How do I create nested bookmarks?

Use '#' for top-level chapters, '##' for sub-sections, and '###' for tertiary sections within your text.

Can I customize the page layout?

Yes, you can select between A4 and Letter sizes, toggle landscape mode, and adjust font size, line height, and margins.

What happens if I don't use headings?

The tool will generate a standard PDF, but the bookmark navigation pane will be empty as there are no headings to anchor the outline.

Is there a limit to the number of bookmark levels?

The tool supports up to 3 levels of nested outline entries, corresponding to H1, H2, and H3 headings.

Will the bookmarks work in all PDF readers?

Yes, the bookmarks are embedded using standard PDF formatting, ensuring compatibility with all major PDF viewers and browsers.
