Does this tool preserve the image quality?

It tries to keep the picture as clear as possible while meeting the 20 KB target. Very detailed photos may need to be simplified more to fit the limit, but the tool always shows the final file size before you download.

Is my file uploaded to a server?

No. The whole conversion happens in your browser, so the file never leaves your device.
