¿Cómo se modifica una página web antes de convertirla?

Puede modificar el HTML de cualquier página antes de capturarla como imagen, PDF o DOCX.

Para hacer esto, necesita leer el contenido de la página HTML utilizando un método apropiado del lenguaje de programación que esté utilizando. Una vez que haya hecho esto, modifique el HTML, cuyo ejemplo se muestra a continuación. Luego configure el parámetro de dirección en el mismo que se usó para leer el contenido. Esto garantizará que la página web se capture utilizando la misma URL, de modo que todos los recursos relativos se representen correctamente.

Java
Node.js
