Add a text watermark to your photos online for free with ResizerPhoto. Protect your images before sharing them online, prevent unauthorized use, or brand your photos with your name or website. Our watermark tool works entirely in your browser — fast, private and free.
Adding a text watermark to a photo is a quick way to mark ownership before sharing images publicly, whether that's a photographer protecting their portfolio samples, a business adding its name to product photos before posting them online, or simply labeling a personal photo with a date or event name. Desktop watermarking tools often require setting up templates or working through multiple menus just to place a single line of text, when the core task is usually as simple as choosing the text, its position, and how visible it should be.
For a watermark that protects your work without overwhelming the photo, a moderate opacity setting combined with placement in a corner rather than dead center tends to strike the right balance between visibility and not distracting from the main subject. Because the watermark becomes part of the actual image data once downloaded, it travels with the file wherever it's shared or re-uploaded, unlike metadata-based ownership information which many platforms automatically strip out during upload.
The watermark is drawn directly onto the image using the canvas API's text rendering functions, where the tool sets a font size proportional to your image's width so the watermark scales sensibly whether you're working with a small thumbnail or a large full-resolution photo. The text color and opacity are configurable, with the opacity value controlling how much the watermark blends into the photo beneath it — a lower opacity produces a subtle, semi-transparent mark that doesn't distract from the image content, while a higher opacity creates a bold, clearly visible label. Positioning is handled using percentage-based coordinates rather than fixed pixel values, so the watermark's placement scales correctly and consistently regardless of the original photo's exact dimensions. Because the watermark text is rendered as part of the image itself rather than as a separate overlay layer, the downloaded file has the watermark permanently baked into the pixel data, exactly as it appeared in the preview.
Because font size, opacity, position, and color are all independently adjustable, the same tool can produce anything from a barely visible copyright mark meant only to establish ownership without affecting how the image looks, to a bold, clearly branded overlay meant to be immediately noticed, such as a business name displayed prominently across a promotional graphic. It's generally advisable to place a watermark somewhere that would be genuinely difficult to crop out without losing meaningful parts of the photo, such as across the lower third of the image rather than tucked into a far corner that could simply be trimmed away, if protecting the image from unauthorized reuse is the primary goal rather than just labeling it for personal reference.
Currently our tool supports text watermarks. For image-based watermarks, use the Add Border or Overlay tools.
Use the opacity slider to adjust transparency. Lower values make the watermark more transparent.
The watermark is placed across the image. Adjust size and opacity for best visibility.
Yes. The watermark is baked into the downloaded image and cannot be removed from that copy.
Any text — your name, website URL, copyright notice or any custom label.
Yes. Use one tool, download the result, then upload that file into another tool on this site to layer edits.
No, this changes how the pixels look, not how many pixels the image has.
Yes, any standard JPG, PNG, or WebP photo from a phone or camera works with this tool.
