Unir PDF

Combina varios archivos PDF en un solo documento

pdfty's merge tool combines multiple PDFs into a single file in the order you choose. Upload, drag to reorder, click Merge — done. Bookmarks, page sizes, and fonts are preserved.

Useful for combining contracts, scanned receipts for expenses, separate report chapters, or course handouts into one shareable file. Up to 20 files at a time on the free plan.

We use the pikepdf library (built on QPDF) which preserves the structure exactly. No re-rendering, no quality loss. Files are processed server-side and deleted within 1 hour.
