Spent hours on an image only to see someone else use it? Adding a watermark is one of the most effective anti-theft methods. Here's how to add a watermark — text, logo, and batch watermarking dozens of images at once.

Why add a watermark

  • Anti-theft: marks the source, discourages unauthorized use
  • Branding: every image is brand exposure
  • Copyright: states ownership, avoids disputes
  • Prevent misuse: harder to use commercially without permission

Add a watermark to any original image you publish online.

Text or logo watermark?

Text watermark — your brand name, nickname, or URL. Simple and direct, great for individual creators.

Logo watermark — your brand logo. More professional and recognizable, ideal for businesses.

Add a watermark with PixelForge

Open the PixelForge Batch Watermark Tool — local processing, no upload.

Step 1: Upload your images (batch supported). Step 2: Enter text or upload a logo; set position, size, and opacity. Step 3: Apply to all images and download. Dozens of images in one go.

Tips

  1. Place at the visual center — corners are easily cropped
  2. Moderate opacity — visible but not distracting
  3. Full-image tiling for key images
  4. Keep the clean original as a backup

FAQ

Where should I place a watermark for anti-theft?

At the center or visual focus, since edges are cropped first. For important images, use [tiled watermarks](https://img-tools.top/watermark) across the whole image to prevent cropping.

Can I watermark many images with the same mark at once?

Yes. Batch upload lets you add the same watermark to many images, perfect for creators and e-commerce.

How big and how transparent should a watermark be?

No fixed standard. Generally 1/4 to 1/3 of image width, at 30%-60% opacity — clearly visible but not covering the subject. For anti-theft, go bigger and tile it.

Will a watermark ruin the image?

No, if set well. Low opacity in a corner protects without ruining the picture. Increase the watermark for key images.
