Private, reversible image optimization — WebP & AVIF, all on your own server

Designed2Use Convert to WebP/AVIF shrinks your images by converting them to modern formats — without ever uploading them to a third-party service, and without ever making a change you can’t undo. New uploads are handled automatically; your existing Media Library converts in safe batches; and conversions can be undone with one click — a single image, right from the Media Library, or your whole library at once.

Built properly: the two things other optimizers get wrong

1. They send your images to the cloud. Most popular image optimizers upload your media to their servers to do the compression — which means monthly quotas, a dependency on someone else’s uptime, and your images leaving your site. This plugin does everything locally, using WordPress’s own image editor (Imagick, falling back to GD). No accounts, no API keys, no external requests. Ever.

2. They make conversion a one-way door. Bulk-converting a media library is nerve-wracking when there’s no undo. Here, bulk conversion always keeps your original file on disk — and uploads can too, with one setting — recording exactly what changed, so you can restore a single image (straight from the Media Library) or your entire library and get back the original JPG/PNG, mime type, and thumbnails precisely as they were.

That’s the whole pitch: the optimizer that respects your privacy and never traps you.

WebP or AVIF — your choice

Pick the modern format you want. WebP has the broadest browser and host support and is the default. AVIF is newer and produces even smaller files — it’s offered automatically when your server can write it, with a safe fall back to WebP when it can’t. Either way, the conversion happens before WordPress builds its thumbnail sizes, so every size is generated in the modern format, not just the full-size image.

See exactly what you’re saving

A built-in dashboard shows how many images you’ve converted and how much disk space you’ve saved — original size, converted size, and the percentage reduction — all calculated on your own site. Real numbers, no external analytics.

Features

• Automatic conversion on upload — JPG/JPEG and PNG become WebP or AVIF with no buttons to press.
• Batch converter for existing media — a Tools page with a live progress bar and per-image log, processing in safe batches that never time out.
• Convert & restore from the Media Library — convert or restore a single image right from its details in both list and grid view, or act on several at once with the list-view bulk actions; roll back your whole library from the Tools page.
• Reversible uploads too — turn on Keep original file and even automatic upload conversions can be restored later (uploads that replace the original can’t be undone).
• Savings dashboard — total space saved, computed locally.
• Smart resizing — scale down to a maximum longest edge; smaller images are converted without being enlarged.
• Modern thumbnails everywhere — every registered image size is regenerated in the new format.
• 100% local & self-contained — no external services, no API keys, no bundled libraries.

Privacy & security

• No phone-home. The plugin contacts no external server, collects no data, and adds no tracking. Every image is processed on your own site.
• All admin output is escaped; batch and restore actions are protected by nonces and capability checks.
• Clean against the official WordPress Plugin Check, following the WordPress Coding Standards.

Requirements

• WordPress 6.0 or later
• PHP 7.4 or later
• A server image library that can write WebP (and, for AVIF, AVIF support) — the Imagick PHP extension, or GD compiled with the relevant format support. If it can’t, the plugin shows a notice and leaves your images untouched.

Getting started

1. Install and activate the plugin (search “Designed2Use Convert to WebP/AVIF” in Plugins → Add New, or download from WordPress.org).
2. Go to Settings → Convert to WebP/AVIF, choose WebP or AVIF, and set your quality and maximum edge (sensible defaults are set for you).
3. Upload an image as usual — it’s stored in the modern format automatically.
4. To convert your back catalogue, open Media → Convert Existing and click Convert existing images. Changed your mind? Restore all to originals is right there — or convert/restore individual images straight from the Media Library.
