Add a Watermark to Photos in Batch

A free tool that adds your watermark (text or logo) to your images in batch, or blurs a region to hide sensitive information. Everything inside your browser with no uploads.

Let's be honest: there is no absolute protection for any published image. But a watermark does three realistic things — it deters lazy theft, it credits you wherever the image travels, and it markets you for free with every share.

Balance matters: too light and it is easily cropped, too heavy and it ruins the image. Opacity between 30% and 45% suits most cases, and tiling across the whole frame is hardest to remove — ideal for preview images before purchase.

How to use it — step by step

  1. Choose the mode: “Add watermark” or “Blur a region”.
  2. Drop a single image or several at once.
  3. Type your watermark text or upload your logo, then set size, opacity and position.
  4. Enable “Tile across whole image” for stronger protection if you wish.
  5. Download one image, or all of them as a ZIP.

Why processing inside your browser?

Your image never leaves your device. Most competing sites upload your photos to their servers to process them; this tool runs entirely in the browser. No upload, no account, no waiting and no limits — because your own device does the work.

Frequently asked

What opacity should I use?

30–45%. Less is barely visible, more is intrusive.

Where should I place it?

Corners are the easiest to crop. For serious protection place it near the centre or tile it.

Can I remove a watermark from an image?

The “Blur a region” mode hides one manually. Full AI removal is a different service.

Does it work on several images at once?

Yes, settings apply to all, with a single ZIP download.
