How to use it
- Drop photos onto the page or click to choose them. Several at once is fine.
- Type your text and adjust size, opacity, color, rotation and position — the preview updates instantly.
- Optionally add a logo PNG with its own size, opacity and position.
- Save each photo individually, or use "Save all" when you have several.
Text and logo sizes are set as a percentage of the photo's width, so a batch of photos with different resolutions gets a watermark of similar visual size. Any language works, including Korean.
Position options
| Position | Good for |
|---|---|
| Bottom right / bottom left | Credit lines on blog and social posts |
| Top left / top right | Logos and branding |
| Center | Drafts and sample images |
| Tiled pattern | ID copies or original photos you sell — hard to crop out |
When sending a copy of an ID or bank document, a tiled line such as "For ABC rental application only" makes it much harder to reuse elsewhere.
Output format and quality
| Original | Saved as |
|---|---|
| JPG | JPG (92% quality) |
| PNG | PNG (transparency kept) |
| WebP | WebP (92% quality) |
| Other formats | PNG |
The preview is drawn at reduced size for speed, but saving redraws the image at its full original resolution. Files are named original-name-watermark.jpg.
Good to know
- Photos are never uploaded; everything is processed in this browser.
- A watermark discourages reuse but cannot stop it entirely. Corner marks are easy to crop, so use a semi-transparent tiled pattern when protection matters.
- Extremely large images (tens of megapixels) may fail to save depending on your device's memory.
Next, shrink the file with the image compressor or change its dimensions with the image resizer.
