Why photographers & sellers love this
Batch watermarking
Drop 50 product photos at once. One click applies your logo or text to every image and downloads them individually — saves hours every week.
PNG logo transparency
Upload a .png logo with a transparent background and it composites cleanly over any image — no white box, no messy edges.
Text with shadow
Text watermarks include an optional drop shadow so they stay readable on both light and dark images — no more invisible white text.
Tiled / repeating
Enable Tiled mode to cover the entire image with a repeating watermark grid — makes it much harder to crop out or remove.
100% private
Everything runs in your browser via Canvas API. No server, no upload, no account. Watermark confidential work without any risk.
Full control
9-point position grid, custom size %, opacity, rotation, and padding margin. Dial it in exactly how you need it — not just a one-size preset.
