Before you start
Add your name, handle or proof label to one image. Set the text, requested font size, color and opacity, then compare the exported PNG with the source. The label sits inside the lower-right edge; check contrast and whether it covers important detail.
How to use this tool
- Choose a static image.
- Enter the text and adjust the visible font-size, color and opacity controls.
- Select “Add image watermark”, inspect the result, then save the output you need.
Supported inputs and limits
One static PNG, JPEG or WebP up to 20 MiB and 16 million pixels. Output is PNG; source metadata is not retained.
Text is reduced to fit inside the image. If it cannot fit at 8 px, use shorter text or a larger image. This visible mark can be cropped or edited away; it does not prevent copying.
Custom text only. No automatic date or EXIF text, uploaded logo, batch processing, or copyright enforcement.
