Add Watermark to Image
Add text watermarks — corner placement or a tiled diagonal pattern — with size, opacity and color control.
About this tool
A watermark is the simplest ownership claim an image can carry: your name, brand or © line, visible enough to credit you and deter casual reuse. Photographers watermark portfolio previews, small businesses mark product photos before sharing with clients, and documents get stamped CONFIDENTIAL or SAMPLE before circulating — all use cases where the image is precisely what you don't want passing through someone's server. This tool watermarks entirely in your browser.
Placement comes in two modes. The 9-position grid covers the classic discreet watermark — bottom-right corner being the convention. The tiled mode is the protective one: your text repeated diagonally across the entire image, the pattern used for proofs and confidential documents, because a corner mark can be cropped off in seconds while a tiled one can't be removed without destroying the image.
Size scales with the image width (so the same settings look consistent across photos), opacity runs from a whisper-faint 10% to fully solid, any color is available, and a subtle drop shadow keeps light text legible on light backgrounds. The live preview renders on the actual full-resolution canvas — what you see is exactly what downloads, in the original format.

Frequently asked questions
Where should I place a watermark?
Bottom-right is the discreet convention for credit. But for protection, position matters less than coverage: a corner mark crops off in seconds. Use the tiled diagonal mode when the goal is preventing reuse — proofs, drafts, confidential documents — since removing it means destroying the image.
What opacity should a watermark have?
40–60% suits credit watermarks — clearly visible without dominating the photo. Tiled protective marks often go lighter (20–35%) since repetition provides the coverage. The built-in drop shadow keeps even light, low-opacity text readable on bright backgrounds.
Does a watermark legally protect my image?
It's a deterrent and an ownership statement, not a legal mechanism by itself — copyright exists automatically when you create an image. A watermark makes ownership visible, deters casual copying, and in some jurisdictions its deliberate removal strengthens an infringement claim. For commercial work, registration provides the strongest protection.
Are my photos uploaded when I watermark them?
No — the entire process runs on a canvas in your browser. That matters doubly here, since watermarking often involves exactly the images you're being careful about: client work, unreleased products, confidential documents.
