Bulk Image Resize<\/strong> Safe WebP Conversion<\/strong> Safe Replace Mode<\/strong> Safe Delete Mode<\/strong> Admin Statistics + Logs<\/strong> All warnings (missing files, unsupported types, editor errors) are logged and shown to the administrator.<\/p>\n\n Automatic Server Capability Detection<\/strong> Unsupported features are automatically disabled with an explanation.<\/p>\n\n Fully Internationalized (i18n)<\/strong> Only when both features are enabled: Yes. WebP attachments automatically inherit: If \u201cReplace old images\u201d is enabled, the plugin updates posts\/pages that contain the converted images. Yes. The plugin is optimized to handle large numbers of images, and includes safety checks, capability detection, and detailed logging.<\/p>\n\n<\/dd>\n\n<\/dl>\n\n\n Security & safety<\/strong>\n\u2013 Added strict sanitization for all numeric options. Stability & UX<\/strong>\n\u2013 Added detailed admin report with full statistics after processing. Compatibility<\/strong>\n\u2013 Improved i18n: translators comments added for all placeholder strings.
\n\u2022 Automatically resizes images to a maximum width\/height
\n\u2022 Maintains aspect ratio (no cropping, unless enabled)
\n\u2022 Skips small images to reduce unnecessary processing<\/p>\n\n

\nTo prevent content breakage, original images are deleted only when both conditions are met<\/strong>:\n1. Replace Old Images = enabled
\n2. Crop = disabled
\nIf delete was requested in unsafe configuration, the plugin logs a warning and ignores the deletion.<\/p>\n\n
\nAfter each run, the plugin displays a detailed summary:
\n\u2022 Images cropped
\n\u2022 Images converted to WebP
\n\u2022 Pages updated
\n\u2022 Originals deleted
\n\u2022 Total completed operations<\/p>\n\n

\n\u2022 WebP conversion<\/p>\n\n
\nAll dynamic strings include translator comments, following WordPress.org standards.<\/p>\n\n\n\n
