What you can do

🔗

Merge unlimited PDFs

Drop multiple PDFs in, drag them to reorder, click Merge. iLovePDF caps free users at 25; we don't cap at all.

✂️

Split by page, range, or group

One file per page, custom page ranges (1-3, 5, 7-10), or fixed groups (every 5 pages).

🖼️

Edit pages — drag to reorder

Open a PDF, see every page as a thumbnail, drag to reorder, delete pages you don't want, save.

📁

Drop a whole folder

Drop a folder of PDFs and they merge in filename order. Reorder by dragging if you need to.

⚡

No upload wait

Runs locally on your computer. No queue, no upload bar, no bandwidth cost. Often faster than the online tools.

📱

Works on your phone

Add to Home Screen on iPhone or Android — it installs like an app. No App Store needed.

Need more than a browser can do?

This free online version is the same idea as the Batch PDF Merger desktop app, minus what only a native app can offer:

  • Compress PDFs and renumber pages — desktop only.
  • Very large batches — a browser tab runs out of memory; the desktop app doesn't.
  • Native Mac & Windows app that works fully offline, no tab to keep open.

30-day free trial. Mac & Windows.

Turn off your Wi-Fi. It still works.

That's how you know nothing ever leaves your computer.

iLovePDF, Smallpdf, Adobe Acrobat — they all send your PDFs to a server. We don't. There's no test you can run on us that we'd fail.
