How to watermark images
- Add images. Up to 10 at once — each gets the same watermark.
- Pick text or logo. Type watermark text with font/color controls, or upload a transparent PNG logo.
- Place it. A single corner via the nine-grid, or tile it across the whole image with angle and density controls.
- Download. Save singles or grab everything as one ZIP.
Single mark vs tiled watermark
Corner watermark
A small mark in one corner — credit your name without distracting viewers. 15–40% opacity usually reads well.
Tiled watermark
Repeating diagonal marks across the whole image — for proofs, previews and content you do not want reused.
Batch
One setting applies to every image in the queue — consistent branding across a whole shoot.
Frequently asked questions
How do I watermark a photo?
Upload your image, type watermark text or upload a logo PNG, pick a corner or tile mode, and tune opacity — the preview updates live.
Text vs logo watermark?
Text watermarks are typed in with font and color controls; logo watermarks stamp an uploaded PNG (transparent works best) with size and opacity controls.
Can I watermark in batch?
Yes — up to 10 images get the same watermark settings at once, then download everything as a ZIP.
How does tiled mode work?
Tiling repeats your watermark diagonally across the whole image with adjustable spacing and angle — good for deterring reuse.
Will the watermark ruin the image?
You control opacity — 15–40% marks ownership without blocking the picture; go lower for tiled mode.
Are images uploaded?
No — watermarking composites locally in your browser.
