Common questions

How much smaller will my PNG get?+

Screenshots, logos and flat graphics often shrink 40-80% with palette optimization. If a PNG is already optimized, we tell you and hand back the original untouched — never a bigger file.

Does it keep transparency?+

Yes — PNG transparency is preserved. Unlike some tools that route PNG through JPG (losing the alpha channel), we keep it a real PNG.

Does it stay a PNG?+

Yes. We just re-encode it smaller. To switch to a smaller format like WebP, use our converters instead.

Is my image private?+

Yes. Uploaded over an encrypted connection, compressed on our own server with no third-party APIs, and deleted within one hour.

Is there a limit?+

No watermark, no signup, and generous file sizes — free to use.
