How to use 添加水印到图像
Steps
- Upload one image or a batch of images.
- Enter watermark text or add a logo layer.
- Adjust opacity, size, rotation, tiling, and position.
- Preview the result and download the watermarked image or ZIP.
Example use case
A photographer can add a low-opacity name in the bottom-right corner of preview images before sending them to a client gallery.
Settings explained
- Opacity controls how strongly the watermark appears over the image.
- Position places a single mark in a corner, edge, or center.
- Tiling repeats the watermark and is useful when screenshots or previews may be cropped.
Limitations
- Watermarks discourage casual reuse but do not provide legal protection by themselves.
- Heavy compression after watermarking can make small text harder to read.
- Batch processing depends on browser memory and image dimensions.
Troubleshooting
- If the watermark is hard to see, increase opacity or choose a contrasting color.
- If it distracts from the image, lower opacity or move it to an edge.
- If batch export is slow, process fewer very large images at once.
常见问题
- Can I batch watermark images?
- Yes. The watermark tool supports multiple images and can export the results together.
- Should I use text or a logo?
- Use text for quick attribution and a transparent PNG logo when you need brand consistency.
