It keeps image work on your WordPress server. There is no compression API, no CDN account, and no call home. * Bulk regenerate all thumbnail sizes, or only missing sizes * Generate WebP (and optional AVIF) copies next to JPEG/PNG files * Serve modern formats with a picture tag so JPEG/PNG remains the fallback * Allow SVG uploads with sanitization (scripts and unsafe markup removed) * Resize oversized originals, set JPEG/WebP quality, and strip GPS/EXIF * Skip unused registered sizes (including 1536×1536 / 2048×2048) * Media library column, row actions, bulk actions (up to 20), and WP-CLI Admin CSS and JavaScript ship with the plugin. No remote stylesheets, no telemetry. #### Privacy Flex Image Optimizer does not send images or metadata to FLEX or any third-party service. Processing uses the WordPress image editor (Imagick or GD) on this site. Optional EXIF stripping is done on the server. SVG sanitization runs on upload before the file is stored. #### Limitations * WebP and AVIF require PHP/GD or Imagick built with those formats. * Animated GIF is not converted. * Picture-tag rewriting wraps `img` tags. CSS that requires `img` to be a direct child of another element may need a small adjustment. * SVG is treated like HTML: only trust roles you allow to upload it. * This is not a CDN, lazy-load extra, or offsite backup plugin. ## Ảnh màn hình [⌊Tools — regenerate thumbnails and generate WebP/AVIF⌉⌊Tools — regenerate thumbnails and generate WebP/AVIF⌉[ Tools — regenerate thumbnails and generate WebP/AVIF [⌊Settings — compression, SVG, and sizes⌉⌊Settings — compression, SVG, and sizes⌉[ Settings — compression, SVG, and sizes [⌊Usage — in-plugin guide⌉⌊Usage — in-plugin guide⌉[ Usage — in-plugin guide ## Cài đặt 1. Upload the `flex-image-optimizer` folder to `/wp-content/plugins/`, or install the zip via **Plugins Add New Upload Plugin**. 2. Activate **Flex Image Optimizer**. 3. Open **Flex Images Settings** and review WebP, SVG, and quality. 4. Open **Tools** to generate WebP for the existing library or regenerate thumbnails. ## Hỏi đáp ### Where are WebP files stored? Next to the original, with an extra extension: `photo.jpg.webp`. Thumbnails follow the same pattern. Deleting the media item removes those copies. Uninstalling the plugin does not. ### Will visitors without WebP support see a broken image? No. The original JPEG or PNG stays in the `img` tag. Supporting browsers pick WebP or AVIF from the picture sources. ### Is SVG safe? The plugin strips scripts, event handlers, foreignObject, and external URLs. That is not a guarantee against every XML trick. Keep SVG limited to administrators unless you trust the other roles. ### Can I regenerate one image? Yes. In the media library, hover the row and use **Regenerate thumbnails** or ** Generate WebP**. Bulk actions handle up to 20 selected items. ### What happens when I uninstall? Plugin settings are removed. Uploaded images and generated WebP/AVIF files stay in the uploads directory. ## Đánh giá Không có đánh giá nào cho plugin này. ## Người đóng góp & Lập trình viên “Flex Image Optimizer” là mã nguồn mở.
