How to Add Text, Image, Tiled, and Diagonal Watermarks to Images

Image watermarks can be text or logos. Position, opacity, rotation, and tiling decide whether the mark is useful without distracting from the image.

Adding a watermark is not just placing a logo on top. The mark should be visible without damaging the main image.

Text Watermark or Image Watermark?

TypeBest forTip
Text watermarkAuthor names, URLs, order IDs, internal labelsTune size and opacity carefully
Image watermarkBrand logos, campaign marks, copyright stampsUse transparent PNG when possible
Tiled watermarkDiscouraging reposts and screenshotsKeep opacity low
Diagonal watermarkContracts, samples, review imagesKeep rotation and spacing consistent

When to Use Nine-Grid Positioning

Nine-grid positioning is useful for a single watermark. Bottom-right works well for copyright marks, center works for samples, and corner marks usually cover less important content.

Which Output Format Should You Use?

  • Use JPG or WebP for photos when smaller files matter.
  • Use PNG for screenshots, transparent images, and UI assets.
  • Keep the transparent logo source if your watermark is an image.
  • Preview on mobile and desktop before publishing.
