Configure: S3-Compatible Object Storage

This guide explains how to integrate any S3-Compatible object storage with your WordPress site using the Media Cloud Sync plugin developed by Dudlewebs. It supports services like Cloudflare R2, Wasabi, DigitalOcean Spaces, MinIO, and many others.

This documentation is designed to help you successfully offload WordPress media files to scalable and performant cloud storage.

What Is S3-Compatible Storage?

S3-compatible storage systems replicate the Amazon S3 API, allowing you to use the same connection method across multiple storage providers. The plugin integrates with any of these services using a consistent workflow.

Popular providers include:

• Cloudflare R2
• Wasabi
• MinIO
• Backblaze B2
• Scaleway
• Linode
• IDrive E2
