原文外掛簡介
Convert JPEG, PNG & GIF to WebP and bulk-optimize your Media Library entirely on your own server. No external services. No data sent. No quotas.
🚀 Local-First WebP Conversion For WordPress
SPINX Digital Image Converter generates lightweight WebP versions of your JPEG, PNG, and GIF uploads — including every WordPress-generated thumbnail size — so your pages load faster and your images stay lighter.
Unlike cloud-based optimizers, all processing happens on your own server using PHP’s GD or ImageMagick extension. Nothing is uploaded to a third party, no account is required, and there are no monthly limits or quotas. Your images never leave your hosting environment.
It’s built for site owners who want faster image delivery, a safe and reversible workflow, and a clear, honest view of exactly what was converted, skipped, restored, or failed — all from a single dashboard.
✨ Why Choose SPINX Digital Image Converter?
100% Local Processing — Images are converted on your server with GD or ImageMagick. No external API calls, ever.
Complete Privacy — No user data is collected or transmitted. No third-party libraries bundled.
Server Limit — Convert unlimited images, subject to your server’s available resources and processing capacity.
Fully Reversible — Restore originals and remove generated WebP files at any time, per image or in bulk.
Full Transparency — A real-time dashboard tracks converted, pending, failed, and storage-saved totals.
🖼️ Features at a Glance
Automatic Conversion on Upload — New JPEG, PNG, and GIF uploads are converted to WebP automatically. No manual steps, no forgotten images.
Bulk Conversion for Existing Media — Optimize your entire Media Library in batches. The plugin prepares the image list, processes it in manageable chunks, and updates progress live in the admin UI — ideal for large libraries.
Thumbnail Conversion Included — Every WordPress-generated image size is converted alongside the original attachment, so all served variants benefit from WebP.
Choice of Conversion Engine — Use GD or ImageMagick, with automatic detection based on what’s available on your host and your selected settings.
Optimized WebP Quality (Fixed 75%) — The plugin converts every image at a balanced, fixed 75% WebP quality for an ideal size-to-fidelity trade-off.
Media Library Integration — Convert or restore any individual image directly from Media Library row actions and attachment-level controls.
One-Click Restore — Switch delivery back to your original media files and remove generated WebP files whenever you need to.
REST API Access — Built-in REST endpoints for stats, health checks, logs, settings, exports, and per-image actions — all protected with nonce and capability checks.
📊 Know Exactly What’s Happening
Most optimization tools hide the details. SPINX Digital Image Converter gives you a dedicated dashboard with running totals for converted, pending, failed, and storage saved, plus a status table during bulk runs. You always know what’s been processed, what’s left, and how much space you’ve reclaimed.
🔒 Privacy & External Services
This plugin does not contact any external servers. All image processing happens on your own server using PHP’s GD or ImageMagick extension. No third-party libraries are bundled, and no user data is collected or transmitted. What runs on your site stays on your site.
💡 Best For
Blogs, marketing sites, portfolios, and eCommerce stores that want fast, local WebP generation.
Site owners who need bulk conversion without relying on third-party optimization services.
Privacy-conscious teams who require all media processing to stay on their own infrastructure.
Anyone who wants clear visibility into image status and real storage savings.

Dashboard & Bulk Convert
Clickable Stat Cards — click any statistic (Total, Convertible, Converted, Pending, Failed, Already WebP, Unsupported) to open a dedicated, filtered Images screen.
Images Screen — browse images by status with pagination, and convert, restore, or retry any image individually, with the exact error shown for failed conversions.
Image Comparison — open a before/after slider for any converted image, with original size, WebP size, savings percentage, and dimensions.

Smart Action Buttons — bulk actions disable themselves automatically when there is nothing left to convert or restore.

Secure SVG Uploads — allow SVG files in the Media Library, restricted to the user roles you choose.
