ADOC to PDF: What's the Best Way to Convert Without Losing Formatting?

Hello everyone.

I've been working on a technical documentation project using AsciiDoc, and now I need to share the final output with clients who prefer PDF files. I've tried a couple of online tools, but the results were inconsistent, especially with tables, code blocks, and embedded images not rendering correctly.

I'm looking for a reliable method to convert ADOC to PDF while keeping the original structure, fonts, and formatting intact. Ideally, I'd like something that works well for longer documents with multiple sections and cross references. Has anyone found a tool or command line approach that handles this conversion smoothly? Any recommendations for free or paid solutions would be appreciated.

Thanks in advance for your help and suggestions.
