Combining multiple PDF files into a single document is a common task, but doing it wrong can result in poor quality or lost data. This guide shows you the right way to merge PDFs while maintaining quality and preserving important metadata.

Understanding PDF Merging

When you merge PDFs, you're combining separate files into one continuous document. The key is to use tools that don't re-compress or re-render the content, which can degrade quality.

Best Practices for Merging

Always merge PDFs in the order you want them to appear. Use tools that preserve bookmarks, links, and form fields. Avoid online tools that compress files unnecessarily.
