OrigiSafe — Advanced Image Optimizer (WebP) — Keep Originals Safe

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

    • 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.
  2. Move originals

    • The original JPG/PNG files are moved to:
      • wp-content/uploads/_originals/...
    • The folder structure mirrors your uploads structure.
  3. Update WordPress to serve WebP

    • Attachment “file” + metadata are updated so WordPress serves .webp as the attachment file.
    • Attachment mime type is updated to image/webp.
  4. Optional: Replace old URLs everywhere

    • 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 <root>/_originals/ when the same file exists at <root>/ 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 <picture> 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.
