About Watermark Image

Watermark Image is a free online tool that stamps repeating text across every part of a photo or graphic. You type your watermark phrase — a copyright notice, studio name, or "DRAFT" label — and the tool tiles it diagonally across the full canvas using the HTML5 Canvas API. Six font families, a pixel-level font size slider, an opacity control from 1% to 100%, a rotation dial from -180 to 180 degrees, and a spacing slider from 50 to 500 pixels give you fine control over how prominent or subtle the mark appears.

The typical use case is protecting images before sharing them online: photographers add a studio name before posting to social media, designers stamp "DRAFT" on mockups sent to clients for review, and content creators mark screenshots before publishing tutorials. Unlike a single-corner logo overlay, this tool tiles the text across the entire image, so cropping away the watermark removes the subject too.

Every operation runs locally in your browser. Your photos are never transmitted to a server, stored, or logged — not even temporarily. The result downloads directly to your device as a PNG or JPEG file at the original image dimensions. There is no account, no usage limit, and no cost.

Key Features

check_circle

Tiled coverage across the full image

Text repeats diagonally in a grid pattern that covers every part of the photo, so no region can be cropped out to remove the mark entirely.

check_circle

Six sliders for precise control

Font size (10-100 px), opacity (1-100%), rotation (-180 to 180 degrees), and tile spacing (50-500 px) are all adjustable with live preview — changes appear instantly without a re-render step.

check_circle

Six font families to match your brand

Choose from Arial, Times New Roman, Courier New, Georgia, Verdana, or Trebuchet MS to match the tone of your brand or the style of the image.

check_circle

PNG and JPEG output at full resolution

Download in PNG for lossless quality or JPEG at 92% quality for smaller file sizes. The output dimensions always match the original image exactly.

check_circle

Accepts JPEG, PNG, WebP, BMP, and GIF

Any common image format you drop in is supported. The tool reads the file locally via an object URL, so there is no conversion step before you start editing.

Client-side only — zero uploads

The Canvas API draws and exports entirely in your browser tab. Confidential product shots, client mockups, and personal photos never leave your device.

Example

A photographer uploads a 3000x2000 JPEG portfolio shot. They type their studio name, set opacity to 25%, rotation to -30 degrees, font size to 36 px, and spacing to 180 px. The text tiles diagonally across the entire image at low opacity, visible enough to deter copying but not distracting when the image is viewed at normal size. They download as PNG and the filename becomes photo_watermarked.png.

Common Use Cases

  • arrow_circle_right

    Protecting portfolio photos before online sharing

    Photographers post work-in-progress shots and full portfolios to Instagram, Behance, or personal sites. A tiled studio-name watermark discourages right-click saving without obscuring the composition, unlike a single corner stamp that can be trivially cropped.

  • arrow_circle_right

    Marking design mockups sent to clients for approval

    Design agencies send mockups for client review before payment is received. Stamping "DRAFT — NOT FOR USE" at low opacity across the frame makes the approval status clear while keeping the design legible, which a resizer or compressor does not do.

  • arrow_circle_right

    Labelling confidential screenshots and documentation images

    Product teams circulate pre-release screenshots for internal review. Adding a "CONFIDENTIAL" watermark at a visible opacity signals the sensitivity of the material and creates a deterrent against external sharing.

  • arrow_circle_right

    Branding tutorial and educational content

    Online educators and YouTube thumbnail creators embed a channel name or website URL across instructional screenshots before publishing. Tiled text ensures the brand attribution survives any crop or resize the viewer might apply.

  • arrow_circle_right

    Preparing stock photo previews

    Independent stock photographers distribute watermarked previews to potential buyers. Full-canvas tiling prevents buyers from using the preview in place of purchasing the licensed file, a use case where resizing or compression tools are irrelevant.

Frequently Asked Questions

What is Watermark Image? expand_more
Watermark Image is a free online tool that adds repeating text watermarks to your images. You can customize the text, font size, color, transparency, rotation angle, and spacing to create professional watermarks that protect your photos.
Is my image uploaded to a server? expand_more
No. All watermark processing happens entirely in your browser using client-side JavaScript and the Canvas API. Your images never leave your device, ensuring complete privacy and security.
Can I adjust the watermark transparency? expand_more
Yes. The opacity slider lets you control how transparent or opaque the watermark appears, from 1% (nearly invisible) to 100% (fully solid). A setting around 20-35% is typical for portfolio photos — visible enough to deter copying without obscuring the subject.
What output formats are supported? expand_more
You can download your watermarked image as PNG (lossless) or JPEG (92% quality, smaller file size). The output always matches the original image dimensions exactly.
How is this different from the Image Resizer or Image Compressor tools? expand_more
Image Resizer changes the pixel dimensions of a photo and Image Compressor reduces its file size — neither alters the visual content of the image. Watermark Image adds visible text overlaid on the image to signal ownership or status. The tools serve different purposes and you can use them in sequence: watermark first, then compress for web delivery.
Can I control how the text is tiled across the image? expand_more
Yes. The spacing slider (50-500 px) controls how far apart each repetition of the text is placed. Tight spacing (50-100 px) creates a dense pattern that covers even small gaps; wide spacing (300-500 px) gives a sparse, less intrusive look.
Does the rotation slider affect just the text or the whole image? expand_more
Only the watermark text is rotated. The underlying image stays upright. The default rotation is -30 degrees, which produces the classic diagonal watermark look, but you can set any angle from -180 to 180 degrees.
Which font families are available? expand_more
Arial, Times New Roman, Courier New, Georgia, Verdana, and Trebuchet MS are available. These are system fonts that render consistently across all browsers without requiring a font download.
Is there a file size or image resolution limit? expand_more
There is no enforced limit. Because all processing runs in your browser tab, performance depends on your device. Very large images (above 20 megapixels) may take a moment to render but will complete without error on modern hardware.
