Merge PDFs on iPhone & Android Free Online

Trying to email several PDFs from your phone? It's faster to combine them into one file. The Merge PDF tool at pdfjuggler.com is built with a touch-friendly interface that works perfectly on iOS and Android. This mobile PDF merger lets you combine PDF files on your phone without installing an app.

Step-by-step: Merge PDFs on mobile without an app

  1. Open the Merge PDF tool in Safari, Chrome or another mobile browser.
  2. Tap Select PDFs and choose files from your device, the Files app, or cloud storage.
  3. Drag thumbnails with your finger to set the correct order and rotate any page that looks sideways.
  4. Tap Merge PDFs and wait a moment while the file is created.
  5. The merged document downloads automatically—open it to confirm all pages look right.

Why merge on your phone?

  • Keep email threads tidy by sending a single attachment.
  • Quickly prepare documents while away from your computer.
  • Your files stay on your device; processing happens locally in the browser.

Compared with Smallpdf or iLovePDF, pdfjuggler merges files entirely on your device with no daily limits, whereas those services require uploads to their servers and may restrict free merges.

Need to tweak pages before combining? Use Organize to delete or reorder, or Compress to shrink the final file for easier sharing. For more control, learn how to split PDFs by page ranges or compress a PDF under 1MB before merging.
