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 to merge PDF files?
PDF merging is useful in many scenarios: assembling an annual report from separate chapters, consolidating monthly invoices into one accounting file, combining separately signed form pages, or preparing a presentation portfolio. Our online PDF merger preserves layout, internal links, bookmarks, and metadata from each source document.
Merge PDF with page reordering
Before merging, you can reorder files by drag and drop. The card order matches the final page order in the merged PDF. The free tool supports up to 12 PDF files, each up to 50 MB. FileSwiftly Pro allows merging up to 50 files at once.
