It depends on which tool you use.
The Risk: Server-Side Processing
Most online compressors upload your files to their servers:
- Documents travel over the internet
- Company could read or store your files
- Data breaches could expose documents
The Safe Way: Client-Side Processing
Tools like FreeConversion use client-side processing — files are compressed in your browser and never leave your device.
How to verify:
- Compression works offline (turn off WiFi)
- No "uploading" progress bar
- Check network requests in browser dev tools
Red Flags
- Tools requiring account creation
- Excessive ads and pop-ups
- Long "upload" times
- Vague privacy policies
Best Practices
- Use client-side tools for confidential documents
- Never compress sensitive info on unknown websites
What About HTTPS?
Even with HTTPS encryption, server-side tools still receive your unencrypted files on their servers. HTTPS only protects data in transit.
