// FAQ
What types of watermarks can I add?
You can add text watermarks with custom fonts, sizes, colors, and opacity, or overlay an image watermark (like a logo) with adjustable size and opacity.
Does it upload my images?
No. Everything runs 100% client-side in your browser using the Canvas API. Your images never leave your device.
Can I tile the watermark across the entire image?
Yes. Enable the tiling option to repeat the watermark diagonally across the entire image, perfect for protecting portfolio images or stock photos.
What export formats are supported?
You can export as PNG (lossless) or JPEG with an adjustable quality slider from 10% to 100%.
Can I use my own logo as a watermark?
Yes. Switch to the Image tab in the watermark type selector and upload any PNG, JPG or WebP image. Transparent PNGs work best for logos.
What position options are available?
Nine positions: top-left, top-center, top-right, middle-left, middle-center, middle-right, bottom-left, bottom-center, and bottom-right. You can also enable tiling to cover the full image.
