详情介绍:
Designed2Use Convert to WebP/AVIF is a privacy-first image optimizer with one promise the
big-name plugins can't make: your images never leave your server, and every conversion
can be undone.
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.
- 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.
- 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.
安装:
- Upload the
designed2use-convert-to-webpfolder to/wp-content/plugins/, or install through Plugins → Add New. - Activate the plugin through the Plugins screen.
- Go to Settings → Convert to WebP/AVIF, choose your output format, quality, and maximum edge (sensible defaults are set for you).
- Upload an image as usual — it's stored in the modern format automatically.
- To convert your existing library, open Media → Convert Existing and click Convert existing images.

常见问题:
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) — changequality,max_edge, ormime+extfor a single image. Receives$optsand the source file path.d2ucw_before_save(action) — runs after rotation and resizing, just before saving. Receives theWP_Image_Editor, the source path, the output path and the output mime type.
更新日志:
1.0.2
- Fix: portrait photos taken with a phone camera (e.g. the "Take photo" upload option) are no longer saved sideways. 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_argsandd2ucw_before_savefor customising conversion without editing plugin files.
- 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.
- 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. No external services.
