Stirling PDF has just about every PDF tool you could want in one place. You can use it online or run it on your own computer or server so files stay private.

What you can do with it

  • Merge, split and rotate PDFs
  • Convert PDFs to and from Word and images
  • Compress big PDFs
  • Make scanned PDFs searchable with OCR

Good to know

If your files are private, self-host it rather than uploading them anywhere.
