How to Add a Watermark to an Image Online (Free)
Watermarking is essential for photographers, designers, and anyone sharing visual work online. It protects your images and asserts ownership — without being intrusive when done right. This guide walks you through adding a text or logo watermark in your browser, with full control over position, opacity, and size.
Text Watermark vs Image Watermark
- Text watermark — type your name, website URL, or copyright notice. Quick to add, universally readable. Best for portfolios and social sharing.
- Image watermark (logo) — upload a transparent PNG of your logo. More professional, harder to remove by retyping. Best for commercial photography and branded content.
Step-by-Step Instructions
Open the Watermark Maker
Go to the Watermark Maker tool. It opens instantly in your browser — no install, no account.
Upload your base image
Click the upload area or drag and drop the image you want to watermark. PNG, JPG, and WebP are supported.
Choose a watermark type
Click the Text tab to type a custom watermark text (name, URL, ©2026), or click the Image tab to upload a transparent PNG logo file.
Set the position
Use the 9-point position grid to place the watermark in a corner, on an edge, or in the centre. Bottom-right or bottom-left are the most common positions for subtle watermarks.
Adjust opacity and size
Use the Opacity slider to make the watermark more transparent (subtle, professional) or opaque (harder to remove). For text, also adjust the font size and colour.
Download
Click Download to save the watermarked image as a PNG. The Canvas API composites the watermark in-browser — your image never leaves your device.
Tips for Effective Watermarks
- Opacity 30–50% — subtle enough to not distract from the image, but visible enough to deter theft.
- Avoid the corners on high-value images — corners are easy to crop. A centred or mid-image watermark is harder to remove.
- Use your website URL as a text watermark — it also works as free advertising when images are shared.
- White with shadow — a white text watermark with a slight dark shadow is visible on both light and dark backgrounds.
