原文外掛簡介
Flex Image Optimizer is part of the FLEX plugin suite from FLEX LLC (https://flexible.am/). 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.
