Your files and privacy are protected at every step on FunPDF. We've built our platform with security-first architecture to ensure your documents remain private and secure.
How We Protect Your Files
SSL/TLS Encrypted Connections
Every file upload and download uses HTTPS with 256-bit SSL/TLS encryption:
- All data transmitted between your browser and our servers is encrypted
- Same encryption standard used by banks and financial institutions
- Protects your files from interception during transfer
- You can verify the padlock icon in your browser's address bar
Client-Side Processing for Maximum Privacy
Many tools process files entirely in your browser:
Why this matters: Your files are processed directly in your browser's memory. No upload to servers means zero server-side storage and maximum privacy.
Automatic File Deletion
Files processed on our servers are automatically deleted:
Small Files (< 10MB) - Synchronous Processing:
- Processed immediately in server memory
- Result returned to you instantly
- Deleted within seconds after processing completes
- Never written to permanent storage
Large Files (10MB - 200MB) - Asynchronous Processing:
- Uploaded to encrypted temporary storage
- Processed by isolated background services
- Result stored temporarily for download
- Both input and output files deleted after 2 hours maximum
- Earlier deletion if you download the result
Failed Conversions:
- Files deleted immediately upon failure
- No retention for debugging or retry
- Re-upload required if you want to retry
No Permanent Storage Policy
FunPDF operates on a zero permanent storage principle:
- ❌ No long-term file storage
- ❌ No backup copies of your files
- ❌ No file history or versioning
- ❌ No recovery possible after deletion
- ❌ No access by FunPDF staff or administrators
What Data We Actually Store
We Store (Only What’s Necessary):
- Account basics if you choose to sign in (contact info plus authentication tokens)
- Usage counts required to enforce fair-use limits (never the actual file contents)
- Error logs stripped of document content
- Temporary async job records so you can resume downloads (auto-cleared after ~2 hours)
We Never Store:
- ❌ File contents or file names
- ❌ User accounts or personal information (no registration required)
- ❌ IP addresses linked to specific files
- ❌ Document metadata or contents
- ❌ Processing history tied to individuals
Data Flow Transparency
Client-Side Tools (Merge, Split, Watermark, PDF ↔ Images)
- You upload files to your browser's memory
- Lightweight in-browser PDF engines process files locally
- Result created in browser memory
- You download directly from browser memory
- Closing the tab clears all data
Server involvement: Zero. These tools work offline after page loads.
Server-Side Tools (Conversions, Compression, OCR, Encryption)
Small Files (< 10MB):
- File uploaded via SSL to server memory
- Secure backend service processes immediately
- Result returned via SSL
- File deleted from memory within seconds
Large Files (10MB - 200MB):
- File uploaded via SSL to encrypted temporary storage
- Job enters a protected processing queue
- A dedicated worker retrieves the encrypted file
- Processing happens inside an isolated environment
- Result uploaded back to secure temporary storage
- You receive a download link
- Files deleted after 2 hours or upon download
Security Measures for Server Processing
- Every conversion runs in an isolated environment so files never mix.
- Internal services authenticate and timestamp their requests to prevent tampering.
- Temporary storage uses encryption at rest, randomized names, and short-lived download links.
What We Don't Do With Your Files
We never:
- ❌ Share files with third parties
- ❌ Use files for AI training or machine learning
- ❌ Analyze file contents for advertising
- ❌ Sell or monetize your data
- ❌ Provide files to government or legal requests (we have nothing to provide)
- ❌ Keep backups or archives
Additional Privacy Protections You Can Use
For Highly Sensitive Documents:
1. Use Client-Side Tools When Possible
- Choose Merge PDF or Split PDF for local processing
- These tools never upload files to servers
2. Encrypt PDFs Before Upload
- Use Encrypt PDF to password-protect files first
- Upload encrypted version for conversion
- Decrypt after downloading result
3. Use Private Browsing Mode
- Open FunPDF in incognito/private window
- No local browsing history or cache
- Session cleared when window closes
4. Use VPN for Additional Privacy
- Masks your IP address from our servers
- Adds extra encryption layer
- Recommended for confidential business documents
5. Remove Metadata Before Upload
- Clean PDF metadata (author, company, creation software) before processing
- Prevents accidental information disclosure
Compliance and Standards
GDPR Compliant
- Minimal data processing (no personal data storage)
- No user tracking or profiling
- Automatic data deletion meets "right to erasure"
- No consent required (anonymous processing)
Industry Security Standards
- SSL/TLS encryption for all connections
- Secure cloud infrastructure with encryption at rest
- Regular security audits and updates
- Following PDF/A archival standards
Browser Security
Modern browsers provide additional security layers:
- FunPDF runs inside the browser’s sandboxed environment
- FunPDF cannot access files outside the browser tab
- No access to other websites or system files
- No ability to install software or malware
Safe for Sensitive Documents
FunPDF is safe for processing:
- ✅ Business contracts and agreements
- ✅ Financial documents and invoices
- ✅ Legal documents
- ✅ Medical records (client-side tools for HIPAA compliance)
- ✅ Personal identification documents
- ✅ Tax forms and sensitive paperwork
Recommendation: For maximum privacy with highly confidential files, use our client-side tools (Merge, Split, Watermark, PDF to Images, Images to PDF) which never upload files to servers.
