Filigrane – Text & Logo Image Watermark, Originals Untouched

Filigrane is an image watermark plugin for WordPress that adds your text or logo watermark to photos. Your original files are never touched. Watermarked copies are created the first time an image is requested, stored in a cache, and swapped into your pages at output time.

With this design:

• No “restore” needed. Originals stay exactly as uploaded, so there is nothing to undo.
• No quality loss on your originals. Only the copy is re-encoded, at a quality you choose.
• Deactivate = instantly clean. Turn the plugin off and visitors get the untouched images straight away.
• Works whatever way the image got in. Because it acts on the URL, it does not matter whether images arrive through the Media Library, an importer, a gallery block or a regenerate-thumbnails run.
• Modern formats. JPEG, PNG, WebP, AVIF and (static) GIF.
• Any language. Bundled fonts cover Latin, Cyrillic and Greek.

Features

• Text watermark and/or logo watermark (up to two layers).
• Live preview rendered by the same engine that creates the real copies.
• Nine-position placement, margin, opacity, rotation.
• Size relative to each image, with minimum and maximum limits.
• Choose which image sizes get a watermark and skip small images.
• “Do not watermark this image” switch on every attachment.
• Text tokens: {site}, {year}, {url}.
• Works with GD or Imagick (chosen automatically); EXIF orientation is respected.
• Site Health checks for the image library, cache folder and delivery.
• Automatic fallback for hosts that do not pass missing image URLs to WordPress.

Need several watermark profiles, unlimited layers, or rules that pick a watermark by post type, category or file type? They are in Filigrane Pro, a separate, optional add-on. Everything described above works fully in the free plugin, with no restrictions or nag screens.

External services

This plugin does not connect to any external service. No data leaves your site. Watermarked copies are stored in wp-content/uploads/wmguru-cache.
