How to watermark an image
- Choose a JPG, PNG, or WebP image.
- Type your watermark text and adjust size, opacity, rotation, and color.
- Pick a single corner/edge position or a tiled pattern, then download.
Why use this private image watermarker?
Your photo stays on your device while the canvas draws the watermark. The live preview always matches the downloaded file exactly.
Single position vs. tiled
A single position works well for a small logo mark or copyright line in a corner. A tiled pattern repeats the text diagonally across the whole image, making it harder to crop out — useful for draft or confidential previews.
Common use cases
- Mark portfolio photos before sharing previews
- Add a copyright or brand name to product images
- Stamp draft or confidential text across screenshots
Frequently asked questions
Are my images uploaded?
No. Reading, watermarking, previewing, and downloading happen locally in your browser.
Can I watermark with my own logo image instead of text?
Not yet — this tool currently supports text watermarks only.
Can I control the watermark position?
Yes. Choose one of nine anchor positions, or switch to a tiled pattern that repeats across the whole image.
Which formats are supported?
You can open JPG, PNG, or WebP images and export as JPG, PNG, or WebP.
Does watermarking change the image dimensions?
No. The output keeps the exact same pixel dimensions as the source image.
