What this tool is for
Sharing images on the web without any attribution is an invitation for them to be reused without credit. A watermark — whether a copyright line of text or a small logo in the corner — ties the image back to its creator even after it has been downloaded, screenshotted, or reposted. The Image Watermark Tool applies text or image watermarks to photos directly in your browser, with controls for position, opacity, scale and rotation, and outputs the result as a clean download with no extra branding added.
Photographers use it to protect portfolio shots before client approval, adding a semi-transparent name in the bottom-right corner so the image is viewable but not print-ready. Small businesses stamp a logo on product photos before publishing them to a store or social feed. A batch of 20 runs in one pass with identical settings and comes back as a single ZIP.
For text, configure font family, size, color, bold, italic, and an optional outline or drop shadow so pale type stays legible over a bright sky — then place it with a nine-point anchor grid and X/Y offsets, or drag it anywhere on the side-by-side live preview. Tile mode repeats the mark across the entire frame at whatever angle you set, which is far harder to crop away than one corner stamp. A "scale to each image" switch treats size and offsets as percentages, so a 4000-pixel shot and an 800-pixel one come back looking identical. All watermarking happens on a canvas in your browser; your photos are never uploaded.
How to use the Image Watermark Tool
- Drop your photos onto the upload zone, then click any file in the list to preview that one.
- Click Text to type a watermark (copyright line, name, URL) or Image to upload a logo file.
- For text: set font, size and color, and turn on Outline or Drop shadow if the mark vanishes against a light background. For image: adjust the scale percentage.
- Pick a spot on the nine-point grid and fine-tune with X/Y offsets, or drag the watermark directly on the preview.
- Tick "Tile across the whole image" and set a rotation angle for a repeating diagonal pattern.
- Choose an output format and quality, click Apply, then download the results individually or as one ZIP.
What the Image Watermark Tool gets right
- Nine-point anchor grid, pixel or percentage offsets, and drag-to-place on the preview cover both exact coordinates and quick eyeballing.
- Tile mode repeats the watermark across the full frame at any angle, so it cannot simply be cropped off a corner.
- "Scale to each image" keeps a mixed-resolution batch consistent: the mark occupies the same fraction of every photo instead of a flat 48 pixels on all of them.
- Output format and quality are yours to choose — keep PNG transparency, or flatten to JPG at a size you control.
- Browser-only processing with no upload: original high-resolution photos stay on your device even while being watermarked.
Frequently Asked Questions
What opacity setting makes a watermark visible but not distracting?
A value between 30% and 50% is the most common range for protecting images while keeping the subject clearly visible. At 50% the watermark is obvious but not harsh. Below 20% it may be too easy to clone-stamp out in an image editor. For preview watermarks you want to be clearly unremovable, 70–80% opacity is more appropriate.
Can I watermark a transparent PNG with a logo?
Yes. Choose Image mode, upload your logo, and set Output Format to PNG — or leave it on "Same as source", which already keeps a PNG as a PNG, transparency untouched. Selecting JPG instead flattens transparent areas onto white, since JPG carries no alpha channel; the tool warns you before that happens.
What font families are available for text watermarks?
The tool provides seven system fonts: Arial, Helvetica, Times New Roman, Georgia, Verdana, Courier New and Impact. These are standard fonts guaranteed to render consistently across browsers without needing a font download.
Is my image uploaded to a server when I watermark it?
No. All watermarking is done on an HTML5 canvas in your browser. Your photos are read from local memory and the watermarked result is saved back to your device as a local download. No data is transmitted to any server.
