About Merge PDF

PDF merging (also called combining or joining PDFs) is the process of taking two or more separate PDF files and combining them into a single document. This is one of the most common PDF operations, useful for combining reports, contracts, receipts, scan pages, and any other documents that need to be unified.

Our free online PDF merger handles this process securely — no software installation needed, and your files are deleted from our servers within 1 hour.

Privacy first: Your files are processed using client-side JavaScript when possible. Files sent to our servers are encrypted with TLS and automatically deleted within 1 hour.
