Batch Watermark Tool

Features of the Batch Watermark Tool

The Batch Watermark Tool is a free web tool that allows you to add text or logo watermarks to multiple image files (JPG/PNG/WebP) at once and save them. All processing is done in your browser without uploading images to a server. Designed with privacy in mind.

Key Features

• Text Watermark: Insert any text. Color and size are adjustable.
• Logo Image Watermark: Overlay your logo image (PNG, etc.).
• Opacity & Position Control: Freely set the watermark opacity and placement (9 positions).

Use Cases

• Adding copyright notices to photos for blogs and social media to prevent unauthorized use.
• Adding "SAMPLE" labels to product images on e-commerce sites.
• Inserting "Confidential" marks on internal document images.

How to Use

1. Select or drop the original images you want to process.
2. Choose the watermark type (text or image) and configure the settings.
3. Adjust the position and opacity while checking the preview.
4. Click the button to batch process and download.

About Saving Settings

Click the "Save Settings" button to store your watermark settings (text content, color, size, opacity, position, logo image, etc.) in your browser. Your settings will be automatically restored on your next visit, so you don't need to re-enter the same settings every time.

This save feature uses your browser's built-in storage (localStorage), and no settings data is ever sent to a server. You can delete saved settings at any time using the "Reset Settings" button.

Note: There is a file size limit (1MB) for saving logo images. Logo images exceeding this limit will be skipped, and only non-logo settings will be saved. *Logo image saving uses the browser's storage. Even if the image size is small, saving may not be possible depending on browser or device conditions. In that case, only non-logo settings will be saved.
