02 / Best for

Shrink screenshots and UI assets before sharing them.

03 / Why here

Real savings, honestly achieved: the PNG is re-encoded as WebP, which keeps transparency and typically cuts 60-90% of the size.
No file count or size caps: your hardware does the work, so we have no limits to impose.
Runs entirely in your browser, so images never leave your device.

04 / Keep in mind

The output is WebP, not PNG: re-encoding PNG as PNG rarely saves real space. Use WebP to PNG afterwards if you specifically need PNG back.
The Extreme and Recommended profiles also downscale very large images.

faq

Questions, answered.

01Why is the output WebP instead of PNG?

Because that is where the real savings are. WebP keeps transparency and typically cuts 60-90% of the size, while re-compressing a PNG as PNG saves almost nothing. Every modern browser and editor opens WebP; if you need PNG back, the WebP to PNG converter is one click away.

02Is transparency preserved?

Yes. WebP has full alpha support, so transparent logos and UI elements stay transparent.

03Is Compress PNG free to use?

Yes, Compress PNG is completely free, with no sign-up and no usage limits. It runs entirely in your browser, so your data never leaves your device.
