Why use the compress png to 400kb?

One job, done well: your PNG at 400KB, with the true size shown and your privacy kept. No uploads, no accounts.

Targets 400KB exactly

The engine keeps adjusting quality and size until your PNG is at or under 400KB — then shows you the real final size.

Private by design

Files never leave your browser. No uploads means no waiting for servers and nothing for anyone to snoop on.

Honest numbers

Every run reports the true output size. If a target is out of reach, you get a clear note — not a made-up figure.

Free, no account

PNG-smart compression

PNG files are rebuilt with a smaller color palette, so transparency survives — no forced conversion to JPG.

Phone, tablet, desktop
