What to check before you upload a PDF
Most online PDF tools are safe in the everyday sense: they use encrypted connections and promise to delete files after a few hours. The real question is whether your document should leave your device at all. For a menu or a flyer it hardly matters. For a contract, a payslip, a medical letter or anything under NDA, it might.
- Where is the file processed? On the company's servers, or in your browser on your own device.
- How long is it kept? Look for a stated deletion time in the privacy policy, and for exceptions such as signed documents.
- Which country handles it? Server location decides which data-protection law applies.
- Can you check the claim? With a browser-based tool you can open the Network tab in developer tools and see that no request carries your file.
Each comparison above quotes the other site's own policy pages and links to them, with the date they were read. Where a competitor does something better, such as Office conversion or desktop apps, the page says so. See also PDF tools that don't upload your files and tools for confidential documents.
