PDF merging — also called PDF combining or joining — is the process of taking two or more separate PDF files and combining them into a single, unified document. The resulting file contains all pages from all source files in sequence, with the original content, formatting, and quality fully preserved.
Compressfy's merge tool uses pdf-lib entirely browser-side. You select the PDFs in the order you want them merged, click Merge, and download your combined PDF — all in seconds, all for free.
Files are merged in the order you select them. The first file you choose becomes the first section, the second file follows, and so on. Select files carefully in the order you want them to appear in the final document.
After merging, you may want to compress the merged PDF to reduce its size, especially if it contains many images. You can also add page numbers to the merged document for professional presentation, or add a watermark to mark it as confidential or draft.
