Add Watermark to Photo

Common Use Cases for Photo Watermarks

Watermarking serves different purposes depending on your workflow. Here are the most common scenarios.

Protecting photography portfolios. Photographers share preview galleries with clients before final delivery. A semi-transparent watermark across each proof image lets clients evaluate composition and color while preventing unauthorized use of the full-resolution file. Use the tiling option to cover the entire frame so the watermark cannot be cropped out.

Branding product and social media images. E-commerce sellers, bloggers, and content creators add a logo or handle to every image before publishing. Consistent watermark placement — such as the bottom-right corner at 30-40% opacity — reinforces brand recognition without distracting from the content itself.

Marking drafts and confidential documents. Before circulating design mockups, architectural renders, or internal reports, overlay a tiled "DRAFT" or "CONFIDENTIAL" text watermark. This signals that the document is not final and discourages premature distribution.

Real estate and rental listings. Property managers watermark listing photos with their agency logo to maintain attribution as images get re-shared across multiple listing platforms.

Art and illustration previews. Digital artists share low-resolution previews on social platforms with a diagonal watermark to deter art theft while still showcasing their style and skill.

Guide to Effective Watermarking

A well-placed watermark balances visibility with aesthetics. Too faint and it offers no protection; too prominent and it ruins the image. Start with 40-60% opacity for text watermarks and adjust from there. White text with a subtle drop shadow works on most photos, but switch to a dark color for light-toned images.

Positioning matters. A single watermark in one corner can be cropped out easily, so consider tiling the watermark diagonally across the image if theft prevention is your primary goal. For branding, a small logo in the bottom-right corner is the industry standard — it is visible enough to identify the creator without competing with the subject.

This tool processes everything using the HTML5 Canvas API directly in your browser. Your original image is drawn onto an invisible canvas, the watermark is composited on top at the opacity and rotation you specify, and the final result is exported at the full native resolution of your original file. No pixels are lost, no server ever sees your photo, and the output is free of any branding from this tool.

Logo watermarks should be PNG files with a transparent background for the cleanest result. The tool preserves the alpha channel of your logo, so the watermark blends naturally with the underlying photo. Adjust the logo size slider to scale relative to the image width — 15-25% is a good starting range for corner placement, while 8-12% works better for tiled patterns.

You can export in PNG for lossless quality, JPG for smaller file sizes ideal for web use, or WebP for the best balance of quality and compression supported by all modern browsers.
