About the Add Watermark to Image
A watermark tells people who made a picture and discourages them from using it without asking. This tool puts your text or logo on any number of pictures at once. Type the text, or drop in a logo with a clear background, then choose how big it is, how see-through it is and where it goes: in one corner, in the middle, or repeated across the whole picture at an angle. A soft shadow keeps white text readable on bright photos. The pictures are processed one after another in your browser, with a preview of each result, and you can download them singly or all together in a ZIP. Your photos and your logo never leave your device.

Placement choices
A single mark in a corner is tidy and does not spoil the picture, but it is easy to crop away. A mark in the middle is hard to remove but covers the subject. A repeated pattern at an angle, like the stock photo sites use, is the strongest protection and also the most intrusive, so it suits previews and proofs rather than your final portfolio.
Think about where the picture will be seen. On social media, a small corner mark with your handle is usually enough to make sure people know where it came from.
Tips for a good-looking watermark
- Keep the text short: a name, a website or a handle.
- Use white text with the shadow on for dark and medium photos.
- Use a dark colour for very bright pictures.
- Try 5 to 10 percent size for a corner mark.
- For a repeating pattern use a lower opacity such as 25 to 35 percent.
- Keep a copy of the original photos without marks.

Frequently asked questions
Does a watermark really protect my photos?
It discourages casual copying and shows who made the picture, but a determined person can crop or edit it out. Large, repeated, semi-transparent marks are harder to remove than a small one in the corner.
What opacity should I use?
Between 30 and 60 percent is a good balance: visible but not distracting. Lower values suit repeating marks that cover the whole picture.
Which logo format is best?
A PNG with a transparent background, ideally white or dark depending on your photos. The logo is scaled to the size you set.
Will my pictures be made smaller?
Pictures are kept at their original size up to 4096 pixels on the longest side. Larger ones are scaled down to that limit.
What file type do I get?
PNG pictures stay PNG. Everything else is saved as high-quality JPG.
Can I add the watermark to a PDF instead?
This tool works on pictures. For documents, use a PDF watermark tool.
Are my photos uploaded?
No. The marks are drawn on your device and the files never leave it.
