Frequently asked questions
What opacity should a watermark have?
Between 30% and 50% keeps the watermark visible without hiding the photo. Tiled watermarks usually work best at 15–30%.
Does the watermark scale with large images?
Font size is relative to the image width, so the watermark looks the same on small and large photos.
Can I watermark a PDF too?
Yes, use our Watermark PDF tool to stamp text on every page of a PDF document.
