Overview
Image Optimizer (now listed on WordPress.org as Image Optimization) is Elementor’s standalone image compression plugin. It does not require the Elementor page builder, but it does need a connection to an Elementor account, because images are processed on Elementor’s servers rather than your own.
What it does
Uploads can be optimised automatically, the existing library processed in bulk in the background, or single images handled from the media screen. You choose between lossless and lossy compression, optionally convert to WebP or AVIF, strip EXIF data, and resize anything wider than a set maximum (1920px by default). Originals are backed up and can be restored per image, and you can pick which registered thumbnail sizes are processed to save credits. A dashboard shows credit usage with alerts at 80% and 100%.
Pricing model
Every feature is available on every plan; plans differ only in credits and maximum upload size. The free trial covers up to 200 image files (about 50 uploads with default sizes) with a 10 MB per-file cap. Paid annual plans such as Image Optimizer 30K raise the allowance and the cap to 25 MB, and credits reset yearly. Image optimisation is also included through the shared monthly credits of an Elementor One subscription. Elementor states Image Optimizer Pro purchases are non-refundable.
- Cloud processing, no server load
- Unlimited websites per subscription
- Simple, mostly automatic setup
Limitations
Converted WebP/AVIF files replace the media file rather than being served by browser negotiation, there is no CDN, lazy loading or custom folder support, and no WP-CLI. The free allowance is effectively a trial, and the WordPress.org rating is low, with many reviews complaining about the account connection and credit limits.
Best for Elementor customers, especially Elementor One subscribers, who want straightforward cloud compression without adding another vendor.
Best for: Elementor users who want simple cloud compression and format conversion bundled with their existing Elementor account or Elementor One plan.
Image Optimizer covers the compression basics well (two levels, WebP/AVIF, resizing, backups) and keeps the workload off your server. Its trial-sized free allowance, account requirement and lack of delivery features make it hard to recommend outside the Elementor ecosystem, where Elementor One credits make it effectively included.
Pros

- WebP and AVIF conversion included on all plans
- Backups of originals with per-image restore
- Processing happens on Elementor's servers in the background

Cons
- Free allowance is a small one-off trial (about 50 uploads)
- Requires connecting an Elementor account
- No browser-negotiated WebP/AVIF delivery, CDN or lazy loading
- No WP-CLI, custom folders or PDF support
- Paid Image Optimizer plans are non-refundable; low WP.org rating

How many sites use Image Optimizer by Elementor?
Free installs from WordPress.org, the vendor's own claim, and our estimate of paid installs.
Free version (WordPress.org)
1M+
Active installations reported by WordPress.org.
Vendor claim
1M+
Sites/users claimed on the vendor's website. source
Estimated Pro / paid installs
~53K
Our estimate, see method below.
How we estimated this: The vendor figure (1M+) is within WordPress.org's rounding of the free installs, so it says nothing about paid sites. About 1.5M free installs x 3.5% (the usual share of free sites that also run the paid version when a hosted service whose free tier is generous, lower for very large free bases) gives 52K. Likely range: 27K to 110K. This counts sites running the paid version, including sites whose licence has lapsed. Estimates are rough and based on public figures as of 14 Oct 2026.
