Bunny Storage supports FTP access for easy file management using familiar FTP clients and workflows. This provides compatibility with most software and programming languages.
The FTP protocol is outdated and not as secure as newer protocols like HTTP. It may be vulnerable to Man-In-The-Middle attacks. We recommend using FTP only when other upload options are not available. Use the HTTP API for better security and performance. Connection settings
Find your exact connection details in the Access tab of your storage zone and select FTP. Standard settings:
| Setting | Value |
|---|
| Hostname | storage.bunnycdn.com |
| Port | 21 |
| Username | Your storage zone name |
| Password | Auto-generated (found in FTP & API Access tab) |
| Connection Type | Passive |
| Encryption | Not supported |
Regional endpoints
Use the appropriate endpoint based on your storage zone’s primary region:
| Region | FTP Endpoint |
|---|
| Frankfurt, DE | storage.bunnycdn.com |
| London, UK | uk.storage.bunnycdn.com |
| New York, US | ny.storage.bunnycdn.com |
| Los Angeles, US | la.storage.bunnycdn.com |
| Singapore, SG | sg.storage.bunnycdn.com |
| Stockholm, SE | se.storage.bunnycdn.com |
| São Paulo, BR | br.storage.bunnycdn.com |
| Johannesburg, SA | jh.storage.bunnycdn.com |
| Sydney, SYD | syd.storage.bunnycdn.com |
Using FileZilla
- Open FileZilla (or your preferred FTP client)
- Enter your connection settings:
- Host: storage.bunnycdn.com
- Username: your-zone-name
- Password: your-storage-password

Common errors
ECONNREFUSED - Connection refused by server
This error occurs when using an invalid port. Verify you are connecting via port 21.
331 Username ok, need password
Your connection password is incorrect. Check your password in the FTP & API Access tab of your storage zone.
Connection timeout
Ensure you are using Passive mode in your FTP client settings. Some networks block active FTP connections.
Rate limits
FTP connections are subject to the same limits as HTTP API uploads:
- Maximum 25 concurrent FTP connections per IP
- Maximum 50 concurrent uploads per storage zone
- Maximum 100 concurrent connections per IP (across all protocols)
See the Limits page for more details.
