What ZIP to PDF accepts
The archive can contain PDFs, common Office and OpenDocument files, and supported images. Files are processed in archive order and combined into one PDF. Unsupported items are ignored; an archive with no supported files is rejected with a clear explanation.
Prepare the archive
Rename files with numeric prefixes when order matters, remove unrelated content and keep the archive below the stated limits. For manual page-level control, extract the files yourself and use Merge PDF. Use Organize PDF after conversion if pages need rearranging.
