How to Watermark Photos Against Theft — Position & Opacity Tips
Watermarking your own photos or work before posting them online deters unauthorized use — but only if the position and opacity are actually set up right.
When you need a watermark
Sample images on a stock photo platform, a public portfolio, or work you post to social media — anywhere the original spreading unrestricted would be a problem — is where a watermark earns its keep. It doubles as a copyright notice too.
Setting position and opacity
A small mark tucked in one corner gets removed with a single crop. If deterring theft is the actual goal, tiling the mark diagonally across the whole image is far more effective. Keep opacity too high and it ruins the photo; too low and it's trivial to erase — 20–35% is usually the sweet spot.
Tiled repeat vs. a single mark
| Approach | Trade-off |
|---|---|
| Single mark in a corner | Looks cleaner, but one crop removes it |
| Tiled repeat | Survives cropping, much stronger deterrent |
Applying it to a whole batch at once
If dozens of photos all need the same text and position, setting it up once and applying it to the whole batch is far faster than watermarking each one individually.

Pixzero's watermark tool supports position, size, opacity, rotation, and tiled repetition, and can process a whole batch of photos at once.
