Add a text watermark to one or many photos at once — free, nothing uploaded.
A watermark deters casual image theft and reinforces attribution when photos are shared or reposted — commonly used by photographers, small businesses listing products, and anyone sharing preview images publicly before a sale or full release.
This version supports text watermarks only — a logo/image watermark option may be added in a future update.
No — the original image is unchanged apart from the watermark overlay; output is saved as PNG, so there's no additional compression loss.
40-60% is a good default — visible enough to deter casual reuse, but not so strong it obscures the photo underneath.
