I need to combine several PDFs into one file for a submission, and split a big scanned document into chapters. The online tools do it in seconds but they cap me after two files a day and I’d rather not upload work documents to a random site. What’s the best genuinely free way in 2026?
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 re-arrange PDF pages; clunkier but works everywhere.
- Command line:
pdftkor Ghostscript merge dozens of files in one line — 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. iLovePDF / Smallpdf / Stirling-PDF free tiers are legitimate — just know the daily caps, and note that Stirling-PDF can also be self-hosted, which 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 — keep it offline. Everything else, use whatever is fastest.
