Informazioni su questo strumento
The Auto Bookmarks Generator brings absolute clarity to lengthy, unstructured PDF documents.
Scanning through books or booklets with no outline navigation is painful. This tool parses typographic hierarchies (such as font sizes and weights) along with regex rules (like "Chapter 1", "Section 1.1") to automatically deduce headings.
It then compiles and injects these headings directly into the PDF /Outline dictionary. Any standard viewer will then show a beautifully structured, multi-level navigation sidebar, backed by an interactive 3D outline tree preview.
Practical guidance before you use Genera Segnalibri
Best for real document workflows
Use Genera Segnalibri when you need a quick browser-based result without creating an account or sending routine documents through an unnecessary upload workflow. Technical manuals organizing is a common example: Auto compile multi-level chapters for standard guidelines, saving hours of manual indexing.
Privacy and file handling
EasyPDFNex prioritizes local processing in your browser. That means supported PDF operations run on your device, not in a public cloud queue. For sensitive files, review the output before sharing it, close the browser tab after downloading, and avoid processing documents you are not authorized to edit.
Quality checks after processing
After you build and inject, open the result and check page order, text readability, signatures, links, and form fields. If the source file is scanned, encrypted, very large, or damaged, try a related workflow such as bookmark, table of contents, interactive toc generator before repeating the task.
Start with a clean source file whenever possible. For Genera Segnalibri, the first step is usually "Provide unstructured PDF": Upload large brochures, academic papers, or ebooks lacking a catalog sidebar. This simple preparation step prevents most failed exports, missing pages, and formatting surprises.

Domande frequenti
Can it match custom chapter formats?
Yes. You can add custom regex patterns in the sidebar panel (e.g., `^Part\s+\w+`) to target unique layouts.
Will this affect the visual page presentation?
No. The tool only adds an internal structural bookmark catalog. The text and visual assets of the pages remain untouched.
How many bookmark levels are supported?
The tool supports deeply nested bookmark structures, allowing chapter, section, and subsection layouts.
