Why are PNG files so large in the first place?

PNG uses lossless compression, which keeps every pixel exact. That makes it great for logos and text, but it produces huge files when used for camera photos.

Are my PNG images uploaded to a server?

No. The conversion happens inside your browser using your device's own processor, so nothing leaves your computer or phone.

Can I compress multiple PNG files at once?

Yes. There is no daily limit, and you can batch compress many files at the same time.
