Add Watermark to Photo

Adding a watermark to a photo takes under a minute with the right tool. The process has three steps: upload your image, configure your watermark settings, and download the watermarked result. The tool above handles all three entirely in your browser — no file transfer to a server, no waiting for processing, and no quality loss on the output.

Step 1: Upload Your Photo

Click the upload area or drag and drop your image into the tool. JPEG, PNG, and WebP formats are all supported. The tool reads your image directly into the browser's memory as a local object URL, which means the file data never leaves your computer. There is no file size limit imposed by a server — the practical limit is your browser's available memory, which handles images up to several hundred megabytes for most modern devices. For typical photography files in the 5–30MB range, loading is essentially instant.

Step 2: Configure Your Watermark

Switch between the Text and Logo tabs to configure each watermark layer independently. You can enable one or both simultaneously. For text watermarks, type your name, studio, website, or copyright notice, then choose your font, size, color, opacity, and rotation. For logo watermarks, upload a PNG file (ideally with a transparent background) and adjust the size and opacity to integrate it naturally with your photo. The position grid lets you place the watermark in any of nine positions — corners, edge midpoints, or center. For tiled patterns, enable the “Tile across image” option in the position controls. All changes update the preview canvas in real time so you can see exactly how the final image will look before downloading.

Step 3: Download at Full Resolution

When the watermark looks right, click the Download button. The browser generates the file at the exact same size as your original image — a 6000 × 4000 pixel photograph produces a 6000 × 4000 pixel watermarked output. The download is full quality, with no compression introduced regardless of the original image size or quality. Your watermarked image appears in your downloads folder within seconds.

Watermarking for Different Platforms

The right watermark placement depends on where the image will be used. For Instagram posts, the bottom-right or bottom-left corner is the convention — it is visible in the feed view without interfering with the main subject. Keep opacity moderate (20–35%) since Instagram is a social platform where heavy watermarks can discourage engagement. For portfolio websites, a subtle corner watermark at low opacity signals professionalism without dominating the presentation. For client proof images sent before final delivery, a centered or diagonally tiled watermark at higher opacity (50–70%) is the appropriate choice — the goal is to prevent use of the proof image as the final, not to show off the image. For stock photo previews, the industry standard is a centered diagonal watermark with tiling enabled, which makes the image recognizable as a preview while making the watermark impractical to crop or remove.

Adding Your Signature as a Watermark

A common request is to use a handwritten or stylized signature as a watermark rather than plain typed text. There are two ways to do this with this tool. The first is to use a script font in the Text tab — Brush Script and similar typefaces create a convincing signature-style appearance. The second is to photograph or scan your actual signature, remove the background using our background remover to create a transparent PNG, then upload it as a logo watermark. The second approach gives you an authentic signature watermark that matches the physical signature you use on prints, which can be meaningful for fine art photography and limited edition prints.
