Batch watermark hundreds of photos with text — full control of position and style. Every tool below runs locally in your browser — batch, free, no signup, no watermarks.
A watermark is a policy, not a decoration: visibly enough to deter theft, subtly enough not to ruin the image. The Image Watermark tool gives you full control — text, font, size, color, opacity, rotation and position with a live preview — and applies the identical mark across hundreds of photos in one batch pass. Centered or diagonal text at 8–15% opacity survives the crop-and-repost cycle that kills corner marks.
Run portrait and landscape sets as separate queues with margins tuned per orientation, and keep watermark-free masters in a separate archive for the day you license or print. The reverse operation lives in the AI category — Watermark Remover cleans marks from images you own — and Image Overlay handles logo stamps where the mark is a file rather than text. All processing is local, so unreleased work stays unreleased.
