Compress
Compression re-encodes a file at a smaller size, trading detail you won't notice for bytes you will. Pick the tool that matches what you have: a JPG or PNG, a mixed batch of images, or a video re-encoded to H.264. You see the saving before you download anything, and the originals never leave your machine because every byte is crunched in your browser.
