## Description
Keep Originals Safe, convert JPEG/PNG images to WebP and makes WebP the canonical
file. WP returns `.webp` URLs, Keeping originals safely archived.
### How it works (high level)
1. **Convert**
2. * For a JPG/PNG attachment, the plugin generates a WebP for the full image and
all WordPress-generated sizes.
* Conversion is done through WordPress’ image editor system (**WP_Image_Editor**),
meaning it uses **GD** or **Imagick** (whichever your server supports) with
WebP support enabled.
3. **Move originals**
4. * The original JPG/PNG files are moved to:
- `wp-content/uploads/_originals/...`
* The folder structure mirrors your uploads structure.
5. **Update WordPress to serve WebP**
6. * Attachment “file” + metadata are updated so WordPress serves `.webp` as the
attachment file.
* Attachment mime type is updated to `image/webp`.
7. **Optional: Replace old URLs everywhere**
8. * If enabled, the plugin can replace old `.jpg/.png` URLs across:
- post content
- postmeta
* Replacement is **serialized-safe** (does not break serialized arrays).
### Background jobs (keeps running after page reload)
Conversion/repair/sweep jobs are designed to run in the background. They keep ticking
even if you refresh the page or close the tab.
The plugin uses multiple loopback methods (admin-post / REST / public tick fallback)
so it can keep working even on restrictive hosting setups.
### Log + “it looks frozen” note
A rolling “terminal style” log is written to:
– `wp-content/uploads/hsbc-webp-only/
logs/webp-only.log`
If the log appears to freeze in the admin page:
– click **Refresh Log**, or – refresh
the page
The job may still be running server-side; refreshing the log/page usually catches
up.
### Usage
Go to **Media WebP Only**.
### Settings
* **Quality**
- WebP quality for conversion (0–100).
* **Batch size**
- How many items to process per tick. Smaller batches reduce server load.
* **Replace old .jpg/.png URLs across content + postmeta (serialized-safe)**
- Recommended if your site content contains hard-coded image URLs.
* **Sweep Include / Exclude**
- Used by the Sweep tools to control which folders are scanned.
### Conversion Jobs (buttons)
**Start Bulk Convert**
– Converts Media Library attachments (JPG/PNG) in batches.–
Moves originals to `uploads/_originals/`. – Updates attachment metadata so WordPress
serves `.webp`. – Optional URL replacement (content + postmeta).
**Start Repair/Cleanup**
– Repairs inconsistencies if something was partially converted
or moved. – Useful after restores/migrations or if some attachments have mismatched
metadata. – Optional URL replacement.
**Start Folder Sweep**
– Scans the filesystem for eligible images (based on your
Sweep Include/Exclude rules). – Designed for sites with additional image folders
beyond standard uploads. – Optional URL replacement.
**Stop Job**
– Stops the currently running job.
### Maintenance / Cleanup (buttons)
**Delete duplicate _originals**
– Deletes backup files in `uploads/_originals/`*
only when* an identical file already exists in `uploads/`. – This is a cleanup tool
for situations where originals were restored back into uploads and you no longer
need the archived duplicate.
**Delete duplicate _webp**
– Removes orphaned WebP cache files in: – `uploads/_webp/`–
Only deletes WebP files that no longer match anything in `uploads/` or `uploads/
_originals/`.
**Delete duplicate sweep _originals**
– Maintenance cleanup for **non-uploads**
roots (folders under `wp-content/`) that contain their own `_originals/` folders.–
It uses your **Sweep Include** list to find those roots. – Only deletes a file from`
/_originals/` when the same file exists at `/` AND the file size matches(
safe duplicate).
**Revert Everything**
– Restores original JPG/PNG files from `uploads/_originals/`
back into `uploads/`. – Reverts attachment metadata so WordPress serves the originals
again.
### Log controls
**Refresh Log**
– Pulls the latest log tail into the admin screen.
**Reset Log**
– Clears the log file.
### Requirements
* WordPress’ image editor must support WebP.
- **GD** with WebP support, or
- **Imagick** with WebP support
* If WebP conversion is not supported on your server, conversion/repair/sweep will
refuse to run (revert tools can still work).
## Installation
1. Upload the plugin folder to `/wp-content/plugins/`
2. Activate the plugin
3. Go to **Media WebP Only**
## FAQ
### Does this delete my originals?
No. Originals are moved into `wp-content/uploads/_originals/` and can be restored
with **Revert Everything**.
### Does this create “sidecar” WebP while keeping the JPG/PNG as the main file?
No. This plugin is designed to make WebP the canonical attachment file in WordPress(
while keeping originals archived).
### What does “Replace everywhere” do?
It replaces old `.jpg/.png` URLs in post content and postmeta. It is serialized-
safe to avoid breaking serialized values.
### Why do I see an `_webp` folder?
The plugin can reuse archived WebP files and also provides a cleanup tool that removes
orphaned WebP files that no longer match anything.
### What this plugin does NOT do
* It does not generate AVIF (WebP only).
* It does not add `` tags or do theme-level markup changes.
* It does not optimize already-WebP images.
* It does not rewrite external/CDN image URLs outside your WordPress database content/
postmeta.
