Add Text Watermark to Images — Bezplatný Online Tool

Protect and brand your photos with a text watermark using our free watermark image tool on XConverters. Default text is © XConverters — customize it, set opacity from 10% to 90%, and download JPEG, PNG, or WebP output entirely ve vašem prohlížeči. Bez účtu, bez nahrávání, zcela zdarma.

Co tento nástroj dělá

Watermarks deter casual copying and signal ownership on portfolio shots, stock previews, and social posts. A semi-transparent text overlay across the image makes reuse obvious while keeping the picture visible for review. Our tool renders your caption on the canvas locally so you control wording and strength without Photoshop.

Opacity ranges from 10% for subtle credits to 90% for strong preview protection. Choose JPEG, PNG, or WebP export depending on whether you need transparency or smallest file size. Processing stays on XConverters ve vašem prohlížeči — client photos and unreleased campaign assets never upload to a server.

The default © XConverters label demonstrates placement; replace it with your name, studio, or URL. Free, instant, and no registration — ideal for photographers, designers, and marketers who need quick branded exports.
