Plugin Description

IndexLane Safe WebP Queue converts JPEG and PNG media attachments and their generated image sizes to sibling .webp files from inside wp-admin.

The plugin checks local server support, estimates memory risk, preserves original files, skips unsafe files, and reports which images converted, skipped, or failed.

It is built for cautious local conversion, not cloud optimization or automatic original-file replacement.

What it does:

  • Scans JPEG and PNG attachments in the Media Library.
  • Checks GD and Imagick WebP support.
  • Estimates memory risk before conversion.
  • Converts selected original images and generated attachment sizes to sibling .webp files.
  • Keeps original files.
  • Reports sibling WebP files not owned by this plugin as conflicts and leaves them unchanged.
  • Skips files that are too large, unsupported, missing, or likely unsafe for the current server.
  • Exports the visible report as CSV.
  • Deletes WebP files generated by this plugin when explicitly requested.
  • Optionally uses generated WebP files in normal WordPress image output where a matching generated file exists.
  • Can optionally generate WebP files for new uploads after WordPress finishes creating attachment sizes.

Limits:

  • Does not rewrite post content.
  • Does not replace attachment URLs.
  • Does not delete original images.
  • Does not convert GIF, SVG, AVIF, or existing WebP files.
  • Does not crawl CSS, theme files, page builder fields, or hardcoded image URLs.
  • Does not call an external API or optimization service.
  • Frontend WebP serving is off by default and only affects normal WordPress image output when enabled.
  • New-upload conversion is off by default.
