The short answer
Why use Add Watermark?
Photos posted to a marketplace or a portfolio get reused without credit, and a single corner mark is easy to crop away. A faint mark repeated across the picture is much harder to remove, and the preview shows exactly how it looks before you save.
There are five settings: Text, which reads ExtractPics until you replace it, Text size from 10 to 180 starting at 42, Text color, white by default, Layout, and Opacity from 5% to 100% starting at 35%. Size is measured against a 1400 pixel long side, so 42 becomes an 84 pixel font on a 2800 pixel photo, which keeps the mark the same share of small and large images.
Layout starts on Repeat across the image, which writes the text over and over on a grid turned 30 degrees, with every other row shifted by half a step so the marks never line up in columns. That is much harder to crop or clone out than one mark. Bottom-right corner places a single line near the corner instead. Both use a bold system font with a dark outline.
The result is always a PNG, which can be heavier than the JPEG you started with; run it through Compress Image for a small file. Add Text to Image writes one fully opaque line in the corner for captions, and Add Timestamp stamps a date there. Add Logo is the one to use for an image mark.

Add Watermark tips
- On bright skies or white products, switch Text color from white to a dark shade.
- In the repeated layout, a size of 24 to 40 gives a fine pattern; bigger text means fewer rows.
- Type the © symbol from your phone keyboard; the default placeholder hints at it.
- Short marks like a handle stay at full size, while long sentences shrink to fit the width.
