Questions
What's the difference between the two methods?
Smaller reduces the image to at most 256 colours and stores it as a palette image, which often cuts the size by 60 to 80 percent. No change at all keeps every pixel exactly and only stores the file more efficiently, usually saving 5 to 30 percent.
Will my PNG look different?
Logos, icons, screenshots, and drawings look the same with Smaller. Photos and smooth gradients may show slight banding; choose No change at all for those.
Is transparency kept?
Yes, with both methods, including soft see-through edges.
Are my images uploaded?
No. Your files are processed on your device. We never upload them.
Can I compress a PNG to a specific size?
Yes. Choose Reach a file size. With Smaller, the tool tries fewer colours until it fits; if that isn't enough, it makes the image smaller in pixels and says so.
Should I convert to WebP instead?
For websites, WebP is often smaller than any PNG and keeps transparency. Use PNG to WebP for that; keep PNG when a program or site asks for PNG.
