Bulk Image to WebP Converter
WordPress.org-ready local-first PNG/JPEG to WebP converter with unlimited manual Free conversions and safe repeatable batches.
Install
This is the repository archive. It installs, but the folder name will carry the branch suffix and updates will not flow.
Install straight from GitHub with WP-CLI:
wp plugin install https://github.com/lavenex/bulk-image-to-webp-converter-free/archive/refs/heads/main.zipThis directory is the complete WordPress.org Free plugin. It converts manually selected PNG/JPG/JPEG images to WebP locally in the administrator's browser and saves successful results as new Media Library attachments.
The Free package is fully functional: unlimited manual conversions, repeatable 25-image safety batches, up to 10 MB per image subject to host limits, full quality control, Media Library selection and saving, refresh-safe queue controls, progress, history, diagnostics, and original-file preservation.
No license system, entitlement check, premium implementation, daily quota, trial, or locked feature code is included. Any separately distributed commercial add-on is a different GPL-compatible plugin hosted outside WordPress.org.
