How to Merge Multiple PDFs into One for Free

When several PDF files related to the same topic pile up — like a full month's invoices or the chapters of a long report — merging them into one file makes archiving, sharing, and printing much easier than juggling dozens of separate files.

When do you need to merge PDF files?

Some of the most common cases: gathering monthly invoices or statements into one archive file, combining chapters or sections of a report written by different people separately, or bundling several documents (a resume, certificates, a cover letter) into a single file to submit somewhere.

Ordering files before merging

The final page order in the resulting file exactly matches the order of the files as they appear in the upload list, so be sure to reorder them by dragging before clicking the merge button if their original upload order doesn't match what you want.

Does merging affect quality or file size?

The merging process combines the files' pages as they are, without re-compressing them or changing their quality, so the result matches the original files' content exactly, and the final file's size will be close to the sum of the merged files' sizes. If the final size turns out too large, you can use the PDF compression tool afterward to shrink it.
