Main features
Watermarking, done properly.
Text watermarks
Set your own text, font, size and colour, then fine-tune the spot with a nine-position grid and a margin.
Image watermarks
Use your logo or any picture as the watermark, with the size relative to the photo, the margin and the opacity each adjustable.
Batch processing
Add many pictures or a whole folder at once; output lands in a "watermarked" folder and the originals are never modified.
Local processing
Watermarking runs entirely on your machine, images are never uploaded, and there is no sign-up or login.
