What Merge PDF does
Merge PDF is a free online service that combines multiple PDF documents into a single file without requiring registration or adding watermarks. Users upload separate PDFs, arrange them using drag-and-drop tiles, and click Merge to concatenate the pages top-to-bottom into one ordered document. The interface preserves the original fonts, layout, and images from each source file, producing a unified PDF suitable for sharing reports, lecture notes, or legal documents. The site supports uploading from a computer, Google Drive, or Dropbox, and offers optional advanced settings with default configurations recommended for most users.
