安裝方式

常見問題集

What image formats are supported?

JPEG, PNG, GIF, and WebP. You can optionally convert output to WebP regardless of the source format.

Can I restore the original image after watermarking?

Yes. When backup is enabled, originals are saved before watermarking. Restore from the admin UI, attachment edit screen, or WP-CLI.

Can I watermark existing images?

Yes. Use the batch processor in the admin UI or run wp watermark batch from the command line.

Does it work with WP-CLI?

Yes. Commands include wp watermark apply, wp watermark batch, wp watermark remove, wp watermark status, and wp watermark templates.

What happens when I delete the plugin?

All plugin options, post meta, watermark templates, cron events, and the backup directory are removed on uninstall.
