About Image Watermarking

Watermarking your images helps protect your intellectual property and brand identity. Whether you're a photographer protecting your portfolio, an e-commerce seller branding product photos, or a content creator securing your work — a watermark establishes ownership and deters unauthorized use.

How to Watermark an Image

  1. Upload the image you want to watermark
  2. Choose Text mode for text watermarks or Image mode for logo watermarks
  3. Configure your watermark — font, size, color, opacity, position, rotation
  4. Preview the result in real-time on the canvas
  5. Click "Download Watermarked Image" to save

FAQ

How do I add a watermark to an image?+

Upload your image, choose between text or image watermark mode, configure your watermark (text content, font, color, opacity, position, rotation), and click 'Download Watermarked Image'. The watermarked image is saved as a PNG.

Can I use a logo as a watermark?+

Yes. Switch to 'Image' mode and upload your logo or any image. You can adjust its scale, opacity, rotation, and position on the source image.

What formats are supported?+

You can upload any image format (JPEG, PNG, WebP, GIF, HEIC). The watermarked output is saved as a high-quality PNG.

Is this tool free?+

Yes, completely free. No watermarks on output, no sign-up required, no usage limits.

Are my images uploaded to a server?+

No. All processing happens entirely in your browser using Canvas API. Your files never leave your device.

Can I add a stroke or outline to text watermarks?+

Yes. Enable the 'Stroke' option in text mode to add a colored outline around your watermark text. This improves visibility on both light and dark backgrounds. You can customize the stroke color and width.

How do I tile a watermark across my image?+

Switch the layout mode to 'Tiled' to repeat your watermark across the entire image in a grid pattern. You can adjust the horizontal and vertical spacing, plus the angle for diagonal tiling.

What output formats are supported?+

You can export watermarked images as PNG (lossless, largest), JPEG (lossy, smallest), or WebP (modern, balanced). JPEG and WebP include a quality slider from 1-100%.

Can I watermark multiple images at once?+

Yes. Switch to 'Batch' mode to upload multiple images. The same watermark settings are applied to all images, and the results are downloaded as a ZIP file.

Can I use my own font for text watermarks?+

Yes. Click the upload button next to the font selector to upload any TTF or OTF font file. The font is loaded locally in your browser and added to the font list.

Can I compare the original and watermarked image?+

Yes. Click the comparison icon in the preview toolbar to toggle a before/after slider. Drag the handle to reveal the original on the left and the watermarked version on the right. You can also switch the preview background between dark, light, and transparent checkerboard to check watermark visibility.

Can I zoom into the preview?+

Yes. Use the zoom controls (+/- buttons) or scroll wheel to zoom in up to 500%. Pan by clicking and dragging when zoomed in. Toggle '1:1' to view the image at actual pixel size.

How do I add a watermark to an image?

Upload your image, choose text or image watermark, customize the appearance (font, size, opacity, position), and download the watermarked image.
