Introducción a EXIF:

1. EXIF es un estándar ampliamente utilizado que permite incrustar metadatos en archivos de imagen JPEG y TIFF.

2. Los metadatos registran información detallada sobre la fotografía, como la hora y el lugar de la toma, la configuración de la cámara y el objetivo utilizados, el tiempo de exposición, etc.

3. La información EXIF resulta muy útil para fotógrafos, editores de imágenes y cualquier persona que desee conocer los antecedentes de una imagen.

4. Dado que los datos EXIF pueden contener información detallada sobre el lugar de la toma, e incluso a veces incluso datos personales del autor, existe el riesgo de que se filtre la privacidad del usuario.

5. Nota: Antes de compartir una imagen, se puede borrar la información EXIF para proteger la privacidad personal.

6. Nota: esta herramienta no envía las imágenes subidas al servidor, por lo que puede utilizarse con total tranquilidad.
