About CloudSync Master
From the official readme · v2.1.8Description
VERSION 2.0 – COMPLETELY REBUILT! CloudSync Master has been rebuilt from the ground up with a new setup wizard, 10 cloud providers, powerful integrations, and cross-provider migration.
Your slow-loading images are costing you visitors and sales. Studies show that 53% of mobile users abandon sites that take longer than 3 seconds to load. Every second of delay reduces conversions by 7%.
CloudSync Master offloads your WordPress media to cloud storage and serves it via global CDN – delivering lightning-fast page loads that keep visitors engaged and improve your Google rankings.
The best part? Unlike competitors charging $99+/year, CloudSync Master gives you 10 cloud providers, one-click migration, and zero egress fees – completely FREE.

Frequently asked questions
Which cloud provider should I choose?
For zero bandwidth costs: Cloudflare R2 or Wasabi – both have no egress fees For enterprise reliability: Amazon S3 or Google Cloud Storage For simplicity: DigitalOcean Spaces – straightforward pricing For large archives: Backblaze B2 – very affordable storage For self-hosted: MinIO – run your own S3-compatible storage

Product images are the #1 bandwidth consumer on e-commerce sites. CloudSync Master offloads all your product images to cloud storage automatically. Benefits for WooCommerce: – Faster product pages = higher conversion rates – Handle Black Friday traffic without crashes – Reduce hosting costs as your catalog grows PRO Feature: Secure signed URLs for digital downloads prevent customers from sharing download links.
Can I migrate from WP Offload Media?
Yes! CloudSync Master can automatically detect and import your settings from WP Offload Media, Media Cloud, and WP-Stateless. Look for the migration notice in your admin.
What about my existing media files?
The FREE version offloads new uploads automatically. Your existing files stay on the server. PRO Feature: The Media Library Scanner bulk uploads your existing media to cloud storage.
Will this slow down my site?
No – it speeds it up! Media is served from CDN edge locations closer to your visitors. Uploads happen in the background without affecting page loads.
What happens if I deactivate the plugin?
Your files remain in cloud storage. URLs will revert to local paths (if files still exist locally) or you can keep using cloud URLs.
Does this help with server migration?
Yes! When your media is in cloud storage, migrating to a new host is much easier – just move your database and code. No need to transfer gigabytes of media files. Your cloud URLs keep working immediately.
Is cloud storage safer than my server?
Much safer. Cloud providers like AWS, Google Cloud, and Cloudflare automatically replicate your files across multiple data centers. If your server gets hacked or crashes, your media is safe. Cloud storage is enterprise-grade backup built-in.
Can I use a CDN with this?
Yes! Configure a custom CDN domain in your account settings. Works with CloudFront, Cloudflare CDN, BunnyCDN, and others.
Does this work with multisite?
Yes. CloudSync Master is fully compatible with WordPress multisite networks.
Is Cloudflare R2 really free?
R2 has zero egress fees – you only pay for storage ($0.015/GB/month). The free tier includes 10GB storage and 10 million reads per month.
How is this different from WP Offload Media?
CloudSync Master offers: – 10 providers vs 3 –
What file types are supported?
All WordPress media types: images (JPG, PNG, GIF, WebP, SVG), videos (MP4, WebM), documents (PDF), and any other uploads.
Changelog
Bug fix: Improved handling of broken AWS permissions and files uploaded manually without standard wp-content/uploads path prefix.
2.1.8
- Fixed deleting a file from the Media Library leaving it behind in cloud storage when “Delete local file after upload” was enabled. The original and every generated thumbnail stayed in the bucket forever, so deleted media kept adding to your storage bill. Deleting a file now removes it and all of its sizes from the bucket, whether or not the local copy is still on the server.
- Fixed the account edit screen failing to load on sites where the plugin starts up late, which could leave the settings page blank instead of showing the form.
- Fixed media URLs breaking while migrating between two cloud accounts. Files that had not moved to the new bucket yet could be served from a mixed-up address that belonged to neither account, showing broken images. Files still in the previous bucket are now served correctly from that account until they are copied across.
