A watermark is the simplest protection when selling products, publishing a portfolio or sending previews: scrubbing half-transparent text off the whole frame is harder than contacting the author. Font size adapts to the frame automatically; the mark repeats along the diagonal. Runs free on Zerocoder's servers, nothing stored. Before publishing, compress the photo and fit the size to the platform. The rest of the free tools are in one section; AI image generation — in the Zerocoder Studio.

Watermarks for selling products and services

Product photos get copied from listing boards — along with your shooting effort. A mark with a phone or handle makes the copy useless: the buyer still reaches you. Watermark every listing photo; send clean versions only to a real buyer on request.

Portfolios and client previews

Standard practice for photographers and designers: watermarked previews before payment, the clean file after. A half-transparent diagonal doesn't block judging the work but rules out “thanks, we'll take it from here”. A domain in the mark also brings new clients from reposts.

What a watermark does not guarantee

A mark is a barrier, not armour: corner labels get retouched away, which is why we lay the text across the whole frame with repeats. For extra protection publish a downsized copy and keep the full-resolution original to yourself — resize handles the public copy.
