Security and privacy when using online PDF tools

Important things to check before uploading documents to online PDF tools.

Choose tools that explain file handling

A trustworthy site explains whether files are stored temporarily, when they are deleted, and whether users can remove the result earlier.

Avoid uploading highly sensitive documents

For confidential documents such as medical data, financial records, or internal company files, consider offline processing or a private server.

Use passwords for certain documents

If a file needs to be sent to someone else, a password-protected PDF can help reduce accidental access. Send the password through a separate channel.

Quick tips

• Read the privacy policy before using a service.
• Delete files immediately after finishing when a delete button is available.
• Do not share download links with people who should not access the file.
