4 Free Developer Tools I Built for Better Social Media Presence

If you've ever shared a link and the preview looked terrible (or was missing entirely), these tools are for you. I built them all as free, no-signup-needed web tools. 1. OG Tag Checker What it does: Paste any URL and instantly see how it looks when shared on Twitter, Facebook, and LinkedIn. Shows all detected meta tags and warns about missing ones. Why it's useful: Social crawlers are picky. Missing an og:title? Your link shows up as a blank card. Wrong image dimensions? It gets cropped awkwardly. This tool catches all that before you share.

Why it's useful: Every new project needs a favicon. Instead of opening Figma or searching for generators with ads, this generates all sizes in one click. Client-side only — your data never leaves your browser. Try it free 3. Social Media Image Resizer What it does: Upload any image
