Need to combine several PDFs into one? Whether you're assembling a report, merging scanned pages, or packaging documents for submission, merging PDFs is one of the most common document tasks.

When Do You Need to Merge PDFs?

Common scenarios include: combining a cover letter with a resume, merging multiple scanned pages into one document, assembling chapters of a report, or packaging invoices for accounting.

How to Merge PDFs Online (Free)

Open Luleit's PDF merger, drag in your files in the order you want them, and click merge. The combined PDF downloads instantly. Your files never leave your browser — everything is processed locally.

Can You Rearrange Pages?

Yes. Most PDF merging tools let you reorder files before combining. If you need to rearrange individual pages within a PDF, use a PDF editor or splitter first, then merge the results.

Tips for Better Results

Make sure all PDFs have the same page orientation (portrait or landscape) for a consistent result. If file size is a concern, compress the merged PDF afterward to keep it manageable.
