What is an image watermark?

An image watermark is a visible overlay — usually text or a logo — placed on top of an image to indicate ownership, copyright, or to prevent unauthorized use. Watermarks can be semi-transparent and positioned in various ways to protect images while still allowing viewers to see the content.

What formats are supported for input and output?

This tool accepts PNG, JPG/JPEG, and WebP images as input. The watermarked image is downloaded in the same format as the original. If you upload a PNG, you get a watermarked PNG. If you upload a JPG, you get a watermarked JPG. This preserves the original format's characteristics.

What positioning modes are available?

There are four positioning modes: Center places a single watermark in the middle of the image. Tiled repeats the watermark text across the entire image in a grid pattern, providing maximum coverage and protection. Corners places the watermark in all four corners of the image. Each mode is suitable for different use cases and protection levels.

Can I customize the watermark appearance?

Yes, you can control: font size (from 12px to 200px), text color (via color picker), opacity (from 10% to 100% transparency), and rotation angle (from -180° to 180°). All changes are previewed in real time on the canvas, so you can see exactly how the watermark will look before downloading.

Is the tiled watermark truly covering the whole image?

Yes, the tiled mode repeats the watermark text in a grid pattern with configurable spacing. The spacing automatically adjusts based on font size to provide comprehensive coverage. Combined with diagonal rotation and low opacity, it creates a professional-looking protective overlay.

Does the watermark affect image quality?

For PNG output, there is zero quality loss — the watermark is drawn on a lossless canvas. For JPG output, the canvas is exported at maximum quality (100%), so any quality impact is minimal. The watermark itself does not degrade the underlying image data.

Can I remove a watermark added with this tool?

No, watermarks added to the image become part of the pixel data and cannot be easily removed. This is by design — the purpose of a watermark is to be permanent and difficult to remove. Always keep your original, unwatermarked images as backups.

Are my images uploaded to a server?

No. All watermark processing happens entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server. The watermark is drawn on a local canvas and the result is downloaded directly from your browser.

What is the best opacity for a watermark?

For most purposes, 20-40% opacity provides a good balance between visibility and not obscuring the image. For maximum protection with tiled mode, 10-20% opacity with rotation works well. For copyright notices in corners, 30-50% opacity makes the text clearly readable.

Is this watermark tool free?

Yes, this tool is 100% free with no usage limits, no subscriptions, no sign-ups, and no hidden fees. Add watermarks to as many images as you need. There are no watermarks added by the tool itself — only the text you specify.

White watermarks work well on dark images; use black or dark colors on light images.
Adjust font size relative to your image dimensions — large images need larger watermark text.
Always keep your original, unwatermarked images as backups in case you need them later.
For web use, compress watermarked images with our Image Compressor before uploading.
