How to use Watermark Images
Add a text watermark to one image or a whole batch.
- Select images, enter watermark text, and choose a size and opacity. The watermark is placed near the lower-right edge of each output.
- Process the selected files, then inspect the preview, dimensions or warnings.
- Download a new copy and check it before replacing or sharing the original.
How processing works
The entered text is rendered with the selected size and opacity near the lower-right edge of each image, and the result is encoded as a new file.
A quick example
Add your shop name to product images before sharing them.
Assumptions, edge cases & limits
- A watermark becomes part of the exported pixels.
- Text may be hard to read on a busy background; inspect every batch result.
- Watermarks do not prevent copying and should not cover important detail.
Questions about Watermark Images
Can I add the same text watermark to several photos?
Yes. Choose a batch and enter one text value with your preferred size and opacity. Preview the placement on images of different dimensions before downloading.
Will a watermark prevent people copying my image?
No. It can show attribution or discourage casual reuse, but it is not copy protection and may be cropped or edited. Keep original files and relevant ownership records.
Are my files or inputs uploaded?
Calculation and file processing run in your browser without a processing upload. Downloads go to your device. Choosing a next-step transfer creates a temporary local copy for that workflow. Region preferences are stored separately from tool inputs. See our privacy details.
Can I use this tool for free?
Yes. No signup, subscription or payment is required to use the tool or download its output. File tools have device and size limits; a smaller batch may work better on a phone.
