Most popular optimizers upload your images to a third-party cloud service to do the work — counting against monthly quotas and handing your media to someone else’s servers. This plugin does everything **locally**, using WordPress’s own image editor( Imagick, falling back to GD). No accounts, no API keys, no external requests. #### Why it’s different * **100% local & private** — no cloud service, no telemetry, no phone-home. Every image is processed on your own site. * **Fully reversible** — bulk conversion (and uploads made with “Keep original file” on) keep your original file on disk and record a restore manifest, so you can put any image (or all of them) back with one click. Uploads that replace the original can’t be undone. * **WebP _or_ AVIF** — choose the modern format you want. AVIF (newer, smaller) is offered automatically when your server supports it, with a safe fall back to WebP. * **See your savings** — a built-in dashboard shows how much disk space you’ve saved, all calculated on-site. #### What it does * **Converts on upload** — JPG/JPEG and PNG uploads become WebP or AVIF automatically, and because the conversion happens before WordPress builds its sub-sizes, every thumbnail size is generated in the new format too. * **Converts existing media** — a batch tool under **Media Convert Existing** processes your library a few images at a time with a live progress bar (no timeouts). * **Convert & restore from the Media Library** — convert or restore a single image right from its details (both list and grid view), or select several and use the Media-list bulk actions; roll back the whole library from the Tools page. * **Resizes oversized images** — anything larger than your chosen longest-edge limit is scaled down (aspect ratio preserved); smaller images are never enlarged. * **Never breaks an upload** — if anything goes wrong, or the server can’t write the format, the original file is kept and the upload proceeds normally. #### Settings Under **Settings Convert to WebP/AVIF**: * **Enable conversion** — master on/off switch for upload-time conversion. * **Output format** — WebP (broad support) or AVIF (smaller, when available). * **Quality** — 1–100 (default 80). Lower means smaller files. * **Max longest edge (px)** — default 1600. Set 0 to convert without resizing. This replaces WordPress’s own 2560px “big image” scaling for converted images, so they are never resized twice or renamed with a “-scaled” suffix. * **Keep original file** — affects new uploads only; off by default (the original is replaced). Turn on to keep both — and only then can an upload be restored later. * **Convert these formats** — JPG/JPEG and PNG, plus **WebP / AVIF (resize only, format kept) : already-modern uploads keep their format and filename and are only resized to the max longest edge. With Keep original file on, the untouched upload is saved alongside as `name-original.webp` (or `.avif`) so it can be restored. #### Converting and restoring existing images Go to **Media Convert Existing**. The page shows how many images still need converting, how many can be restored, and your running savings total. Conversions run in safe batches. Because bulk conversion **always keeps the original file on disk**, the change is never destructive: use **Restore all to originals** on the Tools page, or the ** Restore original** row action on any converted item in the Media list (single images, or several at once via the Media-list bulk actions), to delete the converted files and put the attachment back exactly as it was. Uploads converted with **Keep original file** turned on are restorable the same way; uploads that replaced their original cannot be undone. #### Privacy This plugin contacts **no external server**, collects no data, and adds no tracking. WebP and AVIF are written by your own server’s image library. Everything happens on your site. ## Screenshots [⌊Settings — output format (WebP/AVIF), quality, maximum edge, and format options.⌉⌊ Settings — output format (WebP/AVIF), quality, maximum edge, and format options.⌉[ Settings — output format (WebP/AVIF), quality, maximum edge, and format options.

Upload the `designed2use-convert-to-webp` folder to `/wp-content/plugins/`, or install through **Plugins Add New**. 2. Activate the plugin through the **Plugins** screen. 3. Go to **Settings Convert to WebP/AVIF**, choose your output format, quality, and maximum edge (sensible defaults are set for you). 4. Upload an image as usual — it’s stored in the modern format automatically. 5. To convert your existing library, open **Media Convert Existing** and click ** Convert existing images**. ## FAQ ### Does it send my images to a cloud service? No. Unlike many optimizers, this plugin does all conversion on your own server using WordPress’s built-in image editor. There are no external requests, accounts, or quotas. ### Can I undo a conversion? Yes — as long as the original is still on disk. Bulk conversion always keeps originals, and uploads keep theirs when **Keep original file** is enabled. Use **Restore all to originals** on the Tools page, the **Restore original** row action on any converted image, or the Media-list bulk action for several at once. Restore deletes the converted files and puts the attachment back to its original file, mime type, and thumbnails. Uploads that replaced their original (the default) cannot be undone. ### WebP or AVIF — which should I choose? WebP has the broadest browser and host support and is the default. AVIF produces smaller files and is offered when your server’s image library can write it; if you select AVIF on a server that can’t, the plugin safely falls back to WebP. ### Does it convert images already in my Media Library? Yes — that’s what **Media Convert Existing** is for. It processes JPG/PNG attachments in batches with a progress bar and updates the savings dashboard as it goes. ### Will my originals be deleted? Bulk conversion never deletes originals — that’s what makes restore possible. For new uploads, the original is replaced by default; turn on **Keep original file** to keep both, which is also what makes an upload restorable later. ### Does it work on shared hosting? Yes, as long as the server’s image library can write the chosen format — the Imagick PHP extension, or GD with WebP/AVIF support. If it can’t, the plugin shows a notice and leaves your images untouched. ### Can developers customise the conversion? Yes. Both upload and bulk conversion go through the same two hooks: * `d2ucw_convert_args` (filter) — change `quality`, `max_edge`, or `mime` + `ext` for a single image. Receives `$opts` and the source file path. * `d2ucw_before_save` (action) — runs after rotation and resizing, just before saving. Receives the `WP_Image_Editor`, the source path, the output path and the output mime type. ## Reviews ![](https://secure.gravatar.com/avatar/c13402ced9a820a6b71096bfa21739d58bd03f85d3c367e30689ec7fc4437830? s=60&d=retro&r=g) ### 󠀁[Excellent, does exactly what is needed](https://wordpress.org/support/topic/excellent-does-exactly-what-is-needed/)󠁿 [unostar](https://profiles.wordpress.org/unostar/) Gwynngala 14, 2026 This is a perfect professional solution for developers: this plugin does exactly what is needed.

The photo’s EXIF orientation is now applied before converting to WebP/AVIF. * Fix: with “Max longest edge” set to 0 or above 2560px, converted images were resized a second time by WordPress’s “big image” scaling and renamed to “-scaled”. The plugin’s max-edge setting now applies on its own, for uploads and bulk conversion. * New: WebP and AVIF uploads are resized to the max longest edge (format and filename kept) instead of being scaled by WordPress to 2560px with a “-scaled” suffix. Can be turned off under “Convert these formats”. * New: developer hooks `d2ucw_convert_args` and `d2ucw_before_save` for customising conversion without editing plugin files. #### 1.0.1 * WordPress 7.1 compatibility: while upload conversion is enabled, WordPress 7.1’ s in-browser image processing is switched off, so each upload is resized and converted once, on your server, exactly as on earlier WordPress versions (instead of being compressed in the browser and then again by the plugin). * Tested up to WordPress 7.1. #### 1.0.0 * Initial release: private, on-server conversion of uploads and existing media to WebP or AVIF; resize-to-max-edge; convert and restore from the Media Library( row actions and bulk actions); one-click restore of a single image or the whole library — including uploads kept with “Keep original file”; and a local savings dashboard.
