تفصیل
IndexLane Safe WebP Queue converts JPEG and PNG media attachments and their generated image sizes to sibling .webp files from inside wp-admin.
The plugin checks local server support, estimates memory risk, preserves original files, skips unsafe files, and reports which images converted, skipped, or failed.
It is built for cautious local conversion, not cloud optimization or automatic original-file replacement.

What it does:
- Scans JPEG and PNG attachments in the Media Library.
- Checks GD and Imagick WebP support.
- Estimates memory risk before conversion.
- Converts selected original images and generated attachment sizes through a persistent small-batch queue.
- Keeps conversion progress when the plugin page is closed and uses WP-Cron when site traffic permits.
- Keeps original files.
- Reports sibling WebP files not owned by this plugin as conflicts and leaves them unchanged.
- Skips files that are too large, unsupported, missing, or likely unsafe for the current server.
- Exports the visible report as CSV.
- Deletes WebP files generated by this plugin when explicitly requested.
- Optionally uses generated WebP files in normal WordPress image output where a matching generated file exists.
- Can optionally queue WebP generation for new uploads after WordPress finishes creating attachment sizes.
- Reconciles plugin-owned WebP files when attachment sizes change or an attachment is deleted.
- Detects changed source files and changed quality settings before regenerating output.
Limits:
- Does not rewrite post content.
- Does not replace attachment URLs.
- Does not delete original images.
- Does not convert GIF, SVG, AVIF, or existing WebP files.

عمومی سوالات
-
Does this replace my JPEG or PNG files?
-
No. Original files are preserved. The plugin creates sibling
.webpfiles beside original and generated attachment image files. -
Will my frontend automatically serve WebP after conversion?
-
No. Frontend serving is off by default. When enabled, the plugin uses generated WebP files in normal WordPress image output where a matching generated file exists. It does not rewrite post content, attachment URLs, or database content.
-
Does this convert new uploads automatically?
-
Not by default. Existing media can be scanned and converted from Tools -> IndexLane Safe WebP Queue. Automatic WebP generation for new uploads can be enabled in settings. New uploads are queued so conversion does not extend the upload request; WP-Cron processes them when site traffic permits.
-
Does it use a cloud service?
-
No. Conversion runs locally through WordPress image editors, GD, or Imagick when WebP writing support is available.
-
Why are large images skipped?
-
Image conversion memory use depends on decoded pixels, not just compressed file size. The plugin estimates decoded memory as width x height x 5 and skips files that look risky for the current PHP memory limit.
