LightMoving UTF8MB4 Converter helps modernize older WordPress databases that still use latin1, utf8, or other non-utf8mb4 collations.

The plugin scans your WordPress database tables, identifies tables that are not using utf8mb4, and provides a safe administrator-controlled conversion workflow.

Features include:

Database charset and collation scan
WordPress table scan using the active table prefix
utf8mb4 server capability detection
Backup confirmation workflow
Required CONVERT confirmation step
Individual WordPress table conversion
Clean conversion success logging
Responsive modern admin interface
Direct Tools link from the Plugins page
No automatic conversion on activation

This utility is especially useful for:

older WordPress sites
migrated websites
legacy hosting environments
Themify and older builder installs
emoji and 4-byte character support warnings
multilingual WordPress environments

Safety Features

No automatic conversion on plugin activation
Administrator-only access
Backup confirmation checkbox
Required CONVERT confirmation text
Converts only tables using the active WordPress table prefix
Displays current database charset and collation
Displays current table engine and collation
Converts database default charset/collation
Converts WordPress tables individually

Important

Always create a complete database backup before converting database tables.

Large tables may require additional time depending on hosting resources. Conversion operations may temporarily lock tables while MySQL or MariaDB processes ALTER TABLE operations.
