PDF merging is the process of combining two or more PDF documents into a single file. Instead of sending multiple attachments or printing and scanning pages together, you can join PDFs digitally in seconds. The result is one cohesive document with all pages in the order you specify, making it easier to share, archive, or present.
People merge PDFs for many reasons: assembling reports from different departments, combining scanned contract pages, creating a single portfolio from multiple documents, or consolidating invoices and receipts for record-keeping. Whether you have two files or twenty, merging streamlines your workflow and keeps everything organized.
