Images & Media
Images are usually the heaviest part of a web page and the biggest opportunity to make it faster. But getting them right means understanding a few things: which format to use, how much you can compress before quality suffers, and what information a photo quietly carries with it.
This cluster walks through preparing images for the web the right way — smaller, sharper, and without leaking data you didn't mean to share. Every tool linked here runs in your browser, so your photos never leave your device.
