How to Watermark Images
Updated 2026-09-13 · DocsAll Guides
Quick answer: Protect photos with a text or logo watermark — single images or batches. Open 图片水印 — everything runs locally in your browser, and files never leave your device.
Steps
- Upload images to the Watermark tool.
- Choose text or upload a transparent PNG logo.
- Set position, opacity, and optional tiling across the whole image.
- Download the watermarked images.
Important notes
- For deterrence, tiled semi-transparent (30–50%) watermarks beat a single centered one; a giant centered logo ruins the photo for legitimate viewers too.
- A watermark signals ownership but does not restrict copying — combine it with publishing low-resolution versions for real protection.
Common questions
Can I add multi-line text? Yes, the text box supports line breaks.
Can it remove existing watermarks? No — this tool only adds watermarks.
