Resize Image to 400×400

400×400 is profile-photo canon — X/Twitter\'s spec and the safe square across professional platforms. Big enough for a confident face, small enough to load instantly. Resizing keeps the aspect handling honest — no stretching or squashing; the output is exactly the dimensions you asked for.

The face-first square

Profile photos exist to make you recognizable at a glance — 400px holds clear facial detail while platforms render it down to chat-bubble size. Tight framing (head and shoulders) is what survives that whole range.

One headshot, everywhere

A well-framed 400×400 headshot serves social profiles, professional networks, team pages and app accounts identically — the personal-brand master square.
