Lighter WordPress media, without the plugin bloat
WordPress media libraries fill up with full-resolution JPEGs and PNGs that drag down every page. Optimagio audits your site, bulk-optimizes existing media to WebP and AVIF, and keeps new uploads light — so your theme stays fast without piling on heavy plugins.
- Audit your live WordPress URL for image debt
- Bulk-convert the media library to WebP/AVIF
- API workflow to optimize new uploads
Real product capability — not a placeholder.
The most common WordPress speed problem is images
Themes, page builders, and stock photography make it easy to publish enormous images. Combined with WordPress generating multiple sizes per upload, media is usually the largest contributor to a slow WordPress site and a poor Largest Contentful Paint score.
Audit first, then fix at scale
Run a website image audit on your WordPress URL to see exactly which assets are oversized, in a legacy format, or likely your LCP image. Then bulk-optimize: export your media, run a batch to convert and resize, and re-upload the lighter set — or drive optimization through the API so new uploads are handled automatically.
A practical WordPress workflow
Live-site audit
Scan your published URL and get a ranked list of the heaviest images and likely LCP candidate.
Media-library bulk
Convert your existing library to WebP/AVIF in batches of up to 50,000 files.
Right-sizing
Resize oversized originals so WordPress isn’t generating sizes from 4000px source files.
API automation
Optimize new uploads via the API to keep the library light over time.
Fix-pack hand-off
A replacement-map CSV/JSON makes swapping URLs straightforward.
Privacy options
Strip EXIF by default, or keep it where licensing requires.
Right-sized for most WordPress sites
Starter at $9/month optimizes 10,000 images with 50 GB bandwidth and 5 GB storage — plenty for a typical blog or business site. Step up to Pro for large media libraries.
Frequently asked questions
How do I optimize images on WordPress?
Start by auditing your live URL to find the heaviest assets, then bulk-optimize your media library to WebP/AVIF and resize oversized originals. You can run batches from the dashboard or drive optimization through the API for new uploads.
Why is my WordPress site slow?
On most WordPress sites the largest cause of slow loading is oversized, unoptimized images — especially when full-resolution photos are uploaded and WordPress generates multiple sizes from them. An image audit pinpoints the worst offenders.
Will optimizing images improve my LCP?
Usually. The theme or hero image is frequently the Largest Contentful Paint element; converting it to WebP/AVIF and resizing it to display size lowers its byte weight and improves LCP.