- Kept the free edition’s shared code in sync with CloudSync Master PRO 2.1.8.
2.1.6
- Fixed a PHP 7.4 compatibility regression introduced in 2.1.5: on PHP 7.4 sites, media files could silently fail to offload to the cloud and stay on local storage after the bundled HTTP library was updated. Offloading now works reliably on PHP 7.4 and newer.
- Kept the free edition’s shared code in sync with CloudSync Master PRO 2.1.6.
2.1.5
- Added the “Fetch Missing Files From URL” option to the Upload Behavior settings. This is a CloudSync Master PRO feature: when a media file can’t be read from disk during offloading — for example on some managed hosts, with externalized media, or when files were already removed locally — PRO downloads the file from its public URL and offloads that copy so offloading still works. The option appears here as a PRO upgrade.
- Kept the free edition’s shared code in sync with CloudSync Master PRO 2.1.5.
2.1.4
- Improved compatibility when the CloudSync Master PRO add-on is also active — the free edition now reliably steps aside so the PRO edition’s most up-to-date shared code is always used. This prevents rare version-mismatch problems (including potential fatal errors) that could otherwise occur after updating only one of the two plugins.
2.1.3
- Fixed large media uploads (videos, multi-megabyte images, archives) silently failing when a single TLS hiccup interrupted one chunk mid-stream — the plugin now recognizes “cURL error 56” (LibreSSL bad record mac), “cURL error 55” (broken pipe), and similar transient network errors as retryable and retries them automatically with exponential backoff, instead of giving up after the first failed chunk and leaving the file unoffloaded
- Fixed multipart uploads (files larger than 5 MB) cascading-failing on shaky connections — previously, when one chunk failed, the plugin immediately aborted the whole upload session, causing every other in-flight chunk to fail with a 404; chunks are now allowed to finish their retries before the session is aborted
- Added a configurable concurrency cap for multipart upload chunks (default 3) to reduce parallel TLS pressure on hosts where SSL stability is the limiting factor
- Fixed customers upgrading from older versions losing all upload functionality when their stored settings predated the active provider configuration field — the plugin now backfills it automatically on first load, preferring the database-defined account, so uploads keep working after upgrade instead of silently staying on local storage
2.1.2
- Fixed admin page slowdowns caused by malformed attachment paths that triggered expensive cross-provider lookups on every upload queue scan — attachments with unresolvable paths are now detected and skipped early, eliminating hundreds of unnecessary database queries per queue cycle
- Fixed file offloading on Flywheel-hosted sites and other “sibling layout” WordPress installs (including Bedrock/Roots) where the content directory lives next to the WordPress core directory — previously the plugin computed cloud storage keys against the wrong filesystem anchor, producing unreachable keys so uploads either failed or the queue would never drain
- Fixed embedded URL extraction to correctly handle both local paths (mangled by get_attached_file) and URLs (mangled by wp_get_attachment_url) by matching the last http(s):// occurrence
- Fixed Edit Account form field names for Cloudflare R2 Quick Setup and Google OAuth — the form now submits canonical field names in all auth-mode branches, fixing R2 Quick Setup Public URL not saving correctly
- Inactive auth-mode inputs are now disabled so browsers do not submit stale values when switching between Quick Setup and API-keys (or OAuth and Service Account) modes
- The storage provider is now locked once an account is saved — the provider selector is greyed-out on existing accounts and a provider change is rejected on save to prevent breaking uploaded files and links
- Fixed provider switching while adding a new account — it no longer falls back to a full page reload that discarded unsaved fields, and a previous Test Connection result is cleared when switching providers
- Cloudflare R2 custom domain entered without a scheme (e.g. cdn.example.com) is now automatically normalized to https:// on save
- Existing Google OAuth accounts stored under a legacy key are migrated automatically on first edit — no action required after upgrading
- Cached bucket health status to skip repeated network probes on unreachable accounts, reducing background request overhead
- Updated compatibility with WordPress 7.0
