The plugin runs on your own server using available PHP image libraries. It does not send image files to an external service, require a cloud account, or lock conversion features behind a premium plan. #### Key features * Convert JPG, JPEG, and PNG files during upload. * Convert existing JPG, JPEG, and PNG media files one at a time from the Media Library. * Bulk convert existing JPG and PNG media files in small batches from the imagIn settings page or directly from the Media Library. * Choose the output format: WebP or AVIF. * Keep the original file, replace it after conversion, or move it to a backup folder. * Set separate quality levels for WebP and AVIF. * Check available PHP memory before converting large images and show an actionable message when more memory is needed. * Check server support for GD, Imagick, WebP, and AVIF. * Store conversion metadata on each attachment. * Show conversion status in the Media Library. * Show progress and a clear completion result during bulk conversion. * Update image URLs in page content and builder data after conversion, including Elementor data. * Use local server libraries only. #### Local-first image conversion imagIn is designed for site owners who want a simple conversion workflow without connecting WordPress to an external optimization platform. Conversion support depends on the image libraries available on your hosting server. If your server does not support WebP or AVIF through GD or Imagick, the plugin will show the capability status and skip unsupported conversions safely. #### Original file handling You can choose how imagIn handles original images after a successful conversion: * Keep the original file and its WordPress image metadata. The converted file is stored in uploads without creating a second Media Library attachment. * Replace the original file with the converted file. The converted file becomes the main Media Library asset used by pages and templates that reference that attachment. * Move the original file and generated source sizes to a backup folder inside uploads. If existing pages depend on a direct JPG or PNG file URL, keep `Update page image references` enabled before using any handling mode. Matching URLs in WordPress content and builder metadata will be updated after a successful conversion. Keep original remains the safest choice for the original attachment and its metadata, but URLs stored outside WordPress content or metadata still cannot be identified automatically. When `Update page image references` is enabled, imagIn also updates matching image URLs in post content, excerpts, and post metadata used by page builders. This helps Elementor and other builders switch to the converted file without replacing each image manually. ### Privacy imagIn processes images locally on your WordPress server. The plugin does not send image files, site data, or usage data to an external API, CDN, cloud service, or third-party optimization platform. ### Support imagIn is completely free and does not include premium features, usage limits, or cloud requirements.

Upload the `imagin-webp-avif-converter` folder to the `/wp-content/plugins/` directory, or install the plugin through the WordPress Plugins screen. 2. Activate the plugin through the `Plugins` screen in WordPress. 3. Go to `Media > imagIn – WebP & AVIF Converter`. 4. Choose WebP or AVIF as the output format. 5. Choose how original files should be handled after conversion. 6. Keep `Update page image references` enabled if converted images should replace matching JPG/PNG URLs in pages and builder data. 7. Set the image quality values. 8. Upload a JPG, JPEG, or PNG image to test automatic conversion. ## FAQ ### Does this plugin require a cloud account? No. All conversion happens locally on your WordPress server. ### Does imagIn send images to an external API? No. The plugin does not send image files, site data, or usage data to an external API or cloud service. ### What image formats can be converted? JPG, JPEG, and PNG images can be converted during upload. Existing JPG, JPEG, and PNG media files can be converted individually, selected in the Media Library for bulk conversion, or processed in batches from the imagIn settings page. ### What output formats are supported? The plugin supports WebP and AVIF when your server image library supports those formats. ### Why is WebP or AVIF unavailable on my server? WebP and AVIF support depends on the GD or Imagick configuration installed on your hosting server. If a format is unavailable, contact your hosting provider and ask whether the required image library support can be enabled. ### Why does conversion fail for a large image? Large images need much more server memory after they are opened for processing than their uploaded file size suggests. imagIn checks the image dimensions before conversion on GD-based servers and explains when the available PHP memory is not enough. Try a smaller image, increase the PHP memory limit, or ask your hosting provider to enable Imagick. ### Will the plugin delete my original image? Only if you choose `Replace original after successful conversion`. You can also keep the original file or move it to a backup folder. ### Can I convert existing images? Yes. Convert one image from its attachment details, select multiple JPG/PNG items and choose `Convert selected`, or use the bulk conversion control on the imagIn settings page. ### Will bulk conversion show its result? Yes. Bulk conversion runs in small batches and shows its progress. When the process finishes, imagIn reports how many images were converted successfully and how many need attention. Page and builder reference updates run in short follow-up requests so the conversion screen does not wait on a long database operation. ### Will my Elementor or page builder images be updated automatically? Yes. When `Update page image references` is enabled, imagIn updates matching JPG, JPEG, and PNG URLs in page content and post metadata after a successful conversion. This covers common Elementor data and other builders that store image URLs in WordPress content or metadata. In Keep mode, URL-based references can use the converted file while the original attachment ID and its WordPress metadata remain unchanged; Replace and Backup modes update the attachment metadata to the converted asset. ### Does this plugin use shell commands? No. The plugin does not use shell command execution. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “imagIn – WebP & AVIF Converter” is open source software.
