Batch photo watermark tool

Add Watermark to Images

Set the watermark once and apply it relative to each image size, so mixed-resolution files keep a consistent visual treatment.

How it works

From source files to finished batch

Add the images to mark

Import one photo or a full batch. Every source remains untouched and stays in browser memory.

Place it directly on the image

Drag text or a logo to move it, pull the top handle to rotate, and drag the corner to resize. The editor uses the image after earlier workflow steps. Fine numeric controls and placement presets remain available.

Process the batch

The same relative rule is drawn into each image and the finished pixels are exported in your selected format.

Common uses

Built for everyday image work

Proof and review images

Tile a subtle text mark across preview images before sending them for selection.

Marketplace photos

Place a small logo at the same relative corner across mixed product resolutions.

Event galleries

Add a consistent credit line to a batch before publishing or sharing.

Worth knowing

Keep the output predictable

Relative sizing

Text and logo size are calculated from each image, so a 6% text setting remains visually consistent across resolutions.

Logo transparency

Use a transparent PNG or WebP logo to avoid a visible rectangular background.

Watermark limits

A watermark can communicate ownership but cannot technically prevent copying or removal.
