Silverstripe Image Optimiser Report

CMS report and tooling that trials WebP conversions for PNG assets, surfaces worthwhile candidates, and lets editors replace originals in place.

Installation

composer require akqa/silverstripe-image-optimiser-report

Run dev/build after installing so the WebP assessment columns are added to File.

Usage

1. Queue assessment of unassessed PNG files:

   sake tasks:WebpConversionTask --queue

   Or assess a small batch inline:

   sake tasks:WebpConversionTask --assess --limit=10

2. Open Reports → Image conversion report in the CMS.

3. Use Queue assessment to process files in the background, or filter to Not yet assessed and assess files one at a time.

4. Preview PNG vs WebP, then use Replace with WebP on candidates you want to swap. The File record ID is preserved so existing relations follow.
