What is an Image Watermark?
An image watermark is a visible overlay (text or logo) placed on an image to identify ownership, protect copyright, or brand your content. Watermarks discourage unauthorized use and help promote your brand when images are shared across the web.
This tool runs entirely in your browser using the HTML5 Canvas API. Your files and logos never leave your device — they are not uploaded to any server, stored, or logged.

Frequently Asked Questions
Is this image watermark tool safe?
Yes. All processing happens entirely in your browser using the HTML5 Canvas API. Your image and logo are never uploaded to any server, stored in any database, or logged. Once you close or refresh the page, no trace of your files remains.
Can I use an image/logo as a watermark?
Yes. Check the "Use logo/overlay image" option after uploading your main image to upload a second image (PNG with transparency recommended) to use as a watermark overlay.
What image formats are supported?
You can upload JPEG, PNG, and WebP images. The watermarked result can be downloaded in your choice of PNG, JPEG, or WebP format with adjustable quality.
What does the "Tiled" position do?
Tiled mode repeats your watermark text across the entire image in a grid pattern. This is useful for creating a repeated background watermark that covers the whole image, often used for "proof" or "draft" watermarks.
Can I adjust the watermark opacity?
Yes. Use the opacity slider (5–100%) to control how transparent your watermark appears. Lower values create a more subtle watermark that is less intrusive while still protecting your image.
