How do I use compress png?
Choose PNG from your device, adjust the available settings, review the result and download a new copy. Each source image can be up to 50 MB; large dimensions may exceed your device's memory limits.
Why can a compressed image be larger?
An image may already be efficiently compressed. Re-encoding can increase its size. Compare the original and output byte counts before downloading. JPG and WebP support lossy quality controls; PNG quality sliders do not provide the same compression behavior. AVIF export depends on your browser.
Is this tool free, and do I need an account?
The local image tools are free and do not require an account. Images are processed in your browser. An account is only needed for supported cloud-saved workflow features; model downloads still require internet access.
