Drop an image below and this tool resizes it to 600×600 pixels, entirely inside your browser — no upload, no install, no sign-up. A common digital starting size for passport-style photos is a square image around 600×600px (roughly 2×2 inches at 300 DPI).
With aspect ratio lock on (the default), the tool computes the matching dimension from your image's own proportions so the result isn't stretched or distorted — it never crops your photo. Turn the lock off if you need to hit this exact box regardless of your image's original shape. This is a common digital starting size, not an official government specification — official passport and visa photo requirements (exact dimensions, head size, background) vary by country and agency, so always verify the exact requirement before submitting a photo.
