Find the media files slowing down WordPress.
Devenia Speed Optimization scans local WordPress image and video attachments, shows where oversized files are used, and reports what should be reviewed first.
Version 0.3.61 is available on WordPress.org. Requires WordPress 6.9+ and PHP 7.4+.
Speed problems need evidence.
The plugin gives site owners a local report before anyone starts replacing media, changing formats, or asking for paid optimization work.
Use it to find oversized images and videos before guessing. The scan checks local media, frontend usage, generated sizes, and rendered-size evidence, then turns that into a practical report.
The Problem
A WordPress page can feel slow because one visible image is far too large, a video was uploaded directly, or old media keeps being served at the wrong size.
Media libraries grow quietly
Large uploads, old campaign files, and unused generated sizes can sit in the site for years without anyone knowing which files still matter.
Page context matters
A file is not automatically a problem because it is large. The useful question is where it appears, how large it renders, and whether it affects important pages.
What It Checks
Images and videos
Configurable thresholds help identify attachments that are likely to slow down pages.
Usage evidence
The report shows content URLs, block references, featured images, frontend pages, and rendered-size checks where available.
Priority
Findings are scored so the site owner can review the most relevant media before spending time on low-impact files.
Local Report First
The local scan, report, settings, scheduled scans, backup, restore, and WP-CLI validation run on the WordPress site itself.
No Devenia connection required for reporting
A site can use the plugin for local diagnostics without connecting to Devenia or a payment provider.
Optional service actions
Paid Devenia service features are optional and require a site administrator to start or enable them.
Useful When
A site feels heavy
Start with a report instead of manually opening every media attachment.
Uploads keep returning
Scheduled scans can re-check after media, content, and theme changes.
Repair needs approval
Controlled repair plans, backups, restore checks, and redo handling keep replacement work reviewable.
Requirements
Requires WordPress 6.9+ and PHP 7.4+. Current public version: 0.3.61.
