What does Image Watermark do?
It stamps a text or logo watermark onto one image or a whole batch, directly in your browser. Every output keeps the original width and height, and nothing is uploaded.
How to watermark images
- 1.Drop, browse, or paste up to 50 images (or add the sample).
- 2.Choose Text and type your notice, or choose Logo image and add a PNG or SVG logo.
- 3.Pick one of nine positions or Tile, then adjust opacity, size, rotation, and margin or tile spacing while watching the live preview.
- 4.Choose the output format and click Apply watermark.
- 5.Download single files or everything as a ZIP.
How the options scale
Size, margin, and tile spacing are percentages of each image width, so the same settings look consistent on a small thumbnail and a large photo in one batch. For text, size is the font size; for logos, it is the logo width with its aspect ratio kept. Opacity runs from 0 (invisible) to 100% (solid). Text uses system fonts (sans-serif, serif, monospace, Arial, Georgia, Verdana) with five weights and any hex color.
Limits and privacy notes
Images up to 50 MB and 100 megapixels each are supported. The logo is decoded once and reused for every file. Keep original saves PNG, JPEG, and WebP in their own format; GIF, BMP, AVIF, and SVG inputs are saved as PNG, and animations keep only the first frame. A visible watermark discourages reuse but can be cropped or edited out, so it is not copy protection. Exported files do not keep the original metadata.
