How to add a watermark to images
Use this tool to add a text or image/logo watermark to the images you load. Adjust the watermark, review the live preview, and apply it to one image or a batch.
Choose a text or image watermark
- Drop one or more images onto the drop zone, or click browse files.
- Under Watermark type, choose Text or Image / logo. In Text mode, enter up to 80 characters in Watermark text. In Image / logo mode, click Choose image and select the watermark image.
- Set Opacity, Size, and Rotation. Choose a point in the Position grid, then select Single or Tiled under Repeat.
- Review the live preview; watermarking updates automatically as files and settings change.
- When batch output is available, click Download all as ZIP.
Adjust watermark placement and appearance
In Text mode, set Watermark text, Font, Bold, and Text color. The preview updates as you change the settings.
- Set Opacity from 5–100%, Size from 5–80%, and Rotation from −90° to 90°.
- Position uses a nine-button grid.
- Single places one watermark. Tiled repeats it across the image.
- Tile spacing appears when Tiled is selected and ranges from 50–300%.
Apply the watermark
Load one image for a single result or multiple images for batch processing. The file list shows File, Original, Output size, and Status. Processing updates automatically as files and settings change. For a processed batch, click Download all as ZIP.

Frequently asked questions
Can I watermark many images at once?
Yes. Load multiple images, set up the watermark, then click Watermark all to apply the current settings to the batch. Use Download all as ZIP for the batch download.
What is tiled watermark mode?
Instead of placing one watermark in a single spot, Tiled repeats it across the image. Tile spacing controls the distance between repeated watermarks.
Can I save my watermark settings for later?
Yes. Enter a value in Preset name and click Save preset. Saved presets appear in the Watermark presets area for reuse.
