How it works
- Choose one or more images (JPG, PNG, WebP).
- Enter a text or choose a logo, then set position, size, opacity and angle – the preview updates live.
- Click “Add watermark” and download the images.
Notes and limitations
- The watermark becomes part of the pixels. It deters casual reuse, but can be removed with image editing – it is no technical copy protection.
- “Tiled” repeats the watermark across the whole image, which makes removal harder.
- For logos, a PNG or SVG with a transparent background works best. The size refers to the image width.
Frequently asked questions
Will my originals be changed?
No. New files are created; your originals stay untouched on your device.
