Transfer files between Google Drive, Dropbox, OneDrive, pCloud, and WebDAV servers like Nextcloud without downloading them first. Our server-side transfer technology makes multi-cloud management simple, fast, and secure.
Sign up for free at cloudcombo.app. No credit card required for the free plan. Enter your email, create a password, and verify your email address. The entire registration process takes less than 2 minutes.
Navigate to Cloud Manager and connect your cloud storage accounts. We use OAuth 2.0 authentication, which means you log in directly through your cloud provider. Cloud Combo never sees or stores your passwords.
Access all your connected cloud drives from the unified file browser. Browse folders, search for files, view thumbnails, and see file details including size, type, and modification date across all your cloud accounts.
Choose files or entire folders from your source cloud storage. You can select multiple files at once. When you select a folder, all its contents and subfolders are automatically included, preserving the complete folder structure.
Select where you want to transfer your files. Choose any connected cloud storage account and browse to the specific folder where files should be placed. You can create new folders in the destination if needed.
Click "Start Transfer" to begin. Files are transferred directly from one cloud to another through our servers using streaming technology. You don't need to keep your browser open - transfers continue in the background.
Unlike traditional methods that download files to your computer and then upload them, Cloud Combo performs transfers directly between cloud providers on our servers. This is much faster and doesn't use your device's storage or bandwidth.
We use streaming technology to handle files of any size efficiently. Large files are transferred in chunks, allowing for pause and resume capabilities if network issues occur.
Transfers are processed as background jobs using Redis and Bull queue system. This means your transfers continue even if you close your browser or lose internet connection temporarily.
You can monitor transfer progress in real-time from the Transfer List page. Each transfer shows detailed status including files completed, files in progress, and any errors.
We use official APIs from each cloud provider: Google Drive API, Dropbox API, Microsoft Graph API for OneDrive, and pCloud API — plus the open WebDAV protocol for Nextcloud, ownCloud, Synology NAS, Koofr and other self-hosted storage. This ensures maximum compatibility, reliability, and security.
All file operations (read, write, delete) are performed through these official APIs with proper authentication and authorization at every step.
Your files are never permanently stored on our servers. During transfers, files are streamed through our system and immediately deleted once the transfer completes.
We only store metadata (file names, sizes, transfer status) needed to provide the service. All connections use SSL/TLS encryption, and access tokens are encrypted in our database.
