Merge or split PDFs free, without uploading them?

Both jobs are built into software you likely already have. No uploads, no daily caps.

Merging

  • macOS Preview (free, built in): open the first PDF, show the thumbnail sidebar (View → Thumbnails), then drag other PDF files into the sidebar where you want them. Save. That’s the whole workflow, and almost nobody knows it’s there.
  • Windows: PDF24 Creator or PDFgear (free desktop apps, no watermark, fully offline). PDF24 in particular is ad-free and common in offices.
  • Any OS: LibreOffice Draw can open and rearrange PDF pages. It’s clunkier, but it works everywhere.
  • Command line: pdftk or Ghostscript merge dozens of files in one line. That’s the right tool if this is a recurring batch job.

Splitting / extracting pages

  • macOS Preview: select pages in the thumbnail sidebar → drag them out to the desktop, or File → Print → PDF → Save as PDF with a page range.
  • Windows: Print → Microsoft Print to PDF with a page range (e.g. 12-30) creates a new PDF containing just those pages. Zero install.
  • PDF24 / PDFgear have proper split-by-page-range and split-every-N-pages functions.

When online tools are still fine: non-confidential files, one-off jobs. The free tiers of iLovePDF, Smallpdf, and Stirling-PDF are legitimate. Just know the daily caps, and note that Stirling-PDF can also be self-hosted. That gives you the whole online toolkit running locally with no limits at all, if you’re comfortable with Docker.

The rule of thumb: anything with client names, salaries, health data, or contracts stays offline. Everything else, use whatever is fastest.
