Merge PDF files online — free, fast, and private

Need to combine several PDFs into one document? FileStays' Merge PDF tool joins your files in seconds and lets you drag the pages into any order first. Because everything runs inside your browser, your documents are never uploaded to a server — they stay on your device from start to finish.

How to merge PDF files

  1. Click the upload box and choose two or more PDFs — you can select them all at once.
  2. Press Process pages to see every page as a thumbnail.
  3. Drag pages to reorder them, or remove any you don't need.
  4. Click Download PDF to save your combined document.
