PROCESSING TRANSPARENCY
Trust center ↗Know what happens before you upload.
A temporary per-request workspace is cleaned when processing ends.
A visible watermark does not prevent cropping or advanced editing and is not DRM. Very long text can be unsuitable for small images.
Check contrast over both bright and dark areas and make sure the mark does not cover important content before publishing.

INFINITY INTELLIGENCE
A copilot that understands this tool.
Ask what a setting means, whether this is the right tool, how to recover from an error, or what to do with the result next. Infinity receives safe context from this page — not the file contents automatically.
PRACTICAL CONTEXT
What this tool is good at — and where to be careful.
When this tool makes sense
Adding a short name or phrase as a visible watermark before publishing an image or sending a preview copy.
What the engine actually does
A transparent overlay is created above the source image, the text is drawn near the lower corner on a translucent dark backing, and the final image is saved as PNG. The watermark becomes part of the output pixels.
What it does not promise
A visible watermark does not prevent cropping or advanced editing and is not DRM. Very long text can be unsuitable for small images.
A 20-second quality check
Check contrast over both bright and dark areas and make sure the mark does not cover important content before publishing.
Frequently asked questions
Does it stop image theft?
It is a visible deterrent, not a technical system that prevents copying.
What is the output format?
The result is PNG to preserve the rendered overlay cleanly.
