Why is my PNG not much smaller?

Lossless PNG encoding rarely shrinks a file much. Choose 256 or 64 colours to reduce the palette. The file gets much smaller, but fine colour detail can be lost.

Are my photos uploaded?

No. Compression runs in your browser. Re-encoding also removes metadata, including the location where a photo was taken.
