Text or logo, and where it sits
Two kinds of watermark are available and you use one at a time. Text mode takes whatever you type and draws it in a clean system typeface, with a color picker and an optional soft shadow that is switched on by default. That shadow is what keeps white text legible over a bright sky, and it is worth leaving on unless it clashes with your design. Logo mode takes a second image file, usually a PNG with transparency, and draws that instead. Picking a logo switches the mode automatically.
Six placements are offered: the four corners, the center, and tile. The corner options sit inside a margin of 3.5% of the shorter edge, so the mark keeps a consistent inset whether the photo is landscape or portrait. Tile repeats the watermark across the whole frame, spaced so it still covers everything when rotation is applied.
Size runs from 2% to 40% and starts at 6%. For text it is measured against the shorter edge of the image, and for a logo against the width, so the mark scales with the picture instead of being fixed in pixels.
- Text mode with a color picker and optional shadow
- Logo mode using your own transparent PNG
- Four corners, center, or tiled across the frame
Getting the opacity right
Opacity runs from 0.05 to 1.0 and starts at 0.45, which is deliberately in the middle. This is the setting that decides whether the watermark does its job, and it is the one people get wrong in both directions.
Too faint and it can be removed in seconds, or simply cropped out if it is tucked in a corner. Too strong and it ruins the photo you were trying to show. The pattern that actually works against casual reuse is a tiled watermark at low opacity across the whole frame, because there is no clean crop that removes it and no easy patch that hides it. A single corner mark at 0.45 is a credit line, which is a legitimate thing to want, but it is not protection.
Rotation runs from minus 90 to plus 90 degrees in steps of 5 and applies to both text and logo, including in tiled mode. A shallow diagonal is the conventional choice for tiling because it cuts across image features rather than lining up with them.
What it will not do
Nothing about the placement is automatic. There is no analysis of the picture to find an empty area, no contrast detection to choose a readable color, and no subject detection. You choose the anchor and the tool applies the same margin formula every time, which means a mark in the bottom right corner can land on top of something important and you have to move it yourself.
It handles one image at a time. There is no batch mode for a folder, no saved watermark preset, and no font picker: the typeface is fixed to a clean system stack. Export is PNG or JPG only, with no WebP option, and there is no positioning by numeric coordinates.
It is also worth being realistic about what a watermark achieves. It deters casual reuse and makes an unattributed copy obvious, but it does not prevent anyone from taking the image, and a determined person with an editor can remove most watermarks. Treat it as attribution and friction rather than as protection.
- No automatic placement, contrast, or subject detection
- One image at a time, no batch queue
- PNG or JPG export, no WebP, no saved presets
