How to Merge and Split PDFs in Your Browser — No Upload Needed

How to combine several PDFs into one, or pull out just the pages you need — processed safely inside your browser, without sending files to a server.

Sometimes you need to bundle a stack of contracts into one file, or pull just a few pages out of a long report. Most online PDF tools upload your files to a server for processing — which is a real concern when the documents are sensitive. When everything happens inside the browser, your files never leave your device.

Merging multiple PDFs into one

  1. 1Drop two or more PDFs into the file picker.
  2. 2Check the order — files are joined top to bottom.
  3. 3Hit run, and the result is saved as a single PDF.

TipIf the order matters, prefix your file names with 01_, 02_, and so on — sorting becomes trivial.

Extracting only the pages you need

If you only need pages 3–7 of a 40-page document, use page extraction. You can specify a range like 3-7, or individual pages like 1,4,9. The original stays untouched — only the parts you need become a new PDF.

Splitting every page into its own file

To break each page out into a separate PDF, use split by page. The results come down together in a single ZIP.

Why in-browser processing is safer

  • Files are never sent to a server, so there is nothing to leak.
  • No sign-up, no software to install.
  • Once the page is loaded, it even works offline.
