How it works
Drop in images
Up to 10 — JPG, PNG, or WebP.
Set the watermark
Text or a logo file, plus position, size, color, and opacity.
Download each
Stamped images in their original format.
Add a text watermark — your name, "DRAFT", a copyright line — or a logo image, positioned in any corner or center, or tiled diagonally across the whole image. Control the size, color, and opacity; apply it to up to 10 images at once.
Watermarks discourage casual reuse — they do not prevent determined copying, and anything semi-transparent can potentially be edited out. If you need the strongest protection, keep originals private and share watermarked previews.
Questions, answered
Text is fast and readable at any size; a logo looks professional but needs a transparent PNG to sit nicely over a photo.
