Watermark Maker takes two images: the base image you want to protect or brand, and a separate watermark image. In practice, that watermark is usually a transparent PNG logo, badge, signature, or small brand mark. Once both files are loaded, the preview updates as you change position, opacity, size, padding, and blend mode.
The tool is best for quick one-off images: a product shot, a portfolio preview, a social post, or a draft you want to send without sharing a clean original. It exports a PNG result from the browser canvas.
Very small logos can look soft if you scale them up too far, so it is better to start with a watermark image that is larger than you think you need. If the watermark disappears on a bright or dark photo, change the blend mode or raise the opacity a little instead of making it huge.
Processing happens with browser image APIs and canvas. There is no account step and no server-side render queue; you choose the files, adjust the preview, and download the result from the page.
No. This version uses an image watermark. If you need text, create the text as a transparent PNG first, then upload it as the watermark.
PNG is the safest choice for logos because it can keep transparency. That helps the mark sit on top of the photo without a white box around it.
The generated image downloads as PNG, using the base file name with a watermarked suffix.
