When you need to quickly send a file to colleagues or clients without creating accounts, managing email attachments, or dealing with complex cloud storage workflows—free temporary file upload with no signup required is the most efficient solution. tfLink is designed for exactly these scenarios: supporting 100MB single file uploads, global CDN delivery, QR code sharing, and providing API/CLI tools, with anonymous uploads automatically cleaning up after 7 days.

Why Choose Temporary Upload (3 Key Benefits)

Save Time

No account registration needed—drag and drop your file and get a download link instantly. Perfect for one-time file transfers and quick collaborations.

Privacy & Lightweight

Don't want long-term storage, cloud quotas, or permanent records? Anonymous temporary uploads provide better privacy protection and are more secure for one-time transmissions.

Developer-Friendly

Provides comprehensive API & CLI support, making it easy to integrate into automation workflows (CI/CD, automated scripts, etc.).

Quick Start (Web + QR Code)

1. Open https://tmpfile.link/, drag or paste your file
2. System automatically generates download link and QR code for direct sharing
3. Anonymous uploads automatically delete after 7 days; registered users get extended retention periods

API / CLI Examples (Developer-Friendly)

curl Upload

curl -F "file=@/path/to/yourfile.zip" https://tmpfile.link/api/upload \
  -H "Accept: application/json"

Response Example (JSON):

{
  "downloadLink": "https://d.tmpfile.link/public/2025-09-18/xxxx/yourfile.zip",
  "fileName": "yourfile.zip",
  "size": 12345678,
  "type": "application/zip"
}

Note: The platform supports POST /api/upload with multipart/form-data and returns downloadLink for direct sharing.

Quick Download Link in Scripts

DL=$(curl -s -F "file=@./report.pdf" https://tmpfile.link/api/upload | jq -r .downloadLink)
echo "Download link: $DL"

Best Practices (Security & Efficiency)

• For sensitive materials: Encrypt locally first (zip with password / gpg) before uploading
• File naming: Avoid including sensitive information in filenames (like ID numbers, contract numbers)
• Long-term retention: For files needing permanent storage, use registered user uploads or migrate to long-term storage solutions
• File size limit: 100MB maximum for anonymous uploads

Advanced Usage Scenarios

CI/CD Integration

Integrate temporary file uploads into your continuous integration workflows:

# GitHub Actions example
- name: Upload build artifacts
  run: |
    DOWNLOAD_URL=$(curl -s -F "file=@./dist/app.zip" https://tmpfile.link/api/upload | jq -r .downloadLink)
    echo "Build available at: $DOWNLOAD_URL" >> $GITHUB_STEP_SUMMARY

Team Collaboration

Share large files instantly with team members without cluttering shared drives or email inboxes. Perfect for:

• Design mockups and prototypes
• Test builds and QA artifacts
• Documentation and reports
• Meeting recordings and presentations

Security Considerations

While tfLink provides secure HTTPS transmission and automatic cleanup, consider these additional security measures:

• End-to-end encryption: For highly sensitive files, encrypt before uploading
• Access control: Share links only with intended recipients
• Time sensitivity: Use the 7-day auto-deletion as a security feature
• Audit trails: For compliance requirements, maintain logs of what files were shared and when
