Are online file converters safe to use?

Updated 5 min read

Quick answer

Many converters upload your file to their servers, so it depends who runs them and what they keep. For sensitive files, use a tool that works in your browser, and watch for fake download buttons.

Step by step

  1. Before adding a file, read where it is processed: on your device, or uploaded to a server.
  2. Check the privacy notice says how long uploaded files are kept and who runs the site.
  3. Look for https and the padlock in the address bar.
  4. After converting, download from the tool’s own button, not from adverts nearby.

Warning signs

Several big green Download buttons on one page, which are often adverts.

Asking you to install an app or extension to get your file.

No company name, no privacy notice, or a notice that says files may be used for other purposes.

Asking for an email address before you can download.

Tips

  • Be extra careful with passports, bank statements, payslips and medical letters.
  • Never install software or a browser extension just to convert one file.
  • Every FilePDQ tool that is available today runs in your browser: files stay on your device.

If something goes wrong

I already uploaded something sensitive to another site.

Look for a delete option or a contact address in its privacy notice and ask for deletion. If the file held bank or ID details, keep an eye out for phishing messages.
