À propos de PDF Merger

Merging multiple PDFs into one document is essential for combining reports, assembling application packages, or collating contracts with their exhibits. Our merger lets you drag to reorder pages, select specific page ranges from each file, and merge up to 20 PDFs into a single clean output.

Comment l'utiliser

  1. Upload multiple PDF files.
  2. Drag to reorder the files in your desired sequence.
  3. Optionally select page ranges from each file (e.g., pages 2–5 of file 1).
  4. Click Merge and download the combined PDF.

Formule et méthodologie

PDF merging concatenates the page trees of multiple PDF documents into a single PDF object graph. Internal references (page numbers, bookmarks, named destinations) are remapped to the new sequential page numbers. Cross-document links are preserved or broken depending on whether destinations exist in the merged output.

Cas d'usage courants

  • Job applications: combining resume, cover letter, and portfolio into one PDF
  • Legal: assembling contracts with exhibits, schedules, and signature pages
  • Accounting: combining monthly statements into a single annual report
  • Real estate: combining purchase agreement, disclosure, and inspection report
  • Academic: combining thesis chapters into a single submission file

Questions fréquentes

Internal hyperlinks within a single source document are preserved. Cross-document links (a link in PDF 1 pointing to PDF 2) become broken after merging unless the tool remaps them — which most simple mergers do not. Bookmarks (the navigation panel) from each source document are typically preserved and nested under each file's original bookmark tree. Test navigation after merging for complex documents.
Our tool handles files up to 100MB each and up to 500 total pages. For very large merges (entire book collections or legal discovery packages), command-line tools are more appropriate: pdfunite (poppler), gs (Ghostscript), or Python's pypdf library. Professional tools like Adobe Acrobat Pro handle arbitrarily large merges but require a paid subscription.
