How to Watermark Photos in Bulk (Free & Private)

Professional photographers know the pain: you shoot 500 photos at an event, edit them, and then need to watermark them all before sending proofs to the client. Using Photoshop actions is slow, and online tools usually require you to upload your gigabytes of data to their server.

The "Local" Advantage

Our Batch Watermarker runs in your browser. This means:

  1. Speed: No upload time. The tool reads files from your disk instantly.
  2. Privacy: Your client's photos never leave your computer.
  3. Cost: It's 100% free.

How to Watermark 50+ Photos at Once

Step 1: Open the Tool

Navigate to the Watermark Tool.

Step 2: Select Images

Drag and drop your entire folder of JPGs or PNGs. Don't worry about quantity—our engine handles it.

Step 3: Customize Your Mark

  • Text Mode: Type your copyright (e.g., "┬® 2026 Studio Name"). Choose a font and color.
  • Logo Mode: Upload your transparent PNG logo.
  • Positioning: Use the 9-point grid to snap the watermark to the bottom-right or center.

Step 4: Batch Export

Click "Download All". We'll zip them up into a single archive for you.
