On every freelance marketplace your profile picture is cropped to a small circle, and each platform crops it from a slightly different starting point. A full-resolution photo is both heavier than it needs to be and at risk of an awkward crop, while a carelessly compressed one goes soft exactly where a client's eye lands first — your face. The fix is a square, moderately sized image that is light enough to load instantly and clean enough to hold up when shrunk. Skwish resizes to a square frame and compresses in the browser with a live size readout, so you can find the smallest file that still looks crisp at avatar size. Use the same source photo across Fiverr, Upwork, and a personal portfolio in one batch, and never send a personal headshot to a web service just to shrink it.
