Things to consider

If a PDF contains sensitive data, prefer offline tools — many web-based 'free PDF' services upload your file. Check the privacy policy of any web tool before pasting in a contract.

Frequently asked questions

Are web-based PDF tools safe?

Many are; some aren't. For sensitive PDFs, use a desktop tool that processes files locally.

Can I edit a scanned PDF?

You'll need OCR first. Modern desktop tools include OCR; tesseract is the open-source option.
