Create my albumAdd a watermark to multiple photos
A signature or logo helps identify photos you publish. Set its position, opacity and size, then review it on different images. Downloads contain new copies with the watermark baked into the pixels. Keep originals for delivery without a signature.
Example: prepare a reportage selection with the studio name in the bottom right, then export copies for your website or a client presentation.
How to use this tool
- Add photos and enter a signature or upload a logo.
- Set position, opacity and size while reviewing the preview.
- Download the marked copies and keep originals separately.
Frequently asked questions
Can I use a transparent logo?
Yes. A transparent PNG avoids a white rectangle around the logo. Adding a logo replaces the text signature.
Does a watermark completely protect a photo?
No. It helps identify images and discourages reuse, but editing can hide it. It does not replace rights management or access controls.
Are originals modified?
No. The tool exports copies. Unlike a gallery display overlay, this watermark is embedded in the downloaded files.
