Image Watermark Adder

How text watermarking works in seconds: Select any JPG, PNG, WebP, or GIF image under 25 MB, type copyright or brand text up to sixty characters, choose one of seven anchor positions, and set opacity from ten to one hundred percent. The browser draws bold white type with a dark contrast stroke sized to the shorter image edge, then exports a watermarked JPG, PNG, or WebP in seconds at $0 cost, free and instantly offline with no signup required ever.

Position, opacity, and legibility controls: Seven anchors cover top-left, top-center, top-right, center, bottom-left, bottom-center, and bottom-right, with a four percent margin from the shorter edge so placement stays consistent across batches. Font size follows max 14 pixels or min dimension divided by sixteen, while stroke width scales for contrast on light and dark backgrounds. Opacity between forty and seventy percent protects previews, while fifteen to thirty percent gives elegant branding that never overwhelms composition.

Austin portfolio protection: On 09/21/2026, an Austin wedding photographer stamping a $500 client gallery with bottom-right copyright at sixty percent opacity processes fifty proofs in minutes without uploading sensitive faces anywhere. The local Canvas pipeline keeps every original on the machine, satisfying confidentiality clauses in professional service agreements while deterring casual screenshot theft before final payment clears.

Chicago and Miami proof branding: On 09/19/2026, a Chicago design studio marks $300 worth of concept previews with a centered thirty percent PREVIEW notice that survives cropping far better than corner stamps. A Miami commercial studio the same week brands $1,200 in wedding proofs with a subtle forty percent center mark, balancing theft deterrence against the romantic mood clients expect when sharing galleries with relatives.

Denver and Seattle documentation marks: A Denver software team watermarks $150 worth of technical screenshots with version numbers at twenty percent opacity so leaked images stay traceable across support tickets. A Seattle startup stamps $400 in investor deck exports with CONFIDENTIAL at fifty percent, ensuring forwarded slides always carry provenance. Visible marks deter casual misuse socially, though formal copyright registration remains the real legal protection for high-value work.

New York editorial credits and privacy: On 09/20/2026, a New York picture desk credits a $200 licensed stock photo with a discreet twenty percent bottom-center byline for internal layout review, keeping the composition fully evaluable. Nothing uploads, nothing is logged, and the tool adds no secondary branding of its own. Stamp the text, download the file, and distribute proofs with consistent professional attribution.
