KAZCODE Universal Storage
Safe WordPress media offload and storage migration
Offload your Media Library to S3-compatible storage. Restore when needed. Move between providers with resumable transfers and verified cutover, while WordPress keeps control of attachment records and metadata.
Free · GPLv2+ · WordPress 6.7+ · PHP 8.3+ · Versioned ZIP · GitHub Release — v1.1.2
Free is distributed through WordPress.org. Pro is a separate add-on delivered through Freemius.
Built for serious WordPress media libraries
Editors keep using WordPress normally — Grid/List, the media modal, Featured Image and Gutenberg all continue to work exactly as before.
Store media binaries in object storage without replacing WordPress attachment records or metadata — WordPress stays the source of truth.
Existing Media Libraries move in recorded attachment batches, with per-object verification and retry — completed attachments do not need to be migrated again.
Bring remote media back to local storage on demand. The workflow is not one-way, and restore is never gated behind a paid upgrade.
Supported storage
Amazon S3, popular S3-compatible providers, and custom S3-compatible endpoints.
Designed for WordPress
Attachment posts and metadata always stay controlled by WordPress — this plugin never replaces the Media Library, it moves the binary files out from under it.
- Delivery URLs are generated from your current storage configuration rather than permanently stored — nothing is locked in
- Changing your CDN hostname or storage provider never requires rebuilding your WordPress attachment records
- Local hosting disk is no longer the only place your media can live — application hosting and media storage become separate concerns
For the implementation-level detail on how attachment paths and delivery URLs resolve, see URLs not updating in the docs.
Move WordPress media from S3 to R2 safely
PROMigrate between storage providers without replacing WordPress attachments or rebuilding your Media Library. KAZCODE Universal Storage Pro copies objects to the destination, verifies them there, and only then switches delivery to the new storage profile.
Amazon S3 → Cloudflare R2
- Independent source and destination credentials
- Resumable migration, per-object tracking
- Source delivery keeps serving your site until the destination is verified
- Verify-before-switch — delivery only changes after the destination is confirmed
- WordPress attachment metadata remains intact throughout

Built to be trusted with your media
- WordPress remains the source of truth for every attachment
- Every generated image size is tracked and verified independently, not just the attachment as a whole
- Local files are only removed after a successful remote verification — there is no setting that skips this
- Restore, verify and basic repair are Free capabilities, never gated behind a paid upgrade
- Batch migrations resume from recorded attachment progress, so completed attachments do not need to be migrated again
- Cross-provider migration (Pro) verifies the destination before delivery ever switches to it
- No KAZCODE-owned media proxy and no telemetry in Free — the plugin only talks to the storage endpoint you configure
Frequently asked questions
Does it replace the WordPress Media Library?
No. WordPress keeps attachment posts, metadata, titles and alt text. Only the binary files — originals and every generated size — move to object storage.
Can I restore media back to WordPress?
Yes. Restore downloads files back into wp-content/uploads on demand. It is a Free capability and is never gated behind Pro.
Does it support Cloudflare R2?
Yes, alongside Amazon S3, DigitalOcean Spaces, Wasabi, Backblaze B2, MinIO, and other S3-compatible endpoints.
Can I migrate from Amazon S3 to Cloudflare R2?
Yes — cross-provider migration with verify-before-switch safety is a KAZCODE Universal Storage Pro capability.
Is Free a trial?
No. Free is a complete, standalone product — one storage profile, full offload/migrate/verify/restore, no upload or time limits.
What happens if I deactivate Pro?
Deactivating Pro never deletes data or breaks media that's already being served. Existing profiles, credentials and delivery keep working; only new premium operations become unavailable until reactivated.
Does KAZCODE receive my media files or credentials?
No. The plugin only connects to the storage endpoint you configure yourself. There is no telemetry, tracking, or phone-home to any KAZCODE-owned service.
