wpcustomca Frontend Upload Watermark can automatically apply a configurable logo and/or text watermark to images uploaded from the website frontend.
The plugin is frontend-focused and includes a built-in upload shortcode for authorized users:
- Frontend image uploads can be watermarked automatically.
- Add [media_watermark_upload] to any page/post to show a frontend image upload form.
- Shortcode uploads are saved to the WordPress Media Library and watermarked automatically.
- WordPress Admin > Media Library / Add New uploads are skipped.
- Enable/disable frontend watermarking from Settings > Frontend Upload Watermark.
- Configure logo, text, position, opacity, size, margin, and minimum image dimensions.
- Supports JPEG, PNG, and WebP when supported by the server's GD library.
Important: Watermarking modifies the uploaded image files. Keep backups when originals may be required.
