How to merge PDF files online for free?
Combining multiple PDFs into one document takes under 10 seconds with FileSwiftly. Drag and drop your files, reorder them as needed, then download your merged PDF. No software installation, no account required.
When should you merge PDF files?
PDF merging is useful in many professional and personal scenarios: assembling an annual report from chapters written by different teams, consolidating monthly invoices into a single accounting file, combining separately signed contract pages, or preparing a client presentation portfolio. Our online PDF merger fully preserves layout, internal links, bookmarks, annotations, and metadata from every source document.
Merge PDF with drag-and-drop reordering
Before merging, reorder your files by drag and drop — the card sequence directly maps to the final page order in the merged PDF. The free plan supports up to 12 PDF files (each up to 50 MB). FileSwiftly Pro allows merging up to 50 files simultaneously, equivalent to an entire book in one operation.
What the merge preserves — and what it doesn't change
Our merge engine powered by Ghostscript guarantees complete document fidelity: identical fonts and layout, full-resolution images, intact tables and charts, clickable hyperlinks, and working bookmarks. Mixed page orientations (portrait and landscape) and different page sizes (A4, Letter, etc.) are fully supported within the same merged document.

FAQ
How many PDFs can I merge?
Up to 12 PDFs on the free plan, each up to 50 MB. FileSwiftly Pro supports up to 50 files per merge operation for high-volume document workflows.
Is page order preserved?
Yes. Pages from each PDF are inserted in the exact order of the source file, in the sequence you defined by drag and drop. No pages are skipped or duplicated.
Are bookmarks, links, and digital signatures kept?
Yes. Our merge engine preserves internal hyperlinks, bookmarks, annotations, and metadata from every source file. Digital signatures are also retained when they do not overlap between source documents.
Can I merge PDFs with different page sizes and orientations?
Yes. Each page keeps its original size and orientation (portrait, landscape, A4, Letter, etc.). The merged PDF can contain pages of mixed formats — perfectly valid and common in professional PDF documents.
