Tips for social media image quality

• Most platforms recompress images on upload. Uploading at the exact recommended dimensions minimizes this recompression effect.
• For profile photos that display as circles, center your subject and leave room around the edges.
• Text in social images should stay within the central 80% of the image to avoid cropping on mobile.
• Test your image by previewing it on mobile before publishing — mobile displays often crop differently than desktop.
