Question 1

What types of watermarks can I add?

Accepted Answer

You can add text watermarks with custom fonts, colors, and outlines, or upload a logo/image watermark (PNG recommended for transparency). Both types support opacity control, rotation, 9-point positioning, and full-image tiling.

Question 2

Can I watermark multiple images at once?

Accepted Answer

Yes. Upload multiple images and the same watermark settings will be applied to all of them. Sizes are percentage-based so the watermark scales proportionally to each image. Download individually or as a ZIP archive.

Question 3

Are my images kept private?

Accepted Answer

Yes. All watermarking happens 100% in your browser using the Canvas API. Your images are never uploaded to any server. They stay on your device the entire time.
