Design asset tools handle the boilerplate "I need an X for my project" tasks: favicons in the right sizes for browser tabs and home-screen shortcuts, social media dimensions for OG image templates, and the supporting assets that every web project needs but nobody enjoys producing.
The favicon generator takes a single source image and produces the complete set of favicon files modern browsers expect: 16×16 and 32×32 PNGs for browser tabs, 180×180 for iOS home-screen shortcuts, 192×192 and 512×512 for Android and PWAs, and the legacy .ico file with multiple bundled sizes for older Windows browsers. Output is a downloadable zip ready to drop into your site root.
For social media image dimensions, the reference covers the current specs for each major platform (Twitter, Facebook, LinkedIn, Instagram, YouTube, Pinterest), including both the in-feed image dimensions and the link-preview / OG image dimensions. Specs change every few months as platforms tweak their layouts; the reference here is dated so you know how recent the values are. Any asset you produce ought to be tested in the actual platform before launch, since preview tools like Twitter's Card Validator catch issues the spec doesn't document.
