Watermark an Image — Free & Private
Stamp a text watermark onto your image — pick the position, color, and opacity. Everything runs locally — nothing is uploaded.
Frequently Asked Questions
Does this upload my image to a server?
No. The watermark is drawn onto the image entirely in your browser using the Canvas API. Your image is never uploaded or transmitted anywhere.
Can I watermark with a logo image instead of text?
This tool currently supports text watermarks only — a good fit for copyright notices, names, or usernames. Image/logo overlays may be added in the future.
Where can I place the watermark?
Choose any of nine positions — the three rows (top, middle, bottom) crossed with three columns (left, center, right) — plus font size, color, and opacity.
Need to capture a webpage too?
Full Page Capture exports any webpage as a screenshot or PDF — then watermark it right here.
