLI", "is this CLI intuitive", or before any CLI release.

getedgehq/generate-image

Generate images with OpenAI GPT Image 2 via the Codex CLI, billed through the user's ChatGPT Plus subscription (no OpenAI API key, no per-image API cost). Use when the user asks to create, generate, or make an image, picture, illustration, icon, hero graphic, or concept art from a text prompt.

getedgehq/harness-first

Diagnose and fix an unreliable, expensive, or unsafe LLM agent by auditing its harness (golden set, judge, cost caps, data layer, action approvals, tracing) before blaming or swapping the model. Use when someone says an agent is "burning tokens", "hallucinating", "brittle", gives inconsistent answers, asks whether to switch to a cheaper/better model, or wants to ship an agent or prompt change to customers.

getedgehq/http-error-triage

Run before concluding anything from an HTTP error on a third-party API. Separates a real credential/entitlement problem from a CDN or WAF block, a wrong endpoint, or a client-signature ban. Use whenever an API returns 401/403/402/429 and you are about to say "the key is dead", "credits are exhausted", "the plan lacks access", or "we are rate limited".

getedgehq/linkedin-media-prep

Convert, crop, resize, and compress images and videos for optimal LinkedIn upload quality and file size. Use when the user wants to prepare a photo, image, or video for LinkedIn (profile picture, cover photo, post image, article featured image, post video, or video ad), optimize file size for LinkedIn, crop and resize for LinkedIn dimensions, convert HEIC/RAW/PNG/MOV to LinkedIn-ready JPEG or MP4, or mentions LinkedIn media requirements, specs, or limits.

Use for people discovery, LinkedIn or Sales Navigator search design, profile-list ranking, or provider filter translation.

getedgehq/rocketlist

Turn a CV into a shortlist of live startup roles from Rocketlist's public job board, including adjacent job titles the person would never have searched for, each with its published salary, the evidence for the fit, and a direct apply link.

getedgehq/security-audit-checklist

Run a comprehensive security audit across application code, cloud infrastructure, containers, CI/CD pipelines, and infrastructure-as-code. Covers privacy compliance, OWASP basics, secret leakage, API security, IAM misconfigurations, storage exposure, Kubernetes hardening, and network security. Use when the user asks to audit, review, or harden app or cloud security, check for secrets, scan for XSS/SQLi, verify security headers, review Terraform/CloudFormation, audit AWS/GCP/Azure configs, or perform any security-focused review.
