Frequently asked questions (FAQ)
What is a watermark?
A watermark is a text or logo overlay on a digital image. Its primary purpose is copyright protection, branding, and preventing unauthorized use of your photos on the internet.
Are my images sent to a server?
No. The ScanWeb Image Watermark tool uses HTML5 Canvas technology, meaning the image is processed solely in the memory of your device (phone or computer). Your image never leaves your browser.
Does the tool reduce the quality of my original image?
No. The image is exported in the exact dimensions you uploaded it. The only modification is the addition of the text you defined. We recommend using PNG format for maximum quality.
