Overview
Images are the heaviest thing on your pages, and PageSpeed keeps telling you to "serve images in next-gen formats." Image Optimizer does it entirely on your own server: JPG and PNG convert to WebP locally via cwebp, Imagick or GD (with graceful fallback), so there's no external API, no per-image fees and no rate limits, ever.
The storefront emits proper `<picture>` tags with a WebP source and JPEG fallback plus native `loading="lazy"`, so every browser gets the best format it supports. Convert the back catalogue in bulk, keep new uploads converted via cron, or script it with the CLI.
Features
Every capability earns its place: built to solve a real merchant problem, not pad a feature list.
JPG/PNG → WebP on your own server via cwebp, Imagick or GD, no external service in the loop.
Unlike API-based optimizers there's nothing metered: convert a million images for free.

Works with
WebP source with JPEG fallback so old browsers still render perfectly.
loading="lazy" on below-the-fold images cuts initial page weight without JS.
Sweep the existing catalogue in bulk, keep new uploads converted on cron, or drive it from the command line.
Directly clears the 'serve images in next-gen formats' audit that drags LCP scores down.
Image Optimizer — setup guide
Step-by-step install & admin configuration, fully illustrated.
Open guide“Our technical team liked that Image Optimizer keeps the workflow inside Magento. In particular, native lazy loading works without sending assets to an external API. Installation and support were straightforward and well supported, and having source-code access made the extension easier to review for our environment.”

“After Image Optimizer was configured on our Magento store, the day-to-day workflow was clear. We especially value that images are converted to WebP locally on the server. The settings are easy to understand, and our team can manage the workflow without needing repeated developer assistance. It now replaces a task we previously handled manually.”

“We were dealing with large catalogue images slowing pages and external optimisation services adding recurring costs. After adding Image Optimizer, images are converted to WebP locally on the server and native lazy loading works without sending assets to an external API. The main difference for our store has been a smoother day-to-day workflow, fewer avoidable customer questions and less manual administration. It has been a strong fit for our Magento setup.”

“The core functionality does what we needed: images are converted to WebP locally on the server. It improves image delivery while keeping control and costs predictable. We had a small amount of configuration during the initial setup, which is why I would give it four stars rather than five. Overall, it is reliable and saves us considerable administrative time each week.”
