Upload the largest, highest-quality version of your image you have. SiteStakes downsizes — it doesn't upscale. Real estate website branding starts with sharp source files.
For your logo, start with an image at least 800 pixels wide. Anywhere from 1200 to 1600 pixels works best. Save it as a PNG with a transparent background so it sits cleanly on any header color. Logos look best wider than they are tall — aim for a 3:1 or 4:1 aspect ratio.
For your favicon, start with a square image at least 512×512 pixels. 1024×1024 works even better. Save as PNG with a transparent background. Pick a single bold symbol or initial — favicons display at 32×32 pixels in browser tabs, so anything detailed disappears.
If you don't have a favicon yet, your logo's most distinctive element — your icon, monogram, or initial — usually works. Crop tight on that one piece.
