What is this used for?

Verify file integrity, detect duplicate images, or confirm two files are identical byte-for-byte.

Is my image uploaded?

No. Hashing happens entirely in your browser.

Will resizing change the hash?

Yes. Any byte change produces a different hash. Identical files only match if every byte is the same.
