Step-by-Step Guide
4 steps · takes under 1 minute
Instagram: bottom-left, inside safe zone
Instagram crops the bottom of feed images with UI elements. Place your watermark in the bottom-left, 5% in from the edge, to stay in the safe zone.
Pinterest: bottom-center
Pinterest images are viewed full-width in a masonry grid. Bottom-center is highly visible and hard to crop without losing the image.
Twitter/X: avoid top-right corner
Twitter shows image previews cropped from the top. Place watermarks in the center or lower portion of the image.
Facebook: bottom-right, subtle opacity
Facebook's audience skews toward sharing rather than professional use. A subtle 30–40% opacity watermark is appropriate.

Pro tip
Pre-optimizing images before uploading to a platform gives you more control than relying on the platform's automatic (and often aggressive) compression.
