Watermark Generator

The Watermark Generator is a free browser-based tool that lets you add custom text or image watermarks to any photo. You can control the opacity, position, font, color, size, and rotation of the watermark, then download the result in PNG, JPEG, or WebP format — all without uploading your images to any server.

Upload your image by clicking the upload area or dragging and dropping a file. Make sure "Text" is selected as the watermark type. Enter your desired watermark text, choose font, size, color, opacity, and position, then the preview updates automatically. Click "Download" to save the result.

Yes. Switch the watermark type to "Image" and upload your logo or icon. PNG files with transparency work best as the background will remain transparent, blending naturally with the base image. Adjust the size percentage and opacity sliders for the best result.

Absolutely. All image processing happens entirely in your browser using the HTML5 Canvas API. No images are uploaded to any server, and nothing is stored anywhere. Your files stay on your device throughout the entire process.

You can upload JPG, PNG, WebP, and GIF images as the base photo. For the watermark image, any browser-compatible format is accepted. You can export the final watermarked image as PNG, JPEG, or WebP.

The "Tiled" position repeats the watermark across the entire image in a grid pattern, providing maximum coverage and protection. This is commonly used on stock photo preview images or when you want to make it difficult to remove the watermark by cropping.

Use the Opacity slider to control how transparent your watermark appears. Values around 30–50% create a subtle, semi-transparent effect that does not distract from the photo. For a more prominent watermark, use values above 70%.

Yes. The Rotation field accepts values from -180° to 180°. A common choice is -30° or -45° for a diagonal watermark, which is harder to remove cleanly. You can enter any angle to suit your design needs.

PNG is recommended when your watermark uses transparency or when you need lossless quality. JPEG produces smaller file sizes and is ideal for photographs. WebP offers the best compression with modern quality, but may not be supported in older software.

The font size is scaled relative to an 800px reference width. On very large images, the text will appear proportionally larger so it remains visible regardless of the base image resolution. You can fine-tune the size with the Font Size input to get the exact appearance you want.

Yes. There are no usage restrictions. You can use this tool to protect photographs, brand marketing materials, create watermarked previews of products, or add copyright notices to any digital images for commercial purposes.
