Image Watermark FAQ
Does the watermark tool upload images to a server?
No. ImgLab watermarking runs entirely in your browser. Images and watermarks are never uploaded to any server.
Can I add a text watermark?
Yes. Enter any text, choose font, size, color, and opacity. Position it freely or snap to a 9-grid slot.
Can I add an image watermark?
Yes. Upload a logo or image as the watermark. Adjust its size, opacity, and position on the base image.
Can I adjust the watermark position?
Yes. Use the 9-grid (3x3) layout for precise placement, or drag freely to any position.
Can I watermark multiple images at once?
Yes. Use the batch tool to apply the same watermark to multiple images and download as a zip.
Does it work on mobile?
