原文外掛簡介
Wiwercy Web Image Converter optimizes WordPress images by converting supported source formats to AVIF or WebP directly on your server.
The plugin is designed for both new uploads and existing Media Library attachments. Conversion runs on your server with Imagick or GD; images are not sent to a remote optimizer. Its Safe Family Migration workflow converts the managed image family, preserves the existing size set 1:1, and verifies attachment metadata and matching post references before removing replaced source files. Failures before that point trigger recovery of the original attachment state and exact post contents. If recovery cannot be verified, both original and replacement files are retained and the problem is reported.
Main features
AVIF or WebP output with quality control from 10 to 100.
JPEG/JPG input enabled by default.
Optional PNG, HEIC/HEIF, BMP, TIFF/TIF source formats.
Automatic backend selection: Imagick, then GD.
Backend diagnostics show which enabled inputs can be read and whether AVIF/WebP can be written.
Optional metadata stripping and JPEG orientation correction.
“Keep original if not smaller” safeguard.
Safe Media Library conversion that preserves the current WordPress image family 1:1.
Existing matching image URLs in posts and pages are updated after successful attachment migration.
Conversion history, storage overview and quality preview.
No paid tier and no feature locking.
Translation-ready admin interface. WordPress.org delivers community translations through translate.wordpress.org.
Before processing an existing Media Library, create a current backup of the WordPress database and uploads directory.
Privacy
Wiwercy Web Image Converter processes images locally on the WordPress server.
The plugin does not send images to an external conversion service, does not collect telemetry or analytics, and does not transmit site usage data to Wiwercy.
The plugin does not load third-party JavaScript, CSS or tracking resources. The optional donation link opens PayPal only when the administrator chooses to click it.
Plugin updates for the WordPress.org distribution are handled by the standard WordPress.org update system.
