PixelStamp Watermark

PixelStamp Watermark is an image protection and watermarking solution for WordPress. It helps photographers, bloggers, agencies, and shop owners protect creative work with fully customizable text watermarks.

You can watermark images automatically when they are uploaded, or process selected images—or your entire media library—in bulk from a dedicated admin screen. A live preview lets you adjust text, colors, position, and styling before you commit changes.

The plugin uses a non-destructive workflow: it creates a secure backup of each original file before applying a watermark, so you can restore the untouched image at any time with one click.

Ideal for:

• Photography portfolios and galleries

• Blog posts with original imagery

• WooCommerce or catalog product photos

• Stock-style sites that need consistent branding

• Teams that want automatic protection on every new upload

Requirements

Before installing, confirm your hosting environment meets these requirements:

• WordPress 5.0 or higher

• PHP 7.4 or higher (PHP 8.x recommended)

• PHP GD extension enabled (required for image processing)

• Writable wp-content/uploads directory

• Sufficient disk space for backup copies of processed images

Recommended:

• Use contrasting watermark colors on light or busy backgrounds

• Test on a single image before running “Apply to All”

• Clear site, browser, or CDN cache after bulk processing if old images still appear

Configuration

After activation, configure your global watermark defaults:

• Go to PixelStamp in the WordPress admin sidebar.

• Under Configuration Settings, enter your Watermark Text (e.g. © Your Name or your site URL).

• Choose Font Family, Font Size, Text Color, and Opacity.

• Select a Watermark Position (bottom-right is recommended for most photos).

• Optionally enable Background Box for better readability on busy images.

• Adjust Spacing & Offset, Rotation, and Scale if needed.

• Watch the Watermark Preview and Live Preview panels update as you type.

• Enable Auto-apply Watermark on Upload if you want every new image protected automatically.

Settings are saved as you change them; you do not need a separate “Save” button for the form fields.

Usage

Watermark selected images

• Open PixelStamp in the admin menu.

• Click Open Media Library and select one or more images.

• Review the live preview on the right.

• Click Apply Watermark.

• Watch the Status & Progress panel and toast messages for feedback.

• Check the image in Media → Library or on the front end of your site.

Watermark your entire library

• Configure your watermark settings first (see Configuration above).

• Click Apply to All and confirm the prompt.

• Wait for the progress bar to complete—large libraries may take several minutes.

• Re-check a few random images to confirm the watermark looks correct.

Restore original images

• Select the same image(s) in PixelStamp.

• Click Restore Originals.

• The plugin copies the backed-up file back and regenerates thumbnails.

• Backups are removed after a successful restore for that file.

Auto-apply on new uploads

• Enable Auto-apply Watermark on Upload under Global Settings.

• Upload a new JPEG, PNG, or WebP file through Media → Add New.

• The watermark is applied automatically when WordPress generates attachment metadata.

Note: Use the PixelStamp admin screen to apply watermarks. The standard “Edit Image” control in the block editor does not run this plugin’s batch tools.

Backups & file storage

• Original files are copied to wp-content/uploads/pixelstamp-watermark-backups/ before the first watermark is applied.

• Each backup uses the original filename plus a.bak extension.

• Restoring replaces the public file and deletes that backup entry.

• Keep adequate disk space when watermarking large libraries.

Support

For setup help, review the Installation, Configuration, and Usage sections above. If watermarks fail to apply, verify PHP GD is enabled and that your uploads folder is writable.
