TechnoHelps Image Optimizer

TechnoHelps Image Optimizer generates WebP versions of supported JPG and PNG Media Library files on your own server. Original files are preserved. The plugin includes bulk processing, individual optimization, Media Library integration, dynamic Custom HTML/JavaScript popup handling, local WebP verification and repair, configurable image quality, scheduled scans, and reports.

Image conversion uses supported PHP image editors available on your own WordPress hosting. No API key, paid external service, customer account, or image credits are required.

WebP verification and repair workflow

A bulk job marked complete is not proof that every generated thumbnail has a valid WebP file. The WebP Verification screen separately inspects the expected local WebP sidecars for each supported original image and registered thumbnail. Missing or incomplete variants can be queued for repair. Results distinguish local file verification from browser delivery; the latter depends on the site configuration.

Custom HTML and popup workflow

WordPress themes and custom-built popups may insert image URLs after page load. Alongside conventional WordPress image markup, the optional dynamic delivery handler attempts to map locally available WebP variants for supported dynamically inserted images and inline backgrounds. When a mapping is unavailable, the original URL remains in use. JavaScript rewriting cannot guarantee that the original image was not already requested, and stylesheet-based backgrounds may require server rules.

Selected image workflow

Use the native WordPress Media Library picker inside the plugin dashboard to optimize only the JPG/PNG attachments you select. Individual results include expected vs verified WebP variants, so you do not need to manually open every image to confirm the file-level conversion status.

Features

• Create WebP variants for JPEG and PNG uploads with compatible local encoder.
• Optimize a single image or multiple selected Media Library items.
• Queue older Media Library images using server-friendly processing batches.
• Verify converted WebP originals and thumbnails; identify missing variants and queue repairs.
• Preserve JPG/PNG original files and restore by removing generated WebP sidecars.
• Support Picture/HTML delivery and optional server rewrite rules; best-effort handling for dynamic JavaScript popups.
• Configure lossy WebP quality independently for photos and graphics.
• Scheduled scans, custom folders restricted to the uploads directory, reports and WP-CLI.

Please note: frontend delivery depends on theme, hosting, and caching configuration. The plugin never guarantees that every JavaScript or CSS background image is delivered as WebP. The local encoder must support WebP.

Privacy

Image compression and WebP conversion run on the site’s own server. No user images or usage telemetry are sent to TechnoHelps or a third-party compression API. The plugin includes an optional administrator-initiated support link. For the dynamic frontend WebP delivery feature, the browser may make same-site requests to WordPress admin-ajax.php to resolve local image URLs.
