Casos de uso

Verificar un índiceControlar que los marcadores existen, están en el orden correcto y apuntan a las páginas correctas.
Migración / transformaciónConvert a PDF outline into navigation for a web viewer, a mobile app, or a DMS.
Automatic table of contents generationReuse the structure of bookmarks to produce an HTML ToC or an index.

What you get

A tree-structured JSON of bookmarks: title, level, child/next/previous, style (bold/italic) if present.

The associated destinations (target page, coordinates/zoom) when they are resolvable.

Limits and points of attention

Many PDFs do not have bookmarks: in this case, the export will be empty, which is normal.
Some destinations are "named" or indirect: they may require partial resolution depending on the PDF.
En PDF cifrados, el acceso puede estar limitado.

Frequently asked questions

Is the outline and the "table of contents" the same?

The PDF outline is the side navigation. The table of contents can also be a page in the document.

Does the tool find the exact page?

Often yes. Depending on the PDF, the destinations may be indirect and harder to resolve.

¿Puedo reconstruir un índice en otro lugar?

Sí: el JSON sirve como base para recrear una navegación en otro formato.

Tip

For a clean migration, also export "PDF Pages → JSON": you will be able to validate that each bookmark destination points to an existing and correctly sized page.
