How to Add a Watermark
Upload your image by clicking Browse or drag-and-dropping it into the upload area. Type your watermark text in the text field — for example your brand name, website URL or copyright notice. Choose your font, color and size, then select a position on the image. Click Download Watermarked Image to save the result as a PNG.
Choosing Watermark Position
The best position depends on your image content. Center is the hardest for anyone to crop out, making it effective for protection. Bottom-right is the most common convention for subtle copyright notices. Tiled mode repeats the watermark across the entire image, offering the strongest protection since no crop can remove all copies.
Watermark Opacity Tips
A very high opacity (above 80%) makes the watermark readable but may distract from the image. A lower opacity (30–60%) blends the watermark naturally with the background. For portfolio images you want credited but not obscured, 40–50% opacity at bottom-right is a widely used approach. For maximum protection where image content is secondary, 70–80% at center or tiled works best.
Batch Watermarking
This tool processes one image at a time in the browser. For batch watermarking of many images, consider running a command-line script using ImageMagick or a server-side process. This browser tool is ideal for quick one-off watermarks without installing software or uploading files to a third-party service.
Frequently Asked Questions
What image formats are supported?
JPEG, PNG, WebP and GIF (first frame) files are supported. The output is always saved as a PNG to preserve quality and potential transparency.
Can I add an image watermark instead of text?
This tool focuses on text watermarks. For logo-based watermarks, use an image editor such as GIMP or Photoshop, or look for a dedicated image watermark tool that accepts two inputs.
Does the watermark affect image quality?
No — the image is drawn to a canvas at full resolution. The output PNG has no lossy compression, so image quality is preserved exactly as loaded.
How do I remove a watermark from an image?
This tool adds watermarks but does not remove them. Always keep the original file as a backup. Watermark removal is generally not fully reversible without the original image.
