How to watermark an image
A watermark makes it clear who a photo belongs to and makes it harder to reuse without permission: product photos, portfolio shots or a copy of a document you send for a specific purpose.
Choose one or more images.
Type a text, pick a stamp or upload your logo, and adjust position, opacity, size and angle while watching the preview.
Press Add watermark and download the image or, if there are several, a ZIP with all of them.

Frequently asked questions
Yes. Choose all the images at once: the watermark is applied with the same settings to each one and they download together in a ZIP. Size and position are relative to each image, so it looks the same even with different resolutions. You can check the preview of each photo with the arrows.
The original resolution is kept. You can keep each file’s format (JPG, PNG or WebP) or convert them all to JPG, PNG or WebP; GIF, BMP and AVIF are saved as PNG. JPG and WebP are saved at high quality (92%) and PNG losslessly. Images are re-encoded, so EXIF metadata is not kept.
No. The photos and the logo are processed in your own browser and are not sent to JapalTools or anyone else.
