When Online File Conversion Is (and Isn't) Safe

Online file converters range from trustworthy to outright dangerous. Understanding what happens to your files helps you make informed decisions about which tools to use for which tasks.

When Online File Conversion Is (and Isn't) Safe

Low-Risk Files

Converting a public image or a non-sensitive document? The risk is minimal. Most legitimate services delete files within 24 hours.

High-Risk Files

Contracts, tax returns, medical records, source code, and any document with personal information should never be uploaded to an unknown online converter.

Check the Privacy Policy

Reputable services clearly state their data retention and deletion policies. If a service doesn't have a privacy policy, avoid it.

Use Offline Tools

For maximum safety, use browser-based offline tools. Your files never leave your device - there's no server exposure to worry about.
