Client-Side OnlyWhat Is an Image Watermark?
A watermark is text or a logo overlaid onto an image, usually semi-transparent, to mark ownership, brand a photo, or discourage unauthorized use. Photographers, businesses, and content creators add watermarks before sharing images publicly so their work stays identifiable even if it's copied or reshared elsewhere.
NexaTools Image Watermark Tool draws your chosen text or logo directly onto an HTML5 canvas at the position, size, color and opacity you set, entirely inside your browser.

Privacy: Why Browser-Based Watermarking Matters
Many online watermark tools require uploading your image and logo to a remote server before returning a result, which means your files briefly or sometimes permanently live on someone else's infrastructure. NexaTools Watermark Tool avoids that entirely. The watermark is applied locally using your browser's Canvas API, so nothing leaves your device, there's no server round-trip, and nothing about your image is logged or stored anywhere.
Tips for Getting the Best Results
1. Use moderate opacity
A watermark around 50 70% opacity is visible enough to identify your work without overwhelming the image underneath.
2. Corner placements are less intrusive
Bottom-right or bottom-left positions keep the watermark visible while staying out of the main subject of most photos.
3. Use a transparent PNG for logo watermarks
A logo with a transparent background blends into the image naturally, while a solid background will show as a visible box.
4. Match text color to your image
Light text works best on darker images and dark text on lighter images use the color picker to keep it readable.
Common Problems & Troubleshooting
Running into an issue while adding a watermark? Here are fixes for the most common problems:
⚠️ Watermark is hard to see
Increase the opacity slider, or switch to a text color that contrasts more with your image.
⚠️ Logo shows a solid box around it
Your logo file likely doesn't have a transparent background. Use a PNG logo with transparency for a cleaner result.
⚠️ Watermark looks too large or too small
Adjust the Size slider it scales the text or logo relative to the image dimensions.
⚠️ "Could not process this image"
The file may be corrupted or in an unsupported format. Confirm it's a valid JPG, PNG, or WebP file and try again.
⚠️ File larger than 20 MB
Very large images aren't supported in-browser. Try compressing the image first, then add the watermark.
⚠️ Download button doesn't work
