Frequently Asked Questions
Are my images uploaded to your servers when I add a watermark?
Absolutely not. Image Studio processes everything locally on your device using HTML5 technologies. Your photos never leave your web browser, ensuring maximum security, privacy, and speed.
Can I use my own custom fonts for the watermark?
Yes! Along with a library of predefined fonts like Arial, Impact, Courier New, and Roboto, you can easily import any custom font by pasting its web URL directly into our tool.
Can I make the watermark background or text semi-transparent?
Yes, you have complete control over opacity. You can adjust the transparency of the text, apply a custom semi-transparent background block, or configure a subtle drop shadow to make the text pop on complex backgrounds.
Does this tool support precise positioning and rotation?
Definitely. You can manually drag and resize the watermark container directly on the canvas, rotate it to any precise degree, or key in exact X/Y pixel coordinates for perfect alignment.
