Full Changelog: v1.2.4...v1.3.0

WebP Image Optimizer v1.2.4

WebP Image Optimizer v1.2.4

A comprehensive update to the WebP Image Optimizer plugin for WordPress, focused on reliability, efficiency, and user experience.

Description

This release introduces robust file management and improved image conversion logic. When images are deleted from the Media Library, all related files—including originals, WebP versions, and intermediate sizes—are now properly removed from the file system. PNG images are converted using lossy compression by default, with an option for lossless conversion; note that lossless mode ignores the quality setting. SVG has been removed from the list of allowed image types, as it cannot be converted to WebP. All admin settings, including checkboxes, now save and reflect their state accurately. The conversion process is more robust, always stripping metadata, reducing color palettes for lossy PNGs, and providing debug logging for file sizes before and after conversion.

This update ensures more efficient storage usage, better compatibility, and a smoother experience for site administrators.

Changelog

• Improved deletion: When deleting an image from the Media Library, all related files (original, WebP, and intermediate sizes) are now properly deleted from the file system.
• Lossy/lossless PNG handling: PNGs are now lossy by default unless lossless is explicitly selected. Lossless mode ignores the quality setting, as expected.
• Removed SVG from Allowed Image Types (SVG cannot be converted to WebP).
• Fixed admin settings: All checkboxes now save and reflect their state correctly, including 'Set Alt Text'.
• Improved conversion robustness: Always strips metadata, reduces color palette for lossy PNGs, and adds debug logging for file sizes before/after conversion.
