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. ## Screenshots [⌊Dashboard overview with totals for converted, pending, failed, and storage saved⌉⌊ Dashboard overview with totals for converted, pending, failed, and storage saved⌉[ Dashboard overview with totals for converted, pending, failed, and storage saved [⌊Bulk Convert screen showing progress and the image status table⌉⌊Bulk Convert screen showing progress and the image status table⌉[ Bulk Convert screen showing progress and the image status table [⌊Settings screen with conversion engine and delivery controls⌉⌊Settings screen with conversion engine and delivery controls⌉[ Settings screen with conversion engine and delivery controls [⌊Media Library integration with per-image convert action⌉⌊Media Library integration with per-image convert action⌉[ Media Library integration with per-image convert action [⌊Media Library integration with per-image restore action⌉⌊Media Library integration with per-image restore action⌉[ Media Library integration with per-image restore action ## Installation #### WordPress Admin Method 1.
