What Watermark an Image is for
Photographs travel further than the page they were published on. A mark will not stop anyone determined, but it survives the screenshot-and-repost route that most images actually take, and it tells anyone looking where the picture came from.
How to use it
- Add your files. Drop them on the page or choose them. They stay on your device.
- Set the output format and quality. The defaults suit most files.
- Press convert and save the results, individually or as one ZIP.
Questions
What size should a watermark be?
The sizes here are percentages of the image rather than pixels, so the same settings look right on a phone screenshot and on a forty-megapixel photograph. Five per cent for text and about eighteen for a logo is a reasonable place to start.
Should it be opaque?
Rarely. Around seventy per cent is readable without dominating the picture. Full opacity draws the eye to the mark rather than the photograph, which is usually the opposite of what you wanted.
Can it be removed?
By someone determined, yes — anything drawn on top of a picture can be painted out, and a corner mark is easy to crop off. A mark across the middle is harder to remove and harder to look at. It is a deterrent rather than protection.
Can I watermark a whole folder at once?
Yes. Add as many images as you like and each is stamped with the same settings.
