How to use Watermark Image
- Add one or more pictures.
- Type your watermark text or choose a logo, then set the position, size and opacity. The preview shows the first picture.
- Select Add watermark and download the pictures one by one or as a ZIP.
How it works
The watermark is sized as a share of each picture’s width, so it looks the same on a small web image and a large camera photo in the same batch. A corner position keeps a small margin from the edge. Repeat across the whole picture tiles the mark diagonally, which is much harder to crop or paint out than a single mark in a corner.
The work is done by your browser on your device. Your pictures are not uploaded, so there is no queue, no size limit set by us and no copy kept anywhere. Pictures are processed at their full resolution; the preview is a reduced copy.
A visible watermark discourages casual reuse and tells people where a picture came from. It does not prevent copying, and a determined person can remove a small corner mark. For proofs sent to clients, the tiled layout at 20–30% opacity is the usual choice.
Example
A photographer’s 40 proofs: text “© Studio Name”, repeated across the picture at 25% opacity, saved as JPG and downloaded as one ZIP.
Frequently asked questions
Can I watermark many photos at once?
Yes. Add as many as you like; the same watermark is applied to each, scaled to its size, and you can download everything as a ZIP.
Can I use my logo?
Yes. Choose "Logo picture" and select the file. A PNG with a transparent background looks best.
Will the watermark reduce photo quality?
JPG and WebP photos are re-saved at high quality (92%), which is visually lossless in normal viewing. Choose PNG to avoid any re-compression.
Can a watermark be removed?
A small mark in a corner can be cropped or edited out. A semi-transparent mark repeated across the picture is far harder to remove cleanly.
Can you remove a watermark from a picture?
No. This tool only adds watermarks.
Limitations
