Available Options

Automatic Conversion

  • Description: enables/disables automatic conversion of uploaded images to WebP or AVIF.
  • Behavior:
    • When enabled (green toggle), all new images are converted automatically.
    • When disabled, images remain in their original formats (JPEG, PNG, GIF).

Conversion Engine

  • Options: Server or Browser.
  • Server: conversion happens on the server; supports both new and existing images.
  • Browser: reduces server load but only works on browsers supporting conversion (Chrome, Firefox, Edge, Opera) and only for new uploads.

Conversion Format

  • Choice: WebP or AVIF.
  • Note: only JPEG, PNG, or GIF images are converted.

WEBP Quality / AVIF Quality

  • Levels: Lossy, Glossy, Lossless.
  • Custom: adjusts quality/compression (0–100). Lower values reduce file size but also image quality.

Remove Metadata

  • Description: automatically removes unnecessary metadata (EXIF, geolocation, etc.).
  • Requirement: requires Imagick.
  • Note: useful for reducing file size, but important photographic details may be lost.

Delete Original Images

  • Description: automatically deletes original images after conversion.
  • Warning: irreversible action. Always back up your site and files first.
  • Note: keeping originals increases disk usage but allows regenerating new variants if needed.

Save Settings

  • Function: saves all changes.
  • Note: applies only to images uploaded after saving.
