About this tool

What this tool does

Merge PDF combines multiple PDF files—or selected page ranges—into one downloadable document. It fits office document workflows where you must combine PDF documents for submission to a portal, attach a single file to email, or package contract packaging for legal review.

Real-world use cases

  • Merge scanned PDF files from a copier into one chronological archive for audits or HR.
  • Building board packs, tenders, or grant applications from separate chapters and annexes.
  • Consolidating departmental reports before leadership review—without routing files through a cloud converter.

Privacy explanation

The PDFs you select are read in your browser tab. Stitching pages does not depend on uploading your documents to our servers; the merged output is built in memory and returned as a download.

Browser processing

Client-side libraries parse each PDF, apply your order and page ranges, and emit one buffer—so performance scales with your device RAM and CPU, not with a remote job queue.
