Security Alert: In March 2025, the FBI warned about malware risks in online file converters. Browser-based processing eliminates these risks by keeping your files local.
The Privacy Problem with Popular PDF Converters
Most online PDF converters upload your files to their servers for processing. This creates several risks:
- Data exposure: Your sensitive documents are stored on third-party servers
- Privacy concerns: Files may be analyzed, logged, or retained longer than stated
- Security vulnerabilities: Server breaches can expose uploaded files
- Compliance issues: GDPR and other regulations require strict data handling

| Data Retention | Files stored temporarily | No server storage |
| Privacy Policy | Complex terms, data tracking | No data collection needed |

How Browser-Based Processing Works
Atelier's PDF tools use modern browser capabilities to process files entirely in your browser:
- Local Processing: JavaScript engines handle PDF operations in your browser
- No Upload: Files never leave your device - processing happens locally
- Instant Results: No network delays, immediate feedback
- Full Privacy: No servers involved means no data collection possible
Professional Use Cases
Browser-based PDF processing is especially critical for:
- Legal Documents: Attorney-client privilege requires absolute confidentiality
- Medical Records: HIPAA compliance demands strict data protection
- Financial Reports: Banking regulations prohibit third-party data sharing
- HR Documents: Employee information must stay confidential
- Business Intelligence: Competitive data cannot be exposed
