详情介绍:
Perxel Image Optimizer converts your WordPress media library to WebP locally,
on your own server, and serves it - entirely from an admin page, built for shared
hosting.
- No third party. Conversion runs in PHP via WP_Image_Editor (GD/Imagick). Nothing is uploaded to a CDN or an external optimization service, and there is no API key, account or paid tier. Your images never leave your host.
- Free. The whole plugin, no upsell.
- Runs in the background. A light scan estimates the work, then a background job (Action Scheduler) converts the library newest-to-oldest, one calendar month at a time. Pause, resume, cancel, close the tab - progress is durable. Optional email report when a run finishes.
- Or run it Fast. An opt-in mode that drives the conversion from the open admin tab, so the server works continuously - much quicker on shared hosting with no cron. It throttles itself if the host pushes back, and stopping never loses work.
- Your JPEG and PNG files stay.
foo.jpggets afoo.jpg.webpsibling; the conversion never modifies the source file. - Image size limit. New uploads are scaled down to a maximum size (1920 px by default, adjustable), and the unused full-size original WordPress keeps beside a scaled upload is deleted to save disk space (can be turned off). "Shrink existing images" does the same once for images uploaded before.
- Serving through a managed
.htaccessblock on Apache/LiteSpeed, with an<img>to<picture>fallback on nginx or when.htaccessis not writable. - Per-attachment Convert / Reconvert / Remove buttons in the Media library.
- New uploads are converted automatically, shortly after upload.
- WP-CLI commands (
wp perxel-image) for running it over SSH.
安装:
- Upload the
perxel-image-optimizerfolder to/wp-content/plugins/. - Activate the plugin through the Plugins screen.
- Go to Media > Optimization.

常见问题:
Does it modify my original images?
The WebP conversion never does: every converted file is a new .webp sibling
next to the original. The image size limit does, by design: a new upload
bigger than the maximum (1920 px by default) is scaled down, and the full-size
original WordPress keeps beside the scaled copy is deleted. Set the maximum to
0 for no limit, or turn off "Delete originals of scaled uploads" to keep them.
"Shrink existing images" (or wp perxel-image cleanup) changes images already
uploaded only when you run it, and cannot be undone.
Can I run it over SSH?
Yes, with WP-CLI: wp perxel-image status, wp perxel-image convert,
wp perxel-image cleanup --dry-run and wp perxel-image settings get|set.
What happens on nginx?
The .htaccess swap is Apache-only. On nginx the plugin rewrites <img> tags to
<picture> with a WebP source instead.
更新日志:
1.1.0
- New: image size limit. New uploads bigger than the maximum (1920 px by default, adjustable in Settings, 0 = no limit) are scaled down on their longest side.
- New: the full-size original WordPress keeps beside a scaled upload is deleted, to save disk space. On by default; turn off "Delete originals of scaled uploads" to keep them.
- New: "Shrink existing images" in Settings deletes the kept originals of images uploaded before and scales full-size images over the maximum down, in place, so links keep working. Their WebP copies are redone automatically.
- Fix: deleting an image now deletes its WebP copies too (they were left on disk).
- New: WP-CLI commands:
wp perxel-image status,convert,cleanup(with--dry-run) andsettings.
- Housekeeping only, no behaviour change. Plugin URI now points to the product page on perxel.com instead of the GitHub repo.
- Tightened output-escaping suppressions in the admin views to per-file targeted ignores, addressing the plugin review's escaping feedback.
- Media Library scripts/styles now load only on the Media list and the single-attachment edit screen.
- First public release.
- Local WebP conversion via WP_Image_Editor - no CDN, no external service, free.
- Month-scoped bulk run with two drivers: a background run on Action Scheduler (pause, resume, cancel, durable progress, optional completion email) and an opt-in Fast mode where the browser tab drives the encode loop directly, for shared hosting with no working WP-Cron loopback. Fast mode self-pauses when the host throttles and resumes after an escalating cooldown; a live Gentle / Balanced / Turbo control sits on the running monitor.
- Closing the tab, Stop, or Cancel never reverts converted files - the run parks and resumes from where it left off.
- Per-attachment Convert / Reconvert / Remove buttons in the Media library, and automatic conversion of new uploads.
- Serving via a managed
.htaccessblock on Apache/LiteSpeed, with an<img>to<picture>fallback elsewhere. - Two admin screens under Media > Optimization - Optimization (prepare + live monitor) and Settings - in a shared sidebar layout, server-rendered.
