About Watermark Adder
A visible mark is a deterrent rather than a lock — it discourages casual reuse without preventing a determined crop. Placing it across the subject instead of in a corner is what makes it awkward to remove.
Overlay a custom text or logo watermark onto your images and documents to mark them as drafts or deter unauthorised reuse. Files are watermarked locally in your browser and never uploaded.
Protect your photos and graphics by overlaying custom text or a logo, then adjust the position, size and opacity until it looks right and download the result. A subtle watermark deters unauthorised reuse of product shots, proofs, screenshots and creative work.
Add a semi-transparent copyright line, or tile a logo across the whole canvas so a crop cannot simply remove it. Position, size and opacity are all adjustable until the mark sits where it does not fight the subject.
