What does this tool do?
Batch-add text or logo watermarks to protect copyright or credit a source: set font size, color, opacity, rotation and tile density, then tile across the whole image or place it in one of nine grid positions (e.g. bottom-right). Preview on the left, apply to every image at once, then download individually or as a ZIP; the images never leave your device.
FAQ
What is the difference between tiling and grid positioning?
Tiling repeats the watermark across the whole image, which protects the entire piece and stops anyone cropping the credit away. Grid positioning places a single watermark at one of nine anchor points (bottom centre, bottom right, …), which looks cleaner when you are showcasing the work.
How do I make the watermark less obvious, or more visible?
Opacity is the main lever: 100% is fully opaque, 5% is nearly invisible. Font size controls how much of the frame it covers, and the rotation angle (-90° to 90°) lets a diagonal mark span more area without hiding the subject.
Can I add text and a logo at the same time?
Yes. Text and the logo image are separate inputs and can both be enabled with their own position and opacity. For a purely graphical mark, generate a transparent PNG with the e-seal or signature maker and upload it here.
Which formats can I export?
PNG or JPG. PNG preserves the semi-transparent watermark without quality loss; JPG gives a much smaller file for social posts or email, but you need to pick a background colour for transparent areas.
Are my images uploaded?
No. Previewing and exporting happen locally in your browser; your images never leave the device.
