How do I add a text watermark to images?

Choose your files and enter the watermark text. Set the text position, opacity, size, and color before generating the results.

Why does the watermark show the image filename?

The use-filename option inserts each file’s name. Disable that option when every image should use the same custom watermark text.

Does a visible watermark prove ownership or prevent copying?

No. It adds a visible mark to the image. It does not establish legal ownership or prevent someone from copying or altering the pixels.
